I have a pretty chronic problem with my CPU temperature - an AMD Athlon XP 3000+ on an ASUS A7V600 mobo. The idle temperature as reported by the mobo is about 70C right now, and I've seen it go as high as 91.5 (switched it off immediately when this happened). I've tried 2 fans, a generic cheapo fan and a Coolermaster Aero7 lite, neither of which has reduced the temperature to normal levels. I've got two case fans in the usual places, cables nicely hidden or tied down, and a dual fan PSU in there to try and reduce the heat but again, no difference.
Any suggestions to get it down?
