I have an epox 8kha+ motherboard and an oem Athlon XP1800+, is it normal for me to have a cpu temp > 45C? I've tried using programs like CPUIdle Pro to lower the temp when the CPU is idle, but now it's not working. I have a Thermalright SK6 Copper heatsink and a regular sized fan on it. Do you think I installed the heatsink incorrectly? Or maybe I didn't put enough thermal paste on the diode?
