Do I need thermal grease?

You should buy aftermarket thermal grease and apply it plentufully, as you will see better performance. Especially if its AMD. Intell is the way to go, AMd systems hate the heat and don't perform well. And when your playing crisis and stuff... Feel your system; computers are hot.

Look, according to Arctic Silver, it depends on the CPU, and it says to rotate the CPU 1 - 2 degree, (not 180), like i mentioned. But I guess they know less than you eh THE ENFORCER? http://www.arcticsilver.com/instructions.htm

BTW Hack, you summed it up perfectly!!

just one last thing how does one "talk mess"? THE ENFORCER?

Overclocking is more trial and error than skill anyway. More relevant to the equation would be luck of the silicon*how much dough you spend on the douche.

It's funny, this thread.
