What is a very good cooler and very quiet for socket 754. Im using an Abit NF8 s754 nforce3 ultra 250gb blah blah. Ive looked at a few zalman ones, also the silent boost k8, and the thermalright xp-90 series. My ultimate goal is to idle on the low 30's so that my Antec sonata case will shutup and stop increasing fan speeds for no reason.
