inspired by the discussion of macbook and macbook pro temperatures being crazy because of the thermal grease, i decided to do the same thing to my ibook g4. the processer, "some other block also being cooled", and ati graphics card were stuck to a heatsink by 3 thermal putty. i took them off, and applied artic cremeque on it. there is a small gap between the heatsink and heaters, so i applied extra paste to connect the two. i reassembled the computer back. here are the results: power adaptor set to fastest One safari window open. no other tabs. graphics processer 57 cpu 50.7 battery 37 C memory 52 C warcraft III the frozen throne 74.8 graphics card 65 C cpu 37 battery 57.5 memory is my ibook cooling better or worse? i forgot to check the temperatures before the change. should i revert back to the thermal pads? the temperatures seem kinda hot, i think i made it worse.
