Thinkpad Fan Noise Problem: Light at the End of the Tunnel

[dcouzin]

4th: the fan responds (under TPFC) to the temperature of that thermal sensor whichever finds the highest temperature.

Troubadix, you know this isn't true (at least as it will be understood by EchoFox. Under TPFC the fan responds to highest of the device tempertures minus their offsets. EchoFox needs to poke into the offsets in tpfancontrol.ini to answer his own question.

For some reason tpfancontrol will sometimes turn my fan off, thus causing my laptop to shut down due to heat. I've been trying to get tpfancontrol to stay on manual at speed 7, but it continues to revert back to smart mode 1 after a while, so I'm not sure exactly which mode tpfancontrol was in when this occurred. Needless to say, I didn't tell it to turn the fan off on purpose.

I'm on a W500 running Vista Business 64bit.

Below are my current settings. Any help on how to fix the fan issue and how to modify my settings to keep the fan running at 7 continuously would be most appreciated. The fan noise is negligible - my intention is for the program to keep my laptop as cool as possible.

Thanks!

Hello All

I have a Thinkpad t30, model 2366-KU1, with a 2.0ghz processor and 2 gig of RAM. When the BIOS controls the fan, it would run at high speed until a temperature of 36 degrees C was reached.

With TPFC v62 iIn smart mode 1, using the default settings below,the fan now shuts off at 60 degrees C (see below)

Level=60 0
Level=65 1
Level=75 3
Level=80 7
Level=90 64

Where the thinkpad used to cycle 5 minutes on, 5 minutes off to maintain the 36 degrees, setting, it now cycles approximately 1 minute on and 1 minute off (with the fan at level 1) to maintain the 60 degrees setting.

Here are some questions:

1. What is the safe operating temperature range for this processor?
2. Is the stock 36 degrees setting too aggressive?
3. Is there a better TPFC temperature level setting to use with this PC? The one minute on/one minute off with the 60 degrees set point vs 5 minutes on/5 minutes off set point of 36 degrees seems to be almost an equal trade-off. I'm not sure how much silence I am gaining - althought to be fair, TPFC it has only been on the PC for a day.

And as an aside, there really isn't much variance in noise levels of the fan between the 1 (4425 RPM) - 7 (4715 RPM) levels. It is insiginficant enough that you really cannot notice a lower fan volume at setting 1 vs setting 7.

Any ideas on this would be appreciated.

[yanggis]

Hi every, I install TPFanContral under Windows 7 64 bit. It works well. But One issue I have, my Event Logs are FILLED with this:
: The embedded controller (EC) returned data when none was requested. The BIOS might be trying to access the EC without synchronizing with the operating system. This data will be ignored. No further action is necessary; however, you should check with your computer manufacturer for an upgraded BIOS.
Source: ACPI......
Who can tell me how to fix it?
Thanks very much.

[mpcook]

I am running TPFancontrol, just using it to monitor my cpu temps. I noticed what I thought was a temperature spike and decided to keep track using the log function. I have some days of logs and can see on a rare occasion, an isolated 98 or 178 degree C reading. The fan speed does not waver, and the anomolous temp is just one entry, surrounded by normal temps (48 - 50). This is on a T400s, recently had MB replaced and just keepoing a watchful eye. Is it expected behavior to get an occasional random reading such as this, or does this mean my temp is truly spiking from 50 - 98 in 5 seconds, then back down again? Of course, the 178 degree reading doesn't seem possible, the CPU would have melted, right??

The other part to my question is that the slikes usually appear in the "switch" column, with no other spike in any other sensor. A few times, it did occur in the cpu column, but not switch. I anot sure what "switch" indicates.

Thakns for any advice.
Mike

I am having a peculiar problem with TPFancontrol version 0.62 on my brand new T510 running Windows 7 Home Premium where the BIOS keeps coming back and switch the fan on only for TPFancontrol to set it back to 0 when it comes up on top of its cycle time (5 seconds default value). I posted this question as a new topic at -
http://forum.thinkpads.com/viewtopic.php?f=27&t=91975

If anybody has seen anything similar or has any suggestions that might help make it work please reply.

Setting the CPU Power Management setting to ACTIVE in the Power Manager fixes the problem.

Installed v0.21 yesterday on R52, 1846. This is simply great, thanks a lot for the effort. The R52 is now almost as quiet as the HDD, being left in Level 1 most of the time (threshold 52° for level 2). The GPU does get a bit hotter than other components, otherwise it's like that for office + surfing on fan 1, ca. 3270 RPM.

CPU 45°C (0x78)
APS 43°C (0x79)
PCM 31°C (0x7a)
GPU 48°C (0x7b)
BAT 29°C (0x7c)
BAT 24°C (0x7e)
BUS 43°C (0xc0)
PCI 47°C (0xc1)
PWR 41°C (0xc2)

Suggestion for future: option for lowering the fan RPM below 3000 RPM. The level 1 is still very audible at sub 3300 RPM, but in my case, I can't leave it passive for too long. With lower RPM, the temperatures would still be in sub 50's except GPU.

[Colonel O'Neill]

The actual RPM at various fan states is controller set, so it's not exactly software changeable.

Also the latest version is v0.62:

My T43 fan is suffering from the "pulsating" problem which is well known.

When I was testing fan control solutions under Linux in the past I noticed that the ACPI fan control script (tp-fancontrol) has an ANTI-PULSE workaround which seemed to make the situation better. And it is very simple to implement, it just toggles the fan speed every few seconds from the one that is currently selected according to sensor temperatures to disengaged. This is from the script:

Code: Select all

...
setlevel disengaged # disengage briefly to fool embedded controller
sleep 0.5
...

