I have a btf90 http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2882721&CatId=493 I think I wasted my money with that fan, but its my fault, now my question is how does the liquid cooling improve the performance, my friends tell me that it is only for space save, and it will perform as a normal fan. Is it true? do you recomend me to buy a liquid for my core2 quad 6600 or another fan for 40dollars??
