I would appreciate opinions here on which cooler to get for a 6600GT video card with quietness being important. I like the idea behind Arctic Cooler's exhausting heat out of the case, but I don't know how it holds up with regard to noise. The Zalman VF-700 should be able to cool my card using 5 volts, at least that's what I believe, but I don't know how that unit compares noisewise with the AC Silencer 6, which has a maximum rating of 1500 rpm. The other question I have is how significant is cleaning these coolers? I would appreciate your advice on this whole issue and guide me to making a proper decision. Thanks!
