UX32VD. Which fan-control

Hi,
I found to fan-controls for the UX32VD. Does anyone tested one of that. Which is better?

Murmel

I recently purchased the Yoga 2 13 and had the same problem with fan noise. I decided to open up the laptop and remove the cpu fan and heatsink. The heatsink and cpu had way too much thermal compound smeared on them--much too thick. I cleaned both and applied a tiny drop of compound to the cpu and reseated the heat sink. I also placed some thin strips of foam under the fan and screwed it back on. The foam prevents the fan from having direct contact with the metal underneath. I closed up the laptop, plugged it in, and booted up. The laptop is now almost silent although the fan is still running and temperatures are normal. Couldn't believe it. I think the foam really helps reduce the vibration resulting fromt eh contact between the fan and the metal underneath it. Try it.

User-developed Fan Control for the S10(e)

Hello and welcome.
When you've searched the internet and found this thread, it's possible that you are an owner of a Lenovo Ideapad S10 or S10e which has a little problem with the behaviour and/or the noise of the fan. In this post you will get all the informations you need to handle this problem for yourself. It should also be the same on every S9/S9e.
Just a few comments before we begin:
This is not an official support or solution by Lenovo.
We are just normal users as you are, but we get rid of the fan and wanted to find a way to handle it. So if you want to try anything of the methods described here you have to know that you'll do all this only at your own risk. We are not responsible for any damages of your device. You should only use these methods if you know what you are doing.
Please note that this thread is only for discussing, improving, trouble shooting and perhaps extending the fan control utilities. Any general complaints about the fan problem itself should be placed in the original thread right here: http://forums.lenovo.com/lnv/board/message?board.id=IdeaPad_Netbook&thread.id=795. It already has 80+ pages (the link goes to the first page) and it is better to exclude all the fan control stuff because there it's very difficult to keep an overview.
Here you may post all of your questions, ideas/brainstorming, concerns, thanks and so on and you are really invited to participate and be an active member.
In this first part of this post I'm going to summarize all information about using a fan control utility. For any newbie it will be enough to read this post to get all necessary information. The second part does the same for developement of fan control utilities as we still have no known or working fan control utility for Linux, Mac OS X and other OSs I've forgotten - for now.
For getting started you need a S10 or S10e with an up-to-date BIOS. For the S10 it's the 90 67, for the S10e the 66.
The battery issue
Under very specific circumstances - that we haven't figured out yet - it might happen that your Lenovo S9/10(e) no longer detects the battery while using S10FanControl or S10Fan. It might occur after 2 minutes, it might occur after 2 months, it might never occur. It does not occur using Notebook Hardware Control.
It can be solved by removing the battery, waiting 10 seconds and put it back in. Then the battery is re-initialized and the detection works again.
S10FanControl - Windows
The first utility is S10FanControl created by user dresslerc. The current version is 1.0.0.1, available here: http://www.mediafire.com/file/yd5xmnrnijf/S10FanCtrl1.0.0.1.zip. After you've downloaded it you just have to extract it and start the .EXE in the "Release" folder. Here are the notes and the description dresslerc posted right here:
Everyone,
I've uploaded a version which everyone can use to test with. Remember this is still a TEST version although I think it works for the most part. It should work both on the S10/S10e.
Please install the .NET Framework 2.0 or later first.
Then click here to download the exe: http://www.mediafire.com/?jlg2enkjdxn
Once downloaded, extract the files and hit hte S10FanCtrl.Exe. Once this program launches you should be able to control the fan. Keep in mind that if you lower the fan speed then it'll take upto 30 seconds before the S10 registers the change, so be patient.
I've only tested this on the latest BIOS 59. I am sure it will work on the 57 as well but the individual speeds might not work properly on that version. Please try it out and report back.
The only issue that I heard so far is that occasionally the fan will kick in regardless if in Manual/Smart Mode. Also the temp it shows may not be accurate. If you find any other issues please let me know what they are so I can attempt to fix them.
Once we have all the kinks worked out then I will release the source.
Heres a quick Video: http://www.youtube.com/watch?v=_PKl70ZgmFg
REMEMBER: USE PROGRAM AT YOUR OWN RISK!!! I AM NOT RESPONSIBLE FOR ANY DAMAGES THIS PROGRAM MIGHT CAUSE.
Application Use:
BIOS Controlled - Fan is controlled by the BIOS
Smart Mode - Fan is controlled based on the conifguration in the options. You can set the threshold here at what temp you want the fan to kick in...
Manual - Fan is controlled manually by the slider.
If you want to have the program startup automatically, then place a shortcut of the app in the PROGRAM FILES -> STARTUP folder. Then you may want to go to the options and make the application minimize at startup.
Edit:
It seems there are some issues with the app and the S10e or previous BIOS versions. Will post a fix asap.
The source code for S10FanControl is available here: http://www.mediafire.com/?sharekey=7a3fb99d33817c08c2b435915e8821d7e04e75f6e8ebb871, written in Visual Basic .NET 2008.
S10Fan - Windows
The second utility is a tool written by user slash:
Hi guys,
Well it looks like Lenovo dropped this matter after all. Anyway, I have here another fan controller to add to the bunch. I have been using it for some time now without any problems. It is for both S10 and S10e.
What the program does is basically the same as others. The S10's fan speed is controlled according to the ACPI thermal zone temperature. By over writing the values which resides at offset 50h of the EC register at an appropriate timing, the ACPI thermal zone temperature is over ridden. The program is written in C and uses WinIo created by Sysinternals. The GUI version is available now.
It should be noted that the fan speed temperature thresholds differs with BIOS version. For 14CN67WW and 14CW90WW the fan changes speed at temperatures 60c, 65c, 70c, and 80c. Furthermore, the BIOS will automatically shutdown the S10 if the temperature reaches 90c.
The program has a fail safe mechanism that automatically disables itself if the actual ACPI thermal zone temperature goes above 85c. This allows the BIOS to regain control and the fan will work as intended by Lenovo. If the temperature drops below 85c the program will take over control again.
To run the program, you will need administrative privileges.
Known working BIOS versions: 14cn58ww, 14cn60ww, 14cn67ww, 14cn90ww
The program will work with any BIOS version as long as the BIOS uses the 50h EC register readouts to control the fan.
build 2009.05.24
Higher priorities for EC commands.
Usage: The program will run in the system tray. Double click or right click and use the menu to open the program. To determine the BIOS temperature thresholds, use the 'Setup' button. To run at boot time, place a short cut in the startup folder.

