I am setting up an Asus P5K Premium Black Pearl with a Q6600 and the Thermalright Extreme 120 CPU cooler. The P5K Premium special edition of this board comes with two fans for the board pipe coolers. Is it OK if I leave these off so I can keep the system quiet? I am planning to overclock to 3Ghz or a stable setting somewhere in that range; no overclocking on the other components, just looking for something stable and slightly better than stock since this going to be a workstation, not for gaming. The case will be an Antec Sonata III or NZXT Hush; each have just two 120mm fans.
