Heatsink fan runs in Passive System Cooling policy (Thinkvantage Power Manager 3.62)

Hi all.
I have a T60 model 2008 thinkpad, and its running on Windows 7. All was going well. Two weeks ago, I noticed that it would get a little hotter than usual. As it had been a year since I opened it, I decided to service it. I used the manual and opened up the laptop, gently removed the heatsink, used compressed air to remove the dust and reinstalled it. I also put a pea drop of thermal paste on the CPU for good measure. Put it all back together and it is running significantly cooler.
I usually use my laptop in Maximum battery mode when unplugged, and for that I keep the system cooling policy to passive. My question is, should the fan be running in that mode? Because ever since I serviced it, my heat sink fan runs in passive mode as well, (never noticed it running before in passive mode) and I think it is making my battery run time decrease.
Any ideas on how to fix this or if this is normal will be appreciated. Have a good day all.
- Ibrahim.
Solved!
Go to Solution.

In passive mode the threshold temperature for when fan kicks in is increased, so fan would spin up to the max speed only when it reaches a higher temperature. But the fan will still kick in.
When you put back the heatsink, make sure the thermal paste is applied properly, not too much just enough to have a thin layer on the CPU.

Powercfg (System Cooling Policy)

I'd like to create a PowerShell script that will only create the setting for Power Cooling Policy where the Battery needs to be set to Passive and Plugged in to Active and only work on a laptop the script will also run on a desktop but I don't want
it run on a Desktop I want the desktop to keep its settings.
this command hasn't been working:

Fan runs (nearly) fullspeed ALWAYS - XPS l502x

Hey!
After trying everything i end up really desperate and now count on your help.
Following is my Problem:
I changed my HDD for an SSD two days ago after having my XPS L502x for nearly three years now.
Everything works fine with the SSD, it runs super fast, i installed Windows 8.1 (before that i had 7). So i didn´t clone my old one, just started over with the SSD.
Now my fan (blowing out on the left side) runs always without any breaks at constantly about 90% power. It begins just the moment i start the laptop, so already before the dell-logo and without even booting Windows.
Here is what i already tried without any change of fan activity:
- installing all kinds of drivers, from Dell, for my Nvidia, every single one i found for the parts of my laptop (also removing and installing graphic drivers)
- booting Ubuntu from a DVD
- updating to the newest BIOS, downgrading to an older one, trying a few settings in the BIOS
- using different diagnostic tools from Dell (as well speed fan), all in the end telling me they can´t access the fan
- dis- and enable TRIM
- changing to my old Seagate HDD (to check whether i might have damaged some temperature sensor from the fan when i disassembled the laptop partly to reach the HDD), and here comes something interesting: the first time i changed back to the old HDD the fan worked just well again, totally normal with spikes when getting hot, but most of the time silent. Then i changed the original HDD (suspecting it might have some kind of temperature sensor or other thing to communicate with the fan) for another HDD from HGST, which made the fan go crazy again. Changing back to the SSD it didn´t work as well, but then i tried the original again to look for software and suddenly it didn´t even work with that one anymore...
So it could be, that i damaged somehow something of the fan when changing the hard disk, but i can´t really believe that, having in mind that building in the original hard disk again for the first time made the fan work normally. I´m believing it has to do something with the software, though i have no more ideas what it could be.
My System:
The old HDD is a Seagate 750GB Momentus.
The unknown device is the ST Microelectronics DE351DL Motion Sensor, Windows 8 just doesn´t support the drivers given.
BIOS right now is the A12 (i did the downgrade with A6)
If you need anymore information just let me know.
I´m happy about any advice, guess and help you guys have for me!
Greetings
Lukas
PS: Also, if you don´t understand something because of my English ask me or talk German to me :)

