Thinkpad T61 w/ NVS140 Running oddly hot?

Hello, and happy holidays! Looks like my first post if going to be a long one. :-D

I've got a Thinkpad T61 w/ an C2D T7700 and a Nvidia Qaudro NVS 140. Its been in used for about 3.5 years now and I really love it. However, as time has gone on its gotten hotter, and hotter, and hotter. So I've cleaned it many times - no big deal - and every time its improved. This time around however it was idling at at around 60 CPU and about 65 GPU no matter what I did. So i took it apart, reapplyed thermal grease, oiled the fan, and of course cleaned it. Helped the CPU immensely (now idles at around 40 like when I got it) but the GPU is still idling at around 60-65. It hits 80 under load. Is this normal? I took it apart again and reapplyed a smaller amount of the thermal grease (Artic Silver 5 might I add.) to it and its still doing the same thing. Bought a new heatsink/fan assem - same thing.

Also, when I had it apart I noticed the GPU was on a Nvidia G86 chipset - seemingly the same one the infamous 8400GS/8600GTs were on that there is a huge class action lawsuit about right now. Could the GPU be failing? I know the Quadros are rebranded/stable drivered Geforces - but I kinda hoped the Quadros would be exempt from that whole mess. Maybe not?

At anyrate - help would be much appreciated. :-D

 

Its normal from what I've read.

Whats the GPU temp under load?

80 C for CPU under load sounds acceptable to me.

 

Nah, the CPU isn't going over 70C load - the GPU is what is hitting 80-82C. Thats what worries me.

 

I just cleaned out the laptop and put some AS5 on the chips, but I still get around 60 degrees idle for both my CPU and GPU.

 

your heatpipe on the fan maybe faulty (i.e. leaked working fluid from heatpipe).

 

Qaudro NVS 140 in my R61i is idling at 45~50.

 

That still sounds fine too. What did it used to be?

 

If you don't care about fan noise you can always tweak fan rules (as I did).

 

Seems like its pretty steady at 55-60c with the GPU and the CPU is plenty cool. Guess I should stop worrying about huh? It seemed like it was cooler when I first got it, but now that I think back I remember playing UT2004 on the thing at a lan party on decent settings for a couple hours and almost burning my hand when i touched the bottom. The new h/s assem seems to have helped atleast stabilize the temps also, and chipset temp is much lower - so I don't think anything is leaking from the pipe on the chipset/gpu side.

How would I change the fan rules? The thing isn't even loud when the fan is on full blast as far as I've heard.

Also - an R61 would be cooler - they're much bigger. Me and my want for a thin but powerful laptop...sigh.

For Linux? :-( Doesn't do me any good.

 

There is probably somewhere over net Windows method too, but I'm not familiar with it.

 

You can download TPFanControl and control the fan state.
