We recently moved and I have a neighbor who is as crazy as I am. He plays around with computers like I do. Strangely enough he was in to H2O cooling about 2 years ago. He has tried just about every H2O manufacturer out there. I told him about my new rig and that I was going to H2O cool it with AC gear. He was quite familiar, to my surprise, about AC. So last night he said, "I'll bet you 20 bucks that I can better or at least match your temps on air." I said why not, bring it on. So he showed up this morning with his box of goodies and we fired up the new rig. We loaded windows on the new 150 gb raptor, very quickly I might add, and waited 15 minutes and recored the temps. Room temp was 22C and the CPU temps were 28 for CPU 1 using the XT and 29.5 for CPU 2 using the EVO. Then we ran PRIME for 45 minutes and had the following temps CPU 1 31, CPU 2 33.
We shut everything down and removed the H2O blocks, PITA, and cleaned the CPU's, applied AS5 and then we installed the two CPU air coolers. I must say I didnt like their appearance, but a bet is a bet. After installation we had some great mexican food and began round two. Same scenario, room temp was 22 and we did the same exercise, 15 minutes of windows followed by 45 minutes of PRIME. Idle temps were identical and the PRIME temps never went above 1C over H2O! I lost 20 bucks. The cooler was a Zalman CNPS 9500 and worked like a champ. It was noticeably louder, but it worked very well for much less $$$. It does make one think.