Hi Anamandy,
There are no settings in BIOS that can be changed to control the functionality of the fan. However, there are couple of options you could try within windows.
Go to control panel -> power options -> change plan settings -> change advanced power settings -> processor power management -> system cooling policy -> on battery and plugged in -> change to passive and apply. Check this link for more info - http://bit.ly/1OPjs9m
You could also download and run Speedfan - http://www.almico.com/sfdownload.php- however this application does not detect the fans on all system models.
You could also change the optimus settings to auto in nvidia control panel - http://bit.ly/1Gg5CYU- you could do this if you do not use the system for gaming / high end graphical usage.
My suggestion is to clean the air vents and if you are able to open up the system, then clean the fan blades. This ideally might fix the issue.
If the system is under warranty, then please send me the service tag of the system and your contact details through a private conversation. Or you could use twitter - @dellcarespro
- we can DM through twitter and help you fix the issue.
Keep us updated.

Satellite C55-PSCG8E FAN running fast when pluged in

Hi There,
My laptop's FAN is running really fast and loudly when plugged in AC power source.
However the FAN runs quietly when the battery is used.
The laptop is new and so far only the antivirus application is running.
Is this a normal behavior or an issue ?
Normally a FAN run as fast when the CPU is hot and many applications are running.
regards,

Hi Yassine
Dont be worried about this notebook behavior this is nothing unusual
The reason why the fan is running faster when AC adaptor is connected this very simple: the Windows system use different settings using the battery or mains power.
Using battery mode, the system is configured differently in order to save battery power and to increase notebook working time.
You can change the settings in control panel -> power options.
Here you will find different power plans
Click on the current power plant and check the Change Advanced power settings.
Here you would find the settings for cooling method (sometimes its placed within the Toshiba power saver or Processor power management).
There you can change System cooling policy: you will choose either passive or active
Maybe this FAQ could be interesting for you:

Macbook Pro Fans Running At Full Speed When Macbook is Very Cooool

Ok, So now i'm pretty sick of the fan noise.
I've done PRAM reset, Power Management Reset to no luck.
So i decided to do some experiments.
As soon as the computer starts, Fans spool up to 6,000 and stay there. CPU Temp 42 Degrees Celsius.
Now My CPU temp does pretty well staying there. In Activity Monitor, No Processes of what so ever. Computer idles at 99% and only 1% being used by system.
So i decided to put the computer in the fridge. As soon as the temps went down 5 Degrees, to like 30 to 35 Degree Celsius, Fans idled at 2000 and as soon as the CPU temp is 40 Degrees, Fans spooled up and kept going all the way back to 6,000.
See as the temp drops on the computer, the fans do slow back down as the CPU temp drops from 40 to 35.
I called apple and the apple tech i talked to said that it seems the fan specs might be set out of whack. Meaning, the temps as which the monitor spools up the fans is set to low. He said it should be around 50 to 60 even 70 Degrees Celsius's before fans should spool up. He said the problem isn't the monitoring system since it does appear to be slowing down and speeding up the fans between 30 to 40 Degrees but it's spooling the fans up and to low of a temp than needed. He told me to take it to a Mac Genius sometime soon.
so before i do that, any apple geniuses what to take a stab on whats wrong and why it's doing this?

My fan runs continually, BUT, with several monitors watching core AND fan exhaust temps I have noticed something strange. The core indicates 28C while the exhaust jumps from 42C DOWN to -128C and then the fan races. While this is keeping the book cool as a cucumber it is driving my wife and now me up the wall. NO I don't have any hung processes. NO the CPU is not caught in a cycle requiring massive computing power. Regardless of the temp the fan runs at the 6200RPM max. Zapping PRAM and resetting the System Management will soon be followed by gravity resetting through my 2nd story apartment window. One way or another this needs to stop!

Satellite R830-182 - cooling fan runs permanently

Hi,
I have just purchased a R830-182. The fans runs 100% of the time, starting with the moment I boot up. Is this right, I expect the fan on a laptop to kick in when the CPU reaches a certain temperature? This is annoying as it is fairly noisy. Have also tried running the laptop at lowest possible power - no software open, WIFI off, battery saver power management, screen brightness turned down etc to no avail.
Anyone out there with the same model know if this is an issue or just how this laptop it is supposed to work?

