I just recieved a duron 650, an abit KT7, and a cooler master heatsink+fan. I ordered all of this from the same outfit and had the intention of overclocking the 650. Well cpu, heatsink and fan all came assembled on the mobo. I need to take the heatsink and fan off to close the L7 bridges right. So my question is if they already put the heat compound stuff on the chip and mounted the heatsink on it will I damage the cpu by taking the heatsink off of it?
