Ok, so i built my rig a while ago over the summer and i kinda did it messy with cables all over the place and fans going in every which direction. I had a thermatake something hs with some 80mm fan on it and artic silver. Im running a pentium d 3.00ghz presHOT processor. My idel temp was like 60! So i reapplied the artic silver, and rearanged my fans so i had my intake on the bottom front and my exhaust on the top back. i put another 2 (intake and exhaust) on the side. The intake on side is lined up perfectly with my hsf. that brought me down to about 50. Then i had another impulse and rearannged my wires to give the best airflow and got all of them out of the way and pretty much like hid them in the nooks and cranys of my case. My idel is now 38 and im much happier