Notebook Hardware Control - Windows
The third utility is a profile for Notebook Hardware Control. I've adapted it from a profile for the Lenovo N500 which I've found here: http://nhc.yourcopy.de/overview/. With the manual for creating the profiles that can be found here: http://www.notebook-treff.de/board/database/hilfsprogramme-f%C3%BCr-nhc/92-how-to-create-an-acpi-fil... I was able to change the ACPI commands to work on the S10(e).
Installation and setup is divided in two steps. The program Notebook Hardware Control (NHC) is available at http://www.pbus-167.com/. Install the program, but do not start it for now. Then you need my NHCConfig utility, available here: http://forum.eeepcnews.de/download/file.php?id=1476. It detects your model number and BIOS-version via WMI and writes a proper S10(e) profile to the NHC acpi directory. The GUI is German if you have a German Windows and English if not. Additional languages can be added.
After you've extracted the ZIP-file you have to start the nhcc.exe (requires .NET Framework 2.0). At first a message appears that you use the program at your own risk. Then you can choose if you want to apply your own settings (experts) or if you just want the program to run with my defaults (newbies). In the settings window you can see your system details on the left, you can set up your thresholds in the middle and you can set the fan speed you want on the right. Then click on execute.
Now start NHC. Go to the "Settings" tab and click on "Show all NHC options and settings". Then a few more tabs appear. Go to the "ACPI" tab and check if the "ACPI Control System" is running (if everything works, the message "ACPI Control System running" will appear, otherwise it says "ACPI control system is not yet configured for this system"). Now click on "Show ACPI Control System details".
Here you can change the temperature values the fan control depends on (the settings from NHCC are the default values). On the bottom of the window you can see the "Current CPU temperature". That is the value you have to deal with. In general it has a value of around 60°C. In the middle you can see four user editable temperature values. You can leave the values as they are if everything works. The on/off values are responsible for the temperatures at which the fan starts running and stops again after cooling the device. The level values are responsible for the fan speed, for example you can set the off_level higher to let the fan run all the time at the lowest level, if the values do not fit for your device or whatever.
You can switch between NHC and BIOS control by disabling or enabling the "ACPI Control System" or by closing NHC.
Q:
A:
With every utility it is possible that it takes some time until you see an effect after you've started the program. Any failure of the programs should be no big problem because the only thing that should happen is that the BIOS controls the fan. Another issue that might occur due to the way the fan is controlled is that the fan may start running for a very short time and it looks like the fan control has lost control. The fan should stop immediately or at least after a few seconds.
Keep in mind that running the S10(e) with a fan control means that the S10(e) has to deal with higher temperatures. That could mean that the device will not last for 10 years but only 9 years (who uses a netbook so long...?). In every case you need a tool for monitoring your cpu temperature. We know that especially Core Temp 0.99.5 and Real Temp 3.00 do a very good job. That is important because the temperature values you need to set up the fan control are different from the values reported by the cpu sensor, they are between 15°C and 20°C higher. A normal temperature reported by the monitoring should be around 40°C, with the NHC default values the fan starts running at 52°C and stops at 38°C.

