For reassurance prior to over-clocking my AMD DURON 600 with ABITKT7-RAID, I am performing a 48hr burning period and have noticed the temp of the CPU hovering at 60-C and this is only at idle! The case has a front and rear fan, the front is diverting air away from the case and the rear has a duct, which draws the air from the heat sink/fan area. What should I do to bring the temp down?
