Hmm, the antec tricools don't bother me at all when they are on low. With a overclocked x2 3800+ @ 2.6ghz in there, with an arctic freezer 7 pro, and a 8800gts 320mb, things stay plenty cool. I've put both HD's in the lower drive bay, so they don't add to the heat in the mobo compartment either. In reviews the antec tricools performed pretty good, not the best, no, but at low they are almost as good as the best fans, in terms of noise per amount of air that gets pushed. Since you're not overclocking and such, you should be good to go with all 3 of them on low. Btw, you should look for a good p180b or p182 deal. The p180b's are identical to p182's, and often cost a fair bit less.
