erm, this is what i did, just a huge chunk of heatsink to put onto my HDD, havent applied any thermal paste yet.

the bottom part is hotter because the motor is located on the bottom of the frame, so if heat dissipation on top is faster, it can absorb the heat from bottom up.
ps : look out at my siggy as i will sell them soon!!! cheap and practical solution

yo.. i wanted to know, my cpu tem will grow until 60.0'c..  well.. juz plan for modifying the casing lo.... Plz asend some pic, so that it would give me some idea... cHiow...
