Fan Control and Leopard

While I am happy with Leopard, it killed my Fan Control - now I face a roasting each time I use my MBP. Anyone know if this little gem will be updated for 10.5? Fan speeds of 1500rpm just don't cut it with a Core Duo.

Same here. Fan control from preferences quit working. I'd set it and when I open it back up again, it would be reset to 0. Also I don't know how I could get a -14360 rpm reading on both of my fans. Didn't know a fan could generate negative rpms...
My fix.. get the SMCfan Control and set you minimum speed for your fans... It also will give you the temperature of your computer. Works for now... I'd rather have the fan control feature back...

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.
Thanks; Jon

Fan control and PEACE

Hello, i recently erased by mistake tow folders from the startup items, fan control daemon and PEACE, i got the folders back but when the mac starts up i get this window telling me that there's a problem with those folders, how can i solve this?

If the SMC reset does not help, install istat menus:

Thing is i dont know how to enable CPU fan control/regulation ifd possible. Doesn't realy see anything anything in the mobo manual except mentioning AMD Cool’n’Quiet.
This fan i have installed is running fine but i thk it runs full speed all the time and that makes a lot of noise - not needed.
Thx for any advice/tip/hint

40 °C is fine. The minimum fan speed can be set is a % of the full capacity.
Start with 12.5% and if the fan needs to adjusts it's fan speed too often and it get's annoying you can raise it to 25% or more.

SMC fan control and default Mac settings

Hi,
I've started to play with setting fans speed manually on my Mac. So I installed Lobotomo FanControl 1.1 program. Then I've installed smcFanControl 2.1 for MBP.
However it seems that Lobotomo FC changed default minimal Mac settings and now in smc, the minimal possible rpm setting for fans is much higher that it was before I started to play around with changing fan speeds. So I think the original Apple settings for fans has been lost. How can I restore them?
Thanks,
Michal

I forgot to add that before installing smc I uninstalled Lobotomo Fan Control according to their website instructions.

Understanding Fan, Fan Control, and Heating Intel iMac

Greetings all, I'm a recent convert from the world of Windows to Mac and I've enjoyed it more than you can imagine. I'm a network admin at a major airport and have come to hate working on Windows during the day to working on Windows at home. Although, I wish no harm to Windows... they keep me with a job. >:)
I'm going to show my age here so don't laugh too much...
I have trouble understanding the heat fans inside my iMac.
I do play video games, namely WoW (Yes still a young'n).
When I first got my iMac (3 months ago) and started playing, I noticed the back panel would get extremely hot to the touch. I was worried because I never heard the fans kick up past their default speed.
I read the iMac handles heat by passing it to the back panel to allow for ambient air cooling. (Love the concept). But being a Windows user for years taught me to check my temps. I downloaded iStat Pro and my CPU while playing was at an alarming 60deg Centigrade.
I checked for blockages in airflow and checked to make sure my fans were running, which iStat also showed at 1200 RPMs @ 60deg. The machine idles at about 38-39deg. also 1200 RPMs
I did get this iMac used to cut costs, wiped it clean and put a fresh install of OSX.
My question is: **Are the speeds factory fixed and if not, at what temp do the Fans kick into overdrive and start pushing some air?** 60deg is dangerously hot in such a compact unit in my opinion.
note I did install and currently use smcFanControl to max out my fans when playing games to keep the temps down so I know the fan speeds can change manually, but shouldn't the firmware inside the computer auto adjust fan speeds based on their temp?
Message was edited by: SPuppy

Things have really changed... or the quality of the system is that much better than my old Shuttle Fragboxes. 60deg on my AthlonXP was within the limits but would spell premature age failure running it that hot. Its been a while since I had a true Intel product. When I was building PCs I couldn't afford them.
Its good to know that the fans will auto increase by the firmware. I suspected as much but just didn't know 100% so thanks for the response.
Ideally from a personal prespective I would like to keep my heat down below 59deg only because if the CPU is that hot, the ambient air inside the case is warm and I do not want premature failure of the bridges, HDD controller or any other component prone to heat failure. I'll take the smcFanControl off the startup processes and just manually switch it on and off when playing games. I can replace a fan cheaper than replacing the whole unit.
Thanks for your responses.

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.

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.

