On my first AMD build, I fried the CPU... I used a themaltake something or other 7 with a huge orange 80mm fan on top of it.... CPU was an AMD 2200+ XP, didn't use thermal paste (stupid n00b) and needless to say the system didn't live long enough to POST.... the CPU CORE was FUZED to the bottom of the HSF.... not stuck, I mean it FUZED with it.... chizzled it off with a screwdriver, and a nice chunck stayed attached to the HSF.... SO, I got an AMD 2400+ XP and that is my current folding system, on STOCK cooling.. lol
I learned my lesson from the $250 fried CPU.
