Fan Control Option in the EM

Can Lenovo enable the fan control option in the EM?
I know I can install other versions of the EM software but, I won't have the yellow color improvements found in the Yoga specific EM.

robik,

Fan control unlocked on the NX6600GT-VTD128

The bios edit that enabled temp monitoring, also enables fan control when you use Gainward ExpertTool.

Why not add that to the original thread?

Cannot see control options in the player

I have downloaded a free trail version of macromedia flash 6

hi
i was able to add control button like play ,pause ,stop with

Any idea???

Smc fan control or let the apple decides to control the fan?

intel core 2 duo mac book goes about the temperature of 54-60 C...hmm is that normal or should i use a third party application , just to minimized the heat?
1. does it wear out the fan fast if i run about 2,838 rpm or 3,500 rpm?
let me know guys!!..thanks in advance =]
or
should i keep the default settings, that apple would decide its own to minimized the heat?..as far as i know it only goes around 1,600 to 1,800 rpm and heat raise up to 56-62 C =[

I agree with lazypilot - its better for your notebook to keep it cool. Whether the fans spin at the default 1500rpm (Macbook 1st generation) or 1800rpm (C2D macbooks) - or 3000 rpm as set by the smcFanControl - makes really no difference in the life of the fan.
Many Macbook users use software that often stresses the CPU thus having the fans run at very high RPM's for extended periods of time - I doubt that a properly working fan would have any problems with this

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.
http://www.mediafire.com/file/njhz0icym2t/S10Fan.zip build 2009.05.23

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.

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.

Reset the smc to clean up after smc fan control?

i have been trying out smc fan control on my MBP to see if i can lessen the heat stress on it. i have removed smc fan control to let the computer handle its own fans (i'm starting to figure it knows more about its own fans than i do). however, now that it is gone, the fans seem stuck on 2000 rpm, even as the temp pushes into the 60-70 degree C range. would resetting the smc get my fans unstuck?

Your RPM and temperature readings seem perfectly normal to me.

I am looking for a Fan control utility for Toshiba laptops

Hello,
I am looking for a fan control utility for toshiba laptops (like i8kfangui for example).
anybody help...

Hi
Toshiba does not provide special too for the fan controlling.
Only the Toshiba Power saver is available on the driver page.
This utility controls the settings for CPU processing speed, cooling method, screen brightness, etc
Maybe its a option for you

MBP fan controle?

hi all...
In a topic of today we where talking about the fan-control option, but I lookt for it in my folders but, cant find it any where, so mabey some one can tel me where i can find this tool becaus my system is getten hot... lets say to hot for my standard... in this contorle it is posibel to ajust your fan-speed. so this option i like.

Lobotomo Fan Control

Ok got my MBP 2 days ago.. installed Lobotomo's Fan Control. Read on the internet that once you install it, it messes with Apple's preset fan-adjusting option in the firmware?
On the download page for this software, it even says "For safety, it leaves the original automatic fan speed control intact."...
I followed the instructions on their page for uninstall.. how do I make sure that Apple's original thing is still intact? Should I just goahead and use smc Fan Control?
I'm freaking out a little here... new 2500$ laptop lol

I don't know about outsmarting the engineers, but I know these little facts:
1. my new iMac 24" 2.8 Ghz with default settings is running in excess of 70 degrees centigrade for power supply (like 78 at high load) - and default fan control does not do anything about it - fan speed stays at lowest setting.
2. When I raise the lowest default fan speed a little (from 1200 to 1500 or 2000 for CPU fan, which also cools the power supply) - I manage to keep my power supply within 60 degrees at all times.
3. I don't have factual knowledge of how long my power supply is going to last if operated at 70C and above, but my guess is that keeping it below 60 WILL PROLONG ITS LIFE!
also remember that smart engineers only care about 1 year warranty period, while I care a bit further into the future!

Fan control problem on Z77A-G45 Gaming

Hi,
I've got this problem: I have Z77A-G45 gaming mobo and thermaltake water cooler (water 2.0 performer) on cpu and, by default this motherboard makes this cooler work with full 2000 rpm, but if I open the msi utility program "Control center" and go in "Green power" tab and use "CPU fan control" it makes cooler to run normally with 850 rpm. But problem is, when I turn off or restart PC, it starts again with 2000rpm and I need to open that "Control center" again and click check "Cpu fan control" to make cooler work normally. So what is solution to this problem? How to make it remember "cpu fan control" option marked? I don't want to start this application manually everytime I boot my computer.

Try entering bios and enable cpu smartfan and save on exit.

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.

Network Variables Custom Control Option Disabled

Hi all,
I am trying to create a network variable in a cRIO project using a predefined custom control.. I have done this hundreds of times before in other projects.. For some reason the "from custom control" option at the bottom of the data type dropdown list is disabled....!!!
I am sure this is something very simple but I am well and truly stuck now.. Could it be that I am not yet connected to my RIO?? I have not enabled the network connection yet..

