Ok check this out, buy 2 Silenx 14bB fans 80mm of course and then replace the one in the ice system with one and then cut off the mesh grill from the back of the case that covers the ice radiator and mount the other fan on the other side and have both of the sucking air out, I'm running barton 2500 @ 3200 and its 46c idle and 55c load in prime 95 :D and its damn quiet too alot better then when my speedfan used to kick in on the sunon, I have them both running off the mboard and turned off speed fan and just set them both to full. Another thing I did was replace the psu fan with a adda fan from