Q:
A:
END using fan control
BEGINNING developing fan control
Controlling the S10(e)'s fan is a litte bit difficult because it looks like there is no way to control it directly. But it is possible to manipulate the temperature the BIOS fan control depends on. As long as the built-in fan control thinks that the cpu is cool enough the fan stays off. And that is exactly the point where we can attack.
The fan control depends on a field called RTMP in the memory of the embedded controller. It can be accessed via "_SB.PCI0.LPCB.EC0.ERAM", the offset of RTMP is 0x50 (hex) or 80 (dec). It is a direct I/O read/write. The complete NHC command for reading the value is: ACPI.FIELD.ReadByOffset("_SB.PCI0.LPCB.EC0.ERAM", ref value, 0x50, 8) with "value" as the variable which gets the value.
What program logic do you need? You need a timer or something else that conducts an always-refresh cycle. It sounds very easy: You read the value, manipulate it and write it back. And it is that easy, you just have to keep some things in mind.
This refresh has to be done very often. The procedure must be very thin and quick. Also the bus that is used to communicate with the EC is a problem, but since the S10e BIOS 66 it became a minor problem for me because it looks like the built-in fan control now depends on some kind of average value over the last few seconds and it doesn't really matter if one write-cycle is failing.
The read-event must be placed before the write-event. Otherwise you just read your manipulated value. The field is filled by the system regularly, so you just have to test if the read_value is different from the written_value, then you know that the field was filled with a "fresh" value. Like "if read_temperatue <> written_temperature then real_cpu_temperature = read_temperature else do nothing".
About the values you have to write back... you will have to test and play a bit. My experience is that you can select three fan levels, starting at 59°, 62° and 70° - at least with the NHC profile and my S10e it's like that. It's some trial 'n' error. My fan stays off at < 59°, but you should select a very low value for fan_off like 30°. In my opinion it switches off much faster the lower the written value is. But it's just a feeling, I haven't measured it.

Great opening post Carsten!
The latest bios:
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-71252 (BIOS 66)
The FSB can be reduced from 133MHz to 100MHz using SetFSB, this also reduces the heat:
http://www13.plala.or.jp/setfsb/
clockgen = SLG8SP513V
If you add a shortcut to the startup folder the program will start at startup. Under properties you can change the target to:
"C:\Program Files\SetFSB\setfsb.exe" -s100 -b1 -cg[SLG8SP513V] -w20
So it starts with a FSB of 100Mhz, in the background, with the right clock generator, after 20 seconds.

Does using a program like fan control damage my mbp?

I heard good things about this program so I downloaded it and it cools off the machine wonderfully. However, I was wondering if it caused damage to the machine as the fans are running at about 3 times what they ran before? Does anyone know anything about this? Thanks.

