Thinkpads Forum

Hey, just got tpfancontrol up and running and it works fine, it's just that I'm worried because while everything else on my computer is reading a realistic temperture, my GPU seems to be running at 73C right now! Is this a problem with the program or do I have a problem here? FYI, the temperture is fluctuating. Any help appreciated. Thanks.

I really doubt that this given temp is real one. Even in the morning when I turn on my T60 I get 50°C while all other components are around 30°C. There might something wrong because those temp doesn't make sense at all.

What Thinkpad model do you have? TP FCU was originally designed and prototyped with a T43 which has 9 temperature sensors and a given layout for them. Not all Thinkpads have that and might have a different physical layout of the temp probes on the planar and/or different ways of reporting the values.

Makes sense, this is a T60. Wish there was an updated version of this, though, it's quite useful. The fan control works, though.

i've noticed the gpu temps are really high too.

im ignoring the gpu sensor for the time being, nhc's acpi (modified the t43p acpi file) displays it as 70c which causes no end of problems for me.

and thats with watching a movie, i hate to see how high nhc/fancontrol reports the temp after a session of hard gaming!

Hi guys,

sorry to ask this, might be stupid, but can fancontrol even read the GPU temp and display it?
And if it can do that what do I need to do to let it display the temp?

Thanks

I am interested in this as well.

I downloaded the 0.19 svc version which was desigened for a T60p so I suppose it is reading the temps correctly.

However right now the fans are adjusted according to the GPU and I am pretty sure that is not right, right?

Any body knows how to change that?

Here are my readings:

CPU 49°C (0x78)
HDD 35°C (0x79)
HDD 38°C (0x7a)
GPU 64°C (0x7b)
BAT 50°C (0x7c)
BAT 31°C (0x7e)
XC0 40°C (0xc0)
XC1 46°C (0xc1)
XC2 49°C (0xc2)

Can't see anything that would harm your TP. Your values look normal w/o any reason to fear


Brgds, Torsten.

My Thinkpad R50p has an overheating problem. It powers off when I run graphics intensive applications or games. I sent it to IBM a week ago, they replaced the CPU fan and said it was fixed. However, the problem still occurs.

I have found the game Crimsonland (link to download page) to be a good test-bench. After starting the game in 1024x768 windowed mode, I leave it running on the menu selection screen, and Fan Control in a separate window.

The GPU was at 63°C before I started the test.
After 1 min: CPU 60°C, GPU 100°C.
After 2 min: CPU 75°C, GPU 111°C
After 3 min: CPU 83°C, GPU 115°C
After 3m30s: CPU 54°C, GPU 116°C --> The fan had over 5000 RPM for a little while, then went back to the normal 3800 RPM. GPU temp was not affected.
After 4 min: CPU 50°C, GPU 117°C

At 4 minutes, 15 seconds the machine powered off. I have never seen the temp go over 117°C, so I believe that's the threshold.

The central part of the machine is fairly hot to the touch, you can even feel the keyboard getting hot.

This happens with all graphics applications & games. I placed the machine on its side under the air-con unit, and got these results:

After 2 min: 100°C
After 3 min: 107°C
After 4 min: 113°C
After 5 min: fluctuated between 115°C and 116°C for an hour before I stopped the test.

The CPU was at about 47°C.

From reading other posts, this does not seem to be normal behaviour. I would be happy if anyone else ran my quick test and reported their results.

Thanks

Hi ahe:

I'm sure your R50p uses the same graphic chip as a T41p/T42p (128MB Mobility FireGL T2) which generates a lot of heat. My guess it that your machine should be fitted with a Long Fan Assembly to cool down your GPU and CPU. I haven't found on eBay hatsinks specifically designed for the R50p series protruding the heatpipe to the GPU. My T42p when new also had problems because came equipped with the short fan.

I will test Crimsonland and post my results.
Could you post your machine type.

You should get ispropyl alcohol, some AS5, and open up the machine to see which kind of heatsink you have.
Probably another user could be more helpful if he/she owns a R50p. I'm pretty sure your GPU should be in contact with the heatsink.

Thanks for your reply, benottomex. The model number is 1832-22M, if that's what you meant. It has the 128Mb FireGL T2 chip. I put the system specs in my signature. It has the 13N5182 fan and heatsink, which I believe was fitted on the T41 too.

