HP Pavilion Nvidia Geforce Go 6150 GPU 110 degrees idle

I've read a number of threads on this issue and I may have created a problem. HP Pavilion dv9000 laptop was dropped by the user, hard drive now bad, replaced HD, manually reinstalled Vista with product key and...

Post install, all drivers, system behaving extremely sluggishly, 2 hours to install 4 Windows Updates and 10 minutes to shut down. Ripped it apart, reapplied thermal compound to the CPU noticed a thermal pad near the GPU heatsink was moved to the side, probably causing the issue. I took this pad off, applied thermal paste and...

Now the system is functioning normally; however the GPU is reported by various utilities (nvidia, everest, GPU-Z, speedfan) as ranging between 100 - 112 degrees while idle! (CPU temperatures normal)

I created an nvidia profile to downclock the GPU from 425MHz. to 100MHz. as soon as Windows loads, but that only gave me a couple degrees at berst. I also disabled Windows Aero and that only offered me a few degrees.

I realized these GPU's run hot but:

1) Is it terribly unhealthy that this GPU is idling at 110 degrees on average, and does it need to be corrected?

2) What can be used to substitute this thermal pad that was there previously?

3) Are there any other methods of lowering this temperature?

Thanks in advance!

 

There is no way that that is in ºC? that's for sure in celsius...

 

That's in Celsius.

 

You can use a copper shim instead of the pad.

Scroll down to the part where he used an aluminum piece to replace the pad. You can find copper or aluminum shims to improve the cooling of your gpu.

 

1) Yes, it's quite unhealthy. In fact, if you've been running it like that for any extended period of time (more than 10-15 minutes) you may have already damaged the board.

2) Either a metal shim as suggested above, or another thermal pad. Unless you use a particularly thick paste, the problem is that the thermal paste you applied isn't thick enough to reach from the heatsink to the component the thermal pad used to cover; which means that the component isn't being adequately cooled.

3) Building some sort of frankenstein contraption that supplies direct cooling to the component? Running the notebook only in temperatures of 5 degrees below 0? Nothing practical, probably.

 

Thanks gents, modified a larger square thermal pad to fit and reintegrating the laptop now, we'll see what happens!

 

75 degrees running various performance tests after 'fixing'. I think that's the best it's going to get... I'm not in the mood to take it apart and rebuild. What a crappy design.