I agree with as***: change the cooling mode in Win 7 power management
+How to handle the power managment features of Windows 7+
http://aps2.toshiba-tro.de/kb0/HTD12017W0001R01.htm
it seems that your notebook has not been equipped with an fingerprint. But check if the fingerprint software is installed. If its installed, then remove this from the system.
Furthermore I recommend changing some BIOS settings:

Dynamic CPU frequency mode (not sure about the available options but try different posibilites)

Cooling fan runs constantly on Tecra A3

I have a Tecra A3 an my fans runs constantly, even when idleing, and it has done this since i got it (about 18 months ago). It also runs at a constant rate, and it's just like hear Arnold talk - very annoying. Sometimes one (?) of the fans stopp running for just a couple a seconds, and then it starts again, back to the same speed. I've had the computer in for repairs, and they changed the fan and cleand the cooling system, but this didn't make things better, well, okay, I got rid of the ratteling sound, but that was all!
I've tried everything i can think of, currently I'm running the computer fixed on the lowest setting for the processor speed and battery optimized cooling by the help of the Power Saver utility, but it doesn't seem to help at all. I also tried setting the processor speed to low in the BIOS setup, this made some difference, and the fan stayed of for periods of up to 30 seconds (!), bur the performance of the computers performance was horrible with these settings so I had to change it back to dynamic processor speed.
As for the the temeratures i get at temperature of about 36-37 degrees celsius (95-97 degrees Fahrenheit) for the HD temperature (using speedfan). So theres no problems with overheating (?). This leads me to believe that this might be due to a bug in the software. I'm currently using a norwegian install of Windows XP with SP2, it's a custom install, provided by my university (my computer is a student PC bought through the university).
So, can anyone help my make my computer quiet, like normal, sane computers ?!
Thanks in advance for any help!

Hello Stigs
I use Tecra notebook (M1) for years and I can tell you that this model is really one of quietest notebooks I know but it is definitely no utterly quiet and cooling fan runs almost constantly but on slowest level. I know that it has nothing with your problem but I just want to say that quietest notebook produces noises.
Reading your posting I can just say that you are probably right when you say that it can not be because of hardware because the notebook temperature is OK and there is no sign of overheating. The fact is that all newer notebooks are louder than some old models and Tecra A3 is one of them and unfortunately there is no much to do. As far as I know nobody has reported about any software bug till now. Many bugs are fixed by BIOS updates and all I can recommend you, is to check if new BIOS version is available and see if this can help. Please before you start with BIOS update read carefully Instructions how to do this.
Good luck!

Cooling fan runs too much

I've had my MacBook for about 5 months. Recently (the past month or so) I've noticed the cooling fan running a a lot. Even if it's in a cool environment, sitting on a desktop, it will sometimes run constantly. There are only a couple of applications open and no CD/DVD in the drive. This problem is random; for instance, today it started after I restarted my machine. It's been running non-stop for a half hour now. I do regular updates, including the latest firmware update last week. Any ideas?

I'm not surprised. Last time mine did it is was a printjob that was running. I didn't try to print but something I looked at or did caused it to start.
Go back into activity monitor and high light the process. Then click the stop sign looking icon to quit that process.

Satellite C55-A - after BIOS update cooling fan runs faster

Hello,
I was informed by Toshiba application that new BIOS version is available I confirmed it and BIOS was updated. Now I have problem. Cooling fan runs faster than before and it is very annoying.
Can I find older BIOS version somewhere and roll it back? I don't need it if it doesn't work properly.
Now I have version 1.40. Is there some solution for this new version?
Message was edited: posting has been translated

Toshiba EU driver page provides only the latest BIOS version.
Furthermore the BIOS downgrade isnt possible using the win-bases BIOS update.
In order to downgrade the BIOS on Toshiba unit, you will need to use the traditional BIOS update method which requires special BIOS version. This is available only for authorized service provider.
At the other hand there must be an serious reason why the cooling module run faster.
Maybe the cooling method has been improved in new BIOS just to ensure that internal parts would be cooled down properly.
Its just an assumption but I think it makes sense
By the way: after each BIOS update, you should load the BIOS default settings and should save the changes. If you havent done this in the past, do it

