I am completly baffeled, no matter what i so i cant make my AMD Atholon XP 2400+ to run below 63*C. I havent had any problem for two years but suddenly it has started overheating all the time. When i first saw it was running around 69*C (my Mobo shuts it off at 70) i lowered the External Freq. from 133MHz to 100 and that has given me back 5*. My CPU Fan is running 3792RPM Im using the standard CPU Fan and heatsink (AMD Pack-in) on a Asus A7N8X Deluxe (Rv. 2) (which reports a MB temp od 28-30*C) along with a E-VGA nForce GeForce FX 5200 Ultra chipset AGP card (which has its own GPU fan). There are four case fans, 2 intake (red LEDS) and two output that came with the case( Chieftec sever chasis wit 450w power supply). I really have no idea what the problem is. could it be that the thermal compound has decayed or something? (like i said it ran for two years with no problems). Also right now the side panel of the case is open in an attempt to allow better airflow.