IdeaPad S12 - fan control

hello,
I'm the proud owner of a S12.
I've got the same problem as a lot of people with the S10: the loud fan. It's just running after a while and not switching off again. Is there anybody out there who could fix this problem with a little prog or using nhc as some did with the S10.
The programs from this forum for the S10 don't work on the S12.
Thanx a lot!!!

Hi, sorry no good news ...due S12 differences ... its not possible to control fan via NHC/NHC control for S10 got to work for the S12 ....as in this post Carsten says
No S12 Fan Control and other programs didnt work at all...

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.

Question re: fan replacement & smc fan control

hi all,
a few months back, i installed smc fan control and have been using it to run my fans at 6000rpm in an effort to keep my operating temps down (average now is about 115*F).
so, obviously, running my fans at 6000rpm for what is pretty much a continuous time will wear them down faster. my question:
will my fans be covered by apple care? i've got a plan valid for 3 years (i've had my MBP for about a year now). should i expect anything to happen to the fans within this timeframe?
thanks in advance

Hi blikebecks23,
When you start up your computer, it's already at 115 or it climbs to that temperature after normal usage? Personally, that's pretty normal operating temperature for these machines. I went to instal SMC Fan Control prior to responding and with my machine "idle" and having a few tabs open in Safari I'm sitting at 117 degrees and the fans at idle of about 2000rpm.
With that being said, I really don't see the need to run the 3rd party application, the built-in temperature monitoring logic for the machine is adequate enough to properly cool the unit.

Mac mini with SMC fan control

Just got a new mini a week ago and want to keep it in top running condition, is it worthwhile to use the smc fan control and if so what should I use for settings and any other recommendations.

If you want to keep it in top running condition you best leave this kind of control to the system.
If it is running too fast and noisy for you, then you can slow it down, but of course that will shorten it's life.

Uninstalling smc fan control

i installed smc fan control on my MBP in an effort to keep it cooler. some time after i installed it, i reinstalled my OS in an effort to address some other issues i was having. i didn't uninstall smc fan control before i reinstalled the OS (mostly because i didn't think/know it would be an issue). however, once i finished my reinstall, i noticed my fans never sped up past the 2000 rpm default, even when the computer started pushing into the 160-170 degree range (according to istat). i felt i had to reinstall smc fan control again in an effort to preserve my hardware. i feel now that the computer probably has a better sense of how to use its fans than i do, so i want to uninstall smc fan control and let the computer control its own fan speed. what is the best way to do this?

thanks for answering-- i took a look at this earlier today. i guess the only reason i am trying to find out how to do this is because the smc fan control seemed to have a lasting effect even after i reinstalled my system software (which i assumed would blank everything). do you think dragging it to the trash will take care of it when reinstalling did not?

MBP overheating, fan control apps not working

Hi, everyone.
I know there are tons of threads out there about MBPs overheating. I've read most of them, but I couldn't find one with my specific problem, so I'm posting.
I have a 13" unibody MBP I got in late 2009, running OSX 10.6.8. It has been reaching high temperatures (70+ degrees celsius) for about half a year. I installed smcFanControl and have been running my fan at high speed (6000+ rpm) consistently. It's noisy but it keeps my laptop cool, so I don't mind.
A couple of days ago my fan started making awful whining noises. I figured something was obstructing the blades, since my laptop does get pretty dusty in the places I use it. I'm planning to open it up and clean it out (with compressed air) once I get the time, because I figure it must be pretty dirty inside.
Now I have another problem, though. smcFanControl has stopped working: even though I set the fans to run at 6000+ rpm as usual, they are only running at at most 2000 rpm. I tried another app (Fan Control) and it doesn't work either. It's like the fan system management has stopped responding to the apps, or to the temperature of the laptop.
This means my laptop is getting frighteningly hot. It's reached 93 degrees celsius about fifteen minutes ago. Right now I'm not doing anything but typing this, I don't have any programs but Chrome and a word editor open in the background, and it's at 78.2 degrees celsius…but the fan is still running at only 811 rpm. I can't get it to go any higher with my fan control apps. I can barely feel the exhaust coming out of the back. Here's a screenshot: http://i.imgur.com/5nTBq.png
Is it possible this problem could be caused by a dusty fan, something obstructing the fan, obstructing the cooling passages in the laptop, etc? If so, will cleaning the laptop fix it? I don't know what else to do.
Thanks in advance for any advice.

The Apple Store genius bar will clean it for free. Since you got it in late 2009, it's about that time to get your fan checked out.