Hi vashx --
The Cooler Master Aero 4 gets an A+ from this happy owner.
See it at:
http://phamcomputer.safeshopper.com/36/727.htm?938
I own one, and can tell you it works great. It keeps the CPU temperature right around 40 deg C (+/- 5 deg C), consistently.
Prior to using it, the stock Intel HSF was installed. I saw temperatures around 50 deg C quite often.
Note: there are two versions of the Aero 4: a "lite" version, which uses Aluminum as the heatsink material, and a regular version, which uses Copper as the heatsink material. I own the regular version.
And yes - there are other HSF units out there, made by other companies, which work great too.
Why did I choose the Aero 4? Because of the unique way the fan was mounted on the heatsink. It really does work.
Oh, and I did decide to use Arctic Silver III (and I meticulously followed their application directions.) Unfortunately, I don't have any comparison figures to reference, so I'm unsure how much it helps. I am assuming, though, it did not hurt to use it

BarkingDog

Stock heatsink+fan question

Hello,
I have an FX55 CPU which was originally installed with the stock HSF.
I needed to remove the HSF and now i want to put it back.The question is:can I use a cooling compound (arctic silver etc) with the stock HSF or must I use the same solid product which was originally on the HSF?

I am not by my system at the moment (using the crap lump they call a pc at work )
But as I remember, no, the release lever is right alongside the ZIF, which is totally obscured by the stock heatsink/fan, which fits snugly into the plastic 'frame' which the ZIF is in.
Care is the main item here, and possible, run the system just before you remove it, and the processor will be hot and the pad softer, I did mine cold and was lucky it didn't leave a leg behind
Was all my fault anyway, replaced my 350 W power supply with a 500 W cheapo from Ebuyer (£14-99), the powersupply looked good, but fried itself (nice smell of burning plastic) and took my motherboard with it (but luckily my chip, memory, graphics and other attached bits survived ! )

Black Screen After Fans Run at Maximum

Hello,
I inherited an iMac and it an issue. It boots up fine but within the first five minutes the fans start to slowly ramp up to full speed. After about five to ten minutes of the fans running at full speed the screen goes black and I lose control of the computer. I cannot see anything on the screen, not even the cursor moving. I am also not able to shut down the computer using keyboard shortcuts. I have to hold down the power button.
The computer actually is still working to some degree after the screen goes blank because I have had a video playing from a USB stick and I could still hear the audio after the screen blacked out. I once had a Youtube video playing via the WiFi and when the screen went black the sound stopped.
I took the computer apart thinking that maybe it was full of dust. There was very little dust and blowing it out did not make a difference.
I have done a SMC reset and and a NVRAM reset and neither made a difference.
I installed a temperature monitor and the following is the output in degrees F a little before the computer goes to a black screen:
AC/DC Supply: 99
Airport Card: 141
Ambient Air: 76
CPU Heatsink: 93
GPU Die: 262
GPU Heatsink: 254
GPU Proximity: 223
Hard Drive Body: 102
LCD Proximity 94
Misc: 103
Optical Drive: 99
When the computer is running properly all four diagnostic LEDs on the logic board are lit. When the display goes black LED number 4 turns off leaving the other 3 on. Based on the Mac diagnostic instructions, if the fourth LED is off the issue is with the LCD panel or there is no video signal being generated.
I suspect that the video card is not working properly due to the high temperatures. It looks like the heat from the die is making it to the heatsink so I think that the thermal paste on the GPU is okay.
The computer is an iMac model EMC2134
OS X 10.8.5
24" Core 2 Duo with ATI Radeon HD2600 256 MB video card
I also ran EtreCheck and the output is below.
I would like to repair the computer even though it is old. I however do not want to bring it in to a repair shop. What do you think is the issue and what leads you to that conclusion?
Thank you,
jbr

As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosened. Reinstall the RAM grille. Plug in the keyboard and mouse if not bluetooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET

Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.
