High GPU and CPU temps, TPM issues and other stuff on T43p

[Tantalus]

I recently obtained a Thinkpad T43p 2668-4DU from a family member coming back from Iraq. Now being in the desert for a while this thing has developed some heating issues among with other minor annoyances.

It has the 1.86ghz Pentium M CPU and its running pretty hot at 50-60c idle and 70-80c under full load, idk if this is normal or I should be worried. I read somepeople say this is normal and others say this is bad so IDK what to think.

The ATI Mobility Radeon X300 GPU also runs VERY hot. When idle it runs always at or near the same temp of the CPU but when running intensive graphic programs such as video games it can climb up to 95c.

This came with a badly pulsing fan so I ordered a replacement part, so the fan is clean and good. I used Arctic Silver 5 on the CPU and the GPU (as the replacement part didn't come with the funky cooling pad like the original), I know some people say u shouldn't put it on the GPU but I saw a 10c difference when puting the AS5 on.

The TPM Security Chip software is slow and all the firewalls I have tried like to make XP stick to the ''Communicating with security chip'' phase. Idk anyway around this but disabled the CSS8.2 software.

Also the left mouse clicker on the touchpad seems to be broken, I would order a new palm rest kit but I cannot find one that also has the fingerprint reader on it. The button presses down fine but it does nothing, anyone els have the same symptom?

So my questions is
What are the normal temperatures for a T43p to run at? And if these are horrible temps how can I improve/ properly cool the system?

And can anyone give me incite on the TPM issue?

Thanks for any replyers.

ps All my temp readings come from the TPFanControl program.

Hi from a fellow T43 buff!

To begin with, your machine is not a T43p, but a T43,although a very nice version of it...

Temperatures...that depends on quite a few things, especially on these machines...

a) How much RAM do you have in there?
b) How many processes are running when the machine is idle?
c) Have you replaced your fan with standard or long fan?

Honestly, you shouldn't see a T43 with these specs idling at more than 45 degrees C.

Broken buttons on palmrest are a common problem. Post a WTB ad in the forum's Marketplace and I'm sure someone will be able to help you out.

Hope this helps.

Set the CPU settings to "Adaptive" in the power manager. Idling should be below 50deg C.

Thanks for the quick replys!

It is using 1.5gb of PC-4400 ram I think

When its idle its just the default processes, Firewall, Antivirus, and tpfancontrol. The Fan I replaced it with is not the standard fan for my model, its somewhat diffrent but relatively same design/shape and a perfect fit to the board.

And there is no option in the bios to set the cpu to adaptive, theres just adaptive thermal management and its set to the defaults ''AC=Max Performance. Battery=Balanced"

And also when I first got this laptop it was idling at 90c due to the dusty fan, pockets of sand, gpu heatpad burnt, cpu thermal gel long gone lol.

And I thought this was a t43 because thats all it says on the computer but whenever I go to the lenovo website I can only find my model under the t43p menu xD left me a bit confused. well theres 1 problem out of the way lol.

Could the CPU and GPU be defective or got to hot in the desert and naturally heat up like this?

This is a ThinkVantage power management utility. T43 can take the newer standalone version without the Thinkpad Configuration utility.

The power manager utility is nice but it doesn't lower my temps without lowering performance . I want to get to regular temperatures while in max performance. idle 45c work load 55c gaming 60c

The NHC tool will help with the CPU temps. Do a search on it here, somebody posted a link on how to use it recently.

BTW, I think cpu load temp in the 60s is not unusual. There's not much you can do about GPU load temp (unless you do something to the heatsink), it will be far higher than the cpu (60c load would be very surprising...).

It might have been the thread How do you undervolt a T43 processor?...

Johan

[Tantalus]

I will have to try that, does anyone of a recomended setting for a t43 2668?

I suggest you just follow the guide (pointed to in my post above) in stead of relying on some "typical value" for your specific model CPU; this will give you the best result(s). Some idea of the voltages for the different multipliers may however be found in the (temp) sticky Managing Pentium-M Speed/Voltage with software.

PS: If you really want to kill the fan noise in/of your T43, see the thread T43 fan noise... really that bad?...!!

Woot, after the undervolting the cpu idle temp dropped from 55c to 46c, 9c. and goes to 55c under full load! This is more then acceptable for me. The NHC program is really nice as well.

6x: 0.700
8x: 0.764
9x: 0.796
10x: 0.860
11x: 0.940
12x: 0.972
13x: 1.004
14x: 1.020

are my voltages

after some more research I find that the issue with the security chip and firewalls is a non fixeable one lol

thanks for the info guys!
