Preventing GPU fail on T30

[geka3250]

Hello!
I heard about high failure rate of ATI Radeon Mobility 7500 chip. I did some mods on my T30 and want to share it
Got northbridge aluminium heatsink from dead Gigabyte s462 motherboard, sawed right side a some to make trackpoint PCB fit. Applied AC MX-4 thermal compound on ATI7500 chip, 4 drops of glue diagonally. And thermal pad 1.5-2mm to make heat dissipation on keyboard.

30mins of 3D load with removed keyboard gives 68C on heatsink, I hope with keyboard installed temperature can go lower.
T30 have no GPU sensor, so I can't say about improvements, but without heatsing GPU burns fingers after 10 sec of 3D load and very hot to touch at idle.

I don't know how often GPU fails on the T30, but I know that the A31/p, and early T40/T41 tend to have issues with the GPU desoldering from the motherboard... needless to say, my SXGA+ T30 has not had any GPU issues under XP, 7 or Linux although mine seems to have a replaced motherboard from before I acquired it (also has both RAM slots working)
