You usually get what you pay for though..Ive heard nothing but good things about the zalman. I probably wont go up to 3.8ghz, but ive heard people using the zalman for 4 ghz and 35-40C idle and 45+ on load. thats not bad at all, and if those stats are consistent, then id buy the zalman. I dont mind the extra $30 or so for something nice. And ive heard that AS5 is better than mx2 because of the silver particles and other stuff. If price didnt matter, the zalman would be the best right?