My question to troubadix is if this workaround can be implemented under windows with his tpfancontrol?

I've recently had a problem with tpfancontrol that's specific to the W520. I wasn't sure whether to post here or in the W series forum, I elected the W series forum, but I thought I'd link to that conversation here just in case people weren't monitoring that forum but still familiar with tpfancontrol.

I'm running windows 7 professional 64 on a thinkpad t420s.

I've downloaded the lastest version of TPFanControl (tpfc_v062), but after I run setup and try to run the program, nothing happens for about 3 minutes, after which I get an error message:

"Error during initialization of Port Driver.
(tvicport.sys missing in app folder or failed to load)"

I've tried to run both setup and then run the program as administrator (I've even taken ownership of the TPFanControl folder in program files), but I'm still getting this error.

Please help!

[oxeimon]

nevermind, it looks like I just needed to restart.

Though, now that it runs, what's the little box at the bottom where you enter in numbers? It seems like it would correspond to Smart modes, but the number that's in there doesn't correspond to the Smart Mode that's checked when I rightclick the tray icon.

Hi there:) I'm trying to drop my temp on a T61 7665-12G(Lenovo) and get it to stay on 47-56C in idle/normal use with only a few things running. Now this is a core duo 2 T7300 systeme with a max temp of 100C.

When i got it a few days ago, it was installed with win 7 Enterprise 32bit, and in iddle / Normal use the temp got to be 75C, this worried me since I do know a bit about computers. So I remembered that Vista had a similar problem before the install of SP1. So I installed Sp1, and that helped a great deal the idle/normal temp went down to 63-67C.

So I will suggest to those running Vista or Win7 to install sp1 first to see what the temp is after that. Then you can use TPfancontrol thereafter:)

Also a small thing I noticed, that you Troubadix might want to look at, after closing the lid and thereby sending the laptop into sleep mode(not hibernation), then when I open the lid again I get the error of the port driver is not loaded. Tpfancontrol icon in systray is gone, but its running in the background. For now I'm not using it as an service, just the program.
This issue is easily solved by ending Tpfancontrol from taskmanager and restarting it.

Update 26.07.2011 - never mind the above, just disable UAC the you will have no problem with Tpfancontrol.

This is not a critic, by all means I think you prgram is a stroke of genius:) I just wish IBM/Lenovo would have implemented, the fan feature in the latest bios update.

To Troubadix or whoever wil answer this post, can you help me adjust the TPfancontrol.ini so that it will give me the temp I desire or is it dangerous for my fan?

Update 26.07.2011 - never mind the above, I got it set up now:) But I do like to know what the 128 switch do and how to get 4500rpm - could come in handy:)


Hope to hear from you soon:)

Is it posible to use TPFan on lenovo E520? Have somebody tryed on it??? I myself have e520, but I don't know, how I must set up the properities... Please could you help me?? I have got Thinkpad for first times...

[kstuart]

The instructions for tpfancontrol say the settings are for a T61.

Are these also appropriate for a T43 - and if not, is there a T43-appropriate .ini file somewhere?

( Since the original program was designed for a T43, it seems obvious that T43 users have already adjusted the settings to what would be optimal for a T43, so it seems pointless to do the same thing all over again. )

Also, the Power Manager settings have a "Fan Control" setting that can be changed between "Maximum Perforance" and "Balance All Settings". Does this setting have any effect on tpfancontrol and vice versa ?

Thanks for your help (and to everyone who has worked on the program).

[troubadix]

Are these also appropriate for a T43 ...?

[Bardamu]

Is TPFanControl incompatible with the L520?

My L520 seems to occasionally enter into sleep mode for no reason when using TPFanControl.

The laptop is not running overly hot, the battery is not running low and the laptop runs fine in every other regard.

Is this perhaps something I can fix myself (by changing a setting fx) or is it something more complex entirely?

Any help would be greatly appreciated!

I made a thread asking for help on the official Lenovo forums a while ago, but it seems noone knows a way to silence the fans on the L520 without issues.

This is my original thread.

[troubadix]

it's an incompatibility problem of lenovo software (powermanager, hotkeymanager) and TPFanControl, as the access to EmbededController is not coordinated, as I wrote in .ini

// advice for programmers: TPFanControl must acquire mutex named
// "Access_Thinkpad_EC" to get access to embedded controller

.... lenovo is neglecting this piece of advice

Thanks for replying so swiftly, troubadix!

Does this mean that simply uninstalling Lenovo powermanager and hotkeymanager will make TPFanControl work without the system randomly entering sleep mode?

Or are other Lenovo programs accessing the controller in an uncoordinated manner as well?

At this point I would gladly give up some Lenovo functionality for a quiet machine.

[kstuart]

Q:"Are these also appropriate for a T43 ...?" A:yesss

If you mean will the .ini file operate correctly as an .ini file when used with a T43, then that is correct.

If you mean that the temperature numbers in the .ini are appropriate for a T43, I am less sure.

The fan does not turn on, even to the lowest setting, until the bottom of the T43 is quite hot.

The .ini file has a comment inside it:

// ATTENTION: example temp values are for my T61, especially
// BluetoothEDR=1, SensorName5=no5, IgnoreSensors=no5 too
// temp levels 10 degrees centgrade higher than in T4x, R5x,
// change for your purposes.

When I lowered the Smart settings by 10, everything works fine.

SO, why is this not part of the step-by-step directions in readme.txt ??

PS And BTW, what is TPFanControl_ini.exe ??