I would hazard a guess that if it did have anything to do with the failure of the hardware in any way, the manufacturer would void your warranty. Any repair needed would be chargeable.
Mac OS X, Boot Camp and the EFI firmware all have system settings created by the manufacturer. Using a program which alters their recommended settings or changes the behaviour of hardware devices within the machine, goes against the terms of the warranty.
I would ask Apple about Fan Control and get them to confirm that any damage which may be caused (or may not be caused) by a third party program willl not void your warranty.
In some respects, it's like overclocking a PC. Whilst it may be more beneficial to the system and provide better performance, the maufacturer of the computer can not be expected to repair something which has been damaged by the end user 'tweaking' settings to get better performance.
In the case of Fan Control, I have not used it so can not refer to the licence terms, the liability of possible damage done to the machine by using this program will either be at the end users own responsibility or the manufacturer of the software. This should be checked prior to installing and using the program.
I would suggest any program which alters the running of the machine will invalidate your warranty in the event of hardware failure.

848P Neo-LS Fan Control

As said - no control of the damn fans (Case/CPU) on my 848P Neo-LS. On the CoreCenter the button lits up on mouseover, but when pressed, nothin' happens (as said in manual, press to toggle user/auto modes for fan control).
Also CoreCenter doesn't show the Case fan's speed, but Northbridge (NB fan) fan's speed, which is obviously 0. Also NB temp is N/A. Also +12V is N/A. Also the FSB stays always at 101 Mhz, not 100. No overclocking done.
Today upgraded the CoreCenter to the most recent vers (1.7.0.0.), and the button doesn't lit up anymore...?
When I installed SpeedFan 4.17, it allows me to control the Case fan's speed from 2300 - 2700, but nothing more. Interesting.
CPU - Celeron 2.0
RAM - 256 MB Kingston
CPU Fan - OEM intel fan A80856-003
Case Fan - MJ 802512
Both fans with speed sensors, of course.
Should I update the bios?
Help somebody!

To be sure I opened the case and stopped the fans by hand (I don't use the corecenter prg - piece of crap), to see that i have mistaken both fans (in SpeedFan prg). The one who varies by 400 rpm is the Cpu fan.
Doooh.
The bios health screen doesn't show +12V at all - just aint there...
The MSI tech support sez - flash the bios, and if anything doesnt change, the CoreCell chip has gone (faulty, whatever).
Flashed the bios (1.0 - 1.9 now). No changes.

Proper Fan-Control by Lenovo?

Hello Everyone,
two weeks have passed since i got my Thinkpad L530 and for the most part i am happy with it. But there is one issue which gets on my nerves:
- the absolute annoying pulsing of the fan !!!
For me one of the most important reasons to buy this laptop were the good test-results about noise-emission and battery-duration, because i use this laptop for work. Therefore annoying fan-sounds are unacceptable.
To solve this issue i have comb through serveral forum-threads and finally found a solution for my Win7-OS with TPFanControl. But i also use Xubuntu and on linux there are currently no working fan-applications for the SL- / L- and some E-Series
What i have read about i'm not the only one with that problem and that issue seems known for ages....so my question is:
- WHY do we still have to use third-party programs to get this problem solved, with the risk of breaking our hardware? Is it that hard for lenovo to offer a proper fan-control for their devices?
Greetings, Christian W.

ArchSoarer: thanks. This thread is almost a zombie, but I have tried your "acpi_osi=Linux" boot command. It does make the fan operate correctly EXCEPT where one suspends or hibernates, in which case I still get fan problems. I have outlined the situation here on our wiki: http://wiki.archlinux.org/index.php/Tos … llite_L300 and have a link there to an attempt to fix the issue by disassembling the DSDT. I have yet to go any further and attempt to fix the DSDT errors in this laptop. For the moment, because Arch boot quite quickly I simply do not use hibernate or suspend on that laptop.

