right im about to resurect one of my pcs, just got a new fan (coolermaster silence) and heat sink for it but im wondering about the heat paste stuff your suppose to stick on the bottom before your place the new heatsink on. Can i get away with none or will my pc melt (its an athlon 1700). its got a small square of powdery stuff on the bottom of the heatsink but im guessing that is the main part for the center of the processor.

i dont mind going to get the paste for it but im just curious as wether i need it or not