Solved!
Go to Solution.

Well,
I have now found the solution.. This is a bug.. Just shut down labview (completely, not just the project) and restart it and voila...the option awakes...

Dell Vostro fan control mystery

When I first installed Arch on my Vostro laptop back in October '12, I had to run the i8kmon and i8kutils to get the fan control to work. Without it, the fan was blasting at full speed all the time, no matter what the CPU temperature was.
However, this week I started noticing odd behavior in my fan control, in that the i8kmon service would start, but fail silently and the fan would remain off, no matter the temperature (not good). Here's the mystery: I disabled the i8kmon.service and since then my fan control is now BETTER then ever! The fan speed gradually increases and decreases based on system load, it's perfect.
Does anyone know what may be going on here? Perhaps the 3.8 kernel now supports this fan without special drivers? Of course, it could have been from earlier than 3.8, but I always had i8kmon running...?

Use the special key combo - It works on most Dell systems
Shift + FN + 1 5 3 2 4 from a VGA tty console - three lights will flash and one remain flashing. This enables a special Thermal management settings screen. Press FN + R to access it, you can change the fan speed, adjust the throttling and so on.
I need to set the fan speeds to 6000 and 5000 RPM, after which i8kfan 2 2 will reach max speed. Don't use this mode from within X, the system suspends everything else when in that mode and it goes into a VGA console, so things can screw up with the Wifi and the video adapter sometimes.

Fan Control, firmware restore

I recently installed Lobotomo Software's Fan Control 1.2, but have since read (and seen) that it apparently modifies firmware to disable SpeedStep - with the result that the MBP no longer modifies fan speed once I uninstall Fan Control, while CPU speed remains constant at 2.2 GHz even when the AC adapter is plugged out & 'energy saving' selected.
First I tried the uninstall procedure on www.lobotomo.com (delete files, reset SMC). No success. Then I tried the Fw Restore CD (1.6 and 1.7), but neither seems to work. I've followed the instructions on Apple's FW Restore page, but the MBP doesn't behave the way they say it would - the sleep LED blinks rapidly, followed by the long beep, but even with the Fw Restore CD inserted it just boots as normal.
The Fw version is MBP31.0070.B07. Was I just using the wrong Fw CD? Is there anything newer than 1.7 anyway? Is there another way to reset the Fw, or remove Fan Control's modifications?
Any help would be much appreciated.

Right. Gathered as much from researching the problem, but thanks, will keep this in mind for the future.
Anyway, to update the fan speed issue - apparently it did not mess with SpeedStep, at any rate not the part of it that controls CPU speed (checked via MiniStat). But fans still won't kick in without Fan Control (which I'd really hate to have to install again, seeing how miserably it seems to work).
I've been monitoring fan speed for the past hour or so, and installed SMC Fan Control as a stop-gap, but apparently when left at default (2000 rpm) fans won't kick in until CPU temp is in the high 70's C. I started a couple of CPU-intensive (Parallels, Photoshop) apps just to check, and got a growl note (presumably from SMC Fan Control) telling me the Mac was too hot and that I needed to close some apps), at which point I chickened out and used SMC to bring the fans to 4000 rpm...
Is such behaviour normal? I mean, does the system generally wait for the temperature to get that high before spinning the fans up? Have I screwed up my MPB beyond repair?

17" unibody: temperature/fan control buggy. again every book affected?!

i've heard that the new 17" books are also affected by the buggy smc fan control just like the 15" late 08 MBP! anyone can confirm this? so has anyone tested his new MBP (especially the 2.93GHz version) just like described in this thread?:
http://discussions.apple.com/thread.jspa?threadID=1823105&start=0&tstart=15
1. put your book to sleep and wake it up
2. start two instances of 'yes > /dev/null' in the terminal
3. check the temps and the fan speed with the istat pro widget
4. the fans won't speed up (speed stucks @ 2k rpm) and the CPU temp will reach >105°C / 221°F

I have seen laptops with intel cpus from every single brand have problems with temp reporting and then fan control on the book. HP, Dell, Lenovo, Apple, its everywhere! millions of models! If you panic everytime you have to adjust the fans yourself, you'll be in a panic for the rest of your laptop-using life.
Forget it and up the fans with SMC fan control!
and again, read the linked thread.
if you reset the smc, the fan control is ok. if you heat up the cpu the second time or you put your MBP to sleep and wake it up the fan control is strangely faulty! the intel cpu isn't reporting the temperature wrong!
and a very important thing i want to add: as soon as the cpu reaches ~105°C it underclocks itself! this state lasts up to 5mins until the fans slowly kick in!