Fan control in notebooks

Hi all,
I am using Arch Linux since a few months, right after purchasing my new laptop, a Dell Precision M3800. Anyway I am a linux user since many years. I like very much the control that arch give to the user in terms of configuration possibility. My question is relate to fan control in notebooks. Even though I noticed this issue in my laptop now, I think similar observation holds also for other notebooks and linux distros. For fan control I use the fancontrol utility. Once properly configured, there is a min temperature value below which the cpu fan is off (default is 20 °C, I increased up to 45 °C) and a max temperature value (default is 55 °C and I placed 65 °C) above which the fan is running at full speed. The reason for the temperature limit changes is to emulate windows behavior in terms of noise and thermal handling. With a room temperature in the order of 25 °C, I get right after login a cpu temperature of about 35 °C. Then the temperature increases even in idle conditions up to the limit of 45 °C and then it is stabilized by the cpu fan. Chaning the temperature between 35 °C and 45 °C simply changes the time interval I have to wait until the cpu fan switches on and cpu temperature stabilizes with low load. The point is the the stable thermal situation produces a continuous switching of the fan state, let's say the fan is on for a few seconds every minute. The reason is that the fan switches off right after the cpu temperature falls below the value for which it turns on. Wouldn't be better to define two different temperatures for switching on and off? Let's say, fan on when temperature reaches 45 °C and off when it falls below 40 °C. Is there a way to do that with fancontrol or same other tool?
Thank you in advance.
Bye,
Luca

OP, what you're describing is called (at least in HVAC circles) hysteresis. You may be able to find some fan control scripts that support it (googling fan control + hysteresis), or just write one yourself. You can also control this behavior to some extent by adjusting fancontrol's polling behavior (the "INTERVAL" setting), but that has risks.
I think implementing hysteresis is not a particularly useful endeavor because PC temperatures can change 30 degrees or more in a few seconds when under load, which is completely unlike, say, a home thermostat where temp changes are much more gradual over time. Realistically, you should expect to always be running at least the CPU fan at some speed, and set your "turn off" temperature for it to room temperature. You can set different temperature set points for different fans, so you can have the CPU fan turning off at a lower temp, but have other fans off until the temp gets much higher.

Mac Pro Tower - Which Fans Cool All of What?

So I have a 2008, 2.8 GHz 8-core Mac Pro tower. I'm one of the many people who have problems with the fans. In my case, I can get really high fan speeds, and the problem seems to be due to a faulty temperature sensor. (Using iStat, it will sometimes show unreasonably high temps on a couple cores [or the heat sinks, apparently] immediately after turning it on, whether or not it's been off for awhile. Sometimes, it will even show negative temperatures, in which case the fans will really go into overdrive. Yes, I've already tried resetting the SMC and cleaning it out - nothing.)
What I've ended up doing so far is download Macs Fan Control and setting it to base the fan speeds off CPU temps that don't give faulty readings. This works really well for lowering the fan speed (and thus noise), but I understand that different fans cool parts of the system besides just the CPU. The fan names give basic descriptions, but not a lot of detail beyond that. I've been trying to find a diagram showing which fans cool which parts of the system, but I mostly get results about fan noise, or minimalist diagrams that don't tell me all I want to know. I'd like to make sure my settings are fairly optimal before I do anything intensive.
Can anyone help me with this?

I think you are "barking up the wrong tree".
The fans in the Mac Pro are controlled by Software in the System Management Controller. They make a feedback loop based on measured temperatures. If you are getting racing fans, that is probably based on Bad Temperature inputs. Fixing the temperature inputs is where you should place your energy. The fans are slaves in this process.
One possible exception: Most of the fans do have an RPM output indicator, which tells whether they are spinning properly. If the diagnostic indicates a MOT error, that is likely to be a Fan Motor that is not showing high RPMs at High speed settings, and may be defective. The power supply fans were designed by a different team, and may not have the same controls.
What SMC Fan Control and similar software allows you to do is put a new Floor under the fan speeds. They will spin faster at idle, and it is possible they may move up to even higher speeds more slowly. What is does NOT allow you to do is any actual reduction in minimum fan speeds, regardless of whether it allows you to set lower numbers.
When the numbers get extremely large, the magnitude bits overflow into what is sometimes considered the sign bit. That has no meaning in this context -- all numbers should be treated as positive numbers. That probably indicates they took a shortcut and used general-purpose routines for signed numbers that were lying around instead of writing more correct versions for positive numbers from scratch.

Fan control out of control in Windows 7 (x64)

Hi,
Anyone noticed that the fan control is not working correctly when running Windows 7 (x64) in Boot Camp? Under heavy load (100%) on both cpu cores, the thermal protection circuit actually kicks in due to the CPU cores reaching temperatures of 104 degrees (Celcius).

No, it seems like the built-in thermal protection manages to reduce the temperature quickly enough. I've downloaded an application named MacFan, which you can manually set the fan speed.

