Cooling for Laptop GPU

pomijanlewa · 06-10-2008, 09:10 PM

I was using HP Dv9000. It has got a Nvidia 7600 go 256 mb.
History:
The graphics card one day got faulty and started giving horizontal lines at the bios level and windows was not booting and giving blue error

screen. However I was able to logon to windows in safe mode.
I'm positive that it got faulty because of overheating.
Now, I am replacing the motherboard and as I opened the laptops, I found that there was no cooling gel sticking to the GPU chip or the heat sink of the chip.
I want to know that If i put some gel at the new motherboards chip, will it be okay. I mean that can all chips support cooling gel. Are these gels conductors or non conductors of Electricity?

Please I need a quick response as my laptop is still open.

Your Lappy will be just fine. Most thermal compounds are not conductive..

-Just make sure that if the card looks like this, only apply the thermal compound to areas outlined in RED. If the heatsink does not cover the GDDR memory chips on the board, do not cover them and worry only about the GPU chip.

Any thermal compound/grease/paste/gel will work and if you apply correctly you don't need to worry about conduction.

That's correct. Also, you only need a BB-sized glob of thermal compound for the GPU, and maybe twice that for the RAM (if the heatsync covers the RAM; otherwise leave it off).