The machine was advertised as a "mobile workstation" or something like it, so I expected it to work with 3D-Studio, games and other applications without breaking down. I have been able to use and develop graphically intensive applications by putting it under the air-con while it was processing, but this is obviously a sub-standard solution. Sometimes it overheats then too. IBM has had to replace the system board twice, which I'm guessing was caused by the heat.

Initially, IBM suggested it was a software problem, so I restored everything from the Preloaded area. I tried playing some games without upgrading to XP SP2, without upgrading any drivers, after upgrading to XP SP2, after upgrading drivers, in Linux, anything I could think of. But it always failed.

I'm not sure what I hoped was the result of these posts, but maybe I would get a more solid argument to persuade IBM support that this is not acceptable.

I will try to modify the machine myself, if I'm unable to get IBM to fix it.

edit: grammar

I'm a bit surprised nobody else thought this was an interesting experiment, considering all the talk about temperatures and fans in the past. Anyway, I got my dad to do it with his T41, and the GPU temp never rose above 81°C.

1 min CPU 65 GPU 73
2 min CPU 69 GPU 76
3 min CPU 71 GPU 79
4 min CPU 73 GPU 79
5 min CPU 73 GPU 80
6 min CPU 74 GPU 81

Quite a different progression than on my machine.

IBM is picking up the machine again today. I hope they're able to fix it somehow.

I got the machine back from IBM on Monday, and they said they had done extensive testing. The first thing I did was to run my test again (which I included with the laptop the previous time I sent it in). And it failed after 8 minutes and 20 seconds. Somewhat improved from the 4 minutes and 15 seconds, but still unusable.

I found another standard test bench that fries the gpu quickly. ATI's RenderMonkey running the Fur pixel shader. Here is a screenshot of the setup. I simply leave it like this and note down the temperatures.

A typical test run:

Before: CPU 53°C, GPU 60°C.
After 1 min: CPU 75°C, GPU 104°C.
After 2 min: CPU 77°C, GPU 112°C
After 3 min: CPU 78°C, GPU 115°C
After 4 min: CPU 53°C, GPU 116°C
After 5 min: CPU 51°C, GPU 117°C
At 5 min 6 seconds, it died.

I tried to put it on a glass table, and it ran for a little longer: 5 minutes 50 seconds.

As everyone here probably knew, this is the culprit:

Lenovo replaced the fan (obviously a "short fan") a month ago, and the system board again now (for the third time).

Here's the Crimsonland test setup, if you are interested. I just leave it running on the menu selection screen.

I have the same problem with my r50p - model 22G

After a few minutes (5!) of playing some old 3d game (mdk2) it shuts down with gpu reaching up to 117 celsius.

I managed to play the game using a lower resolution of 800x600 ang playing in window mode, not fullscreen.

what's troubling me is that the game is from 2000 and is achieving a very good fps (around 200 sometimes). If I could make it to stay around 25 fps I don;t think it wil generate so much heat, but I dont't know how to do it.
This shutdown problem happened with newer games such as halfliefe2, farcry, but only after a longer period of time (an hour or more).

If anybody knows about some workarounds, like gpu underclocking, somw bigger HW fan etc, please let me now. I can only think of playing outdoor on a cold winter day, and this is not very usefull...


Regards!

I managed to find atitool - a tool that helps underclock the gpu, and in this way I am able to play my game and the gpu stays aroung 105 celsius.
I do not get the same fps and the gpu is not doing all the work that it was supposed to do, but is better than nothing and for this particular case I didn't need that much performance.
Guys, I hope this might help you too.

Yay!

Lenovo is sending me a brand new replacement laptop. A T60p 8741-J9M:

T7600(2.33GHz), 1GB RAM, 100GB 7200rpm HD, 15.4in 1680x1050 LCD, 256MB ATI FireGL V5250, CDRW/DVDRW, Intel 802.11abg wireless, Bluetooth/Modem, 1Gb Ethernet, UltraNav, Secure chip, Fingerprint reader, 9c Li-Ion batt, WinVista Business

Quite an upgrade. The only ways this computer is worse than my current is that I had 1.5GB memory and a 1600x1200 resolution screen. So I think I can say this makes up for the downtime and the frustration in dealing with the support so far.

I'm definitely getting the 3 year warranty though, given my experience with the r50p.

I'm having problems with overheating gpu in my R50p model 1832 2ag and it's a shame my warranty ran out a couple of months ago.. I'm surprised Lenovo sent you a brand new replacement, congratulations!

The firegl v5250 in your new laptop is quite a bit faster, I wonder how they keep it cool in a much thinner laptop.

where did you find TPfancontrol 0.19??