IStat Pro, SMC fan control and tempuratures

I've been watching the recent temp. problem threads with great interest.
My Imac has had no operational flaws *knock wood* but I'm a bit concerned with the temps which iStat Pro is reporting. For instance;
CPU A 103 F.
CPU diode 133 F.
Ambient 79 F.
Memory Control 112 F.
HD Bay 1 103 F.
Optical Drive 94 F.
WDC WD1600 etc etc, (the hard drive I presume), 99 F.
Most of these temps seem pretty darned high to me. OR, am I mistaken and they are not out of line?
Running SMC fan control at about 1/2 way up on all 3 sliders brings these temps down considerably, but I hate to "over rev" the fans and hasten their demise if I don't have to.
I'll appreciate your thoughts.

Extended fan control v.1.2

Can anyone tell me why this version of fan control does not detect sensors on the GPU despite having an apparent facility to do so? The temp for the GPU always reads zero degrees, which suggests it's not picking it up. As my macbook pro overheats when the capture window is open and working, I presume a lot of the heat is being generated by the GPU, so it would be useful to monitor and fan-control it.

Not all MBP models are supported. You'd better check with the maker of EFC:

But he'll probably tell you to get the source code and do the necessary modifications yourself.

Fan control questions

Hi
I have a mid 2008 2.8Ghz iMac with the stock 320 Gb HD and 4 Gb ram. It runs fine but I am worried about how hot the case gets at times, in particular the top left corner. I have iStat widget installed too which shows what I think are reasonable temps most of the time, but sometimes even after just everyday use (browsing etc...) some of the temps seem high (power supply is presently at 75c). The fan speeds don't seem to increase much at all from the factory minimums. I know about smc fan control and iMac fan control, but I have a couple of questions before I decide to use them.
1. Do you think I need to be worried about this?
2. What damage could I cause by running the fans harder?
3. If I use these utilities to push the fans harder than Apple recommends, will I void my Apple Care?
Looking forward to your answers
Paul

An utility like smcFanControl only changes the minimum fan speed setting. You are still running the fans well below its maximum capability. So the change is to the low end of the speed range, not the high end. You CAN set it high enough so that the minimum fan speed sounds like a small vacuum cleaner, but I would not set it that way for any length of time. I just tried it once to see what it sounded like with the fans running at a high speed (never heard them before). There is a max possible setting, so you can't set it to a crazy high number.
I use smcFanControl and have the fans set about 25% higher than the default speed. I still can't even hear them at that setting, so I figured I wasn't doing any harm and it may help my iMac run cooler (not that noticed any issues with heat).
I can't see how it would void AppleCare. Unless you set it to sound like a vacuum cleaner all the time (which would be really annoying), you are running the fans well within their normal operating range.
Note: The adjusted minimum fan speed is only in effect while smcFanControl is running in the background. It does not change any system or hardware settings. To go back to the default settings, just quit smcFanControl.

Fan control reset

hi how are you all i installed fan control and i forgot whats the factory fan settings as i have played around with it as aim a newbe to osx i have a macbook pro 13 i5 it wuold be great help if someone told the def seetings thank you

"remove the fan control program you installed."
And then reset the SMC, which will restore the default fan settings, in case simply removing Fan Control doesn't do it.

Fan Control Apps for MacPro 2.93 Mhz ....

Ok, I figured out how to disable Fan Control.
Now I only have smcFanControl installed. I can hear the fans running all the time now. Before I installed FanControl and smcFanControl I could rarely ever hear the fans, even during the hot summer.
I have the slider controls set to the minimum, but the fans still run constantly, and my room is in the 50s F.
I really don't think the fans should be running all the time. The only way I can find to stop this, is to delete smcFanControl.
Is there any other FanControl apps that will allow you to adjust the fan speeds so the fans will not run all the time?

the fans are suppose to and need to run.... all the time.
but normal default is 499/599 rpm
boosting the minimum default is useful
you can have and should have profiles for low-medium-high if you push and use your system heavily
sounds like you have
too many cooks - spoils the soup
corrupt preference file
are not using the SmcFanControl for intended purpose and as designed
most people do create multiple sets and have "my default' (for want of a name) @ 800-900 which improves air flow and thermal temps while still being quiet.
older FBDIMMs are HOT and helps keep them in the 60's *C or if you have a hot GPU and need more air flow
maybe you have dust or other issues or the Mac Pro is recycling its own hot exhaust
The thing to look at is WHAT is (hardware) Monitor showing for your TEMPS from the thermal sensors as to what is or is not normal
And reset the SMC / and delete the plist files used
Never use more than one background utilty for a job and keep all of such utilities to a MINIMUM for best fastest stable and for performance, they do add up, they do matter. "Less is more."

