I noticed something lately. Whenever I check my MBP's temperature readings from iStat Menu, the GPU diode is always 10C higher than the GPU heatsink. Do you think this is caused by bad thermal paste application or is it normal? Also, my MBP is still in warranty (July 07) so I don't want to take it apart and reapply the thermal paste. Do you think if I take it to the apple store and show them the issue they'll reapply the thermal paste or do I just have to wait until I'm out of the warranty.
