I have a early 04 powerbook g4 17 inch that i replaced the thermal paste on a while back. Now after reading through some posts im worried that the graphics chip and northbridge require a thermal pad instead of paste like the 12 inch but i cannot find any good information on the 17 inch. I cannot find a program that will monitor the mobility radeon 9700 temperatures either. Can anyone tell me if i need to take it apart again to put thermal pads in place of the paste on the gpu and northbridge or if im fine.