Re: Fan control that is able to overcome bios?

Hello everyone, I hope someone will help me in my attempt.
I have a Toshiba protege z830, and what I am trying to accomplish is to have a better control over the fan speed.
_My motivations are the following:_
Intel implemented a new Thermal Daemon for Linux -https://01.org/linux-thermal-daemon
which is able to play with the processor and enable advanced cooling methods that can drastically decrease the temperature.
This means that this daemon is able to force the processor under a certain temperature (at the expenses of the speed of course).
In my tests I was able to keep the temperature below 70 degrees in any circumstances (also high cpu load!) !!
_Here is where the problems start:_
The BIOS of the laptop starts the fan and sets a high speed after a while that the cpu stays at that temperature (69+).
Which means that after 2 minutes that the processor stays at 69/70 (AND DOES NOT INCREASE - due to thermal daemon), the fan kicks in at high speed
The result is quite useless, as the temperature decreases of 2 degrees only, and the fan keeps running uselessly.
Moreover that temperature is not harmful at all, and as soon as the CPU works less, the temperature decrease to 62!
_This is the problem:_
The fan does not decrease the speed (stays at HIGH SPEED) until the temperature reaches back 57/58 degrees for a certain period of time.
Which is totally useless, as the only way to achieve that is to close all the applications and wait.
But the temperature that I have with normal usage is around 64! (always using thermal daemon).
So my operational ranges are between 62 and 70 degrees, which is not harmful for the cpu, and the fan should stay on at LOW speed, instead of being at HIGH speed.
What I want to accomplish is that the fan stays at LOW speed when the temperature touches 70 degrees!
Because when it touches 70 degrees the fan runs at HIGH speed all the time, until it goes back to 58/59 degrees, and it is very unlikely to go below 62 with normal usage.

WHAT I TRIED:
- I found the tool toshset ( http://schwieters.org/toshset/ ) that with the modified toshiba_acpi (in the same page) is able to control the fan!! Hurray!!
It is possible to increase, decrease and turn the fan of. So apparently the problem seems solved.
No! Basically the tool works only IF the fan didn't start automatically before! In fact, if the fan is started automatically by the BIOS (as described above, 70 degrees, HIGH SPEED)
it is not possible to decrease the fan speed anymore!! the command "toshset -fan 0" will not stop or decrease the fan!!
So, my question is, if there is the possibility to overwrite the BIOS settings of the ranges when the fan starts/stop,
or if it is possible to have the control of the fan (with toshset) even when the bios starts it.
WHAT ELSE I TRIED:
- I also tried to read the DSDT table and find some values that are related to fan control, in order to modify them, but I am not experienced with that and can not find anything.
I hope I made myself clear and someone is able to help me in some way
Thank you in advance!
ps. If you think this is not the right forum/section or there are other places where i can ask this question please let me know

How to use fan control?

I just downloaded fan control because it sounds like a good idea to keep this puppy cool. What is a good setting that isn't going to be overkill. I don't want to compromise battery life too much. Anyone good with this program? This is for my MBP 15"

I see nothing there about "firmware" specifically. "...non-Apple products" could refer to any third-party software.
Some might argue that (e) applies, but these fan utilities don't "significantly alter functionality or capability". None allows settings below Apple's default 1000 rpm setting. Nor do they defeat the default Auto fan mode, which increases fan rpms as the temperature increases.
Most of the people passing on warranty scares are well meaning, but the facts don't support their contention.
These fan utilities in no way resemble the thermal paste mods that were kicking around these forums a few months back. Remember? And even then, some here maintained that mod (where you actually open the machine) did NOT void the warranty as long as there was no damage done.
Heck, Apple doesn't even warrant their own software!
