I'm building a pc for my friend, the last pc that I constructed a pc by piecing together motherboard and the rest was over 6 yrs ago when pc's werent so intimidating. I figured it can't be too hard to do like I've done in the past by simply following directions like I did before, besides it's basiclly easy right?... Well I've gotten all of the parts together, put the heat sink on the CPU Intel Pentium 4 like its boxed directions declared to do, it had a small square of heat sink material on the bottom of the heat sink and it told me not to damage or replace it because it came from Intel and was special material for the heat sink to help draw heat to the heat sink. Well it didnt say anything about applying any heat sink paste or to added it, just putting on the heat sink to the CPU and locking it down. The Motherboard instructions say to put heat sink paste on it so I'm really confused at present what to do. Any suggestions please? Otherwise Ive got everything else ready to plug in and turn on the pc then set the Bios then the 120 Gig hard drive.
