Hey. I'm using the Athlon XP 2200+ Thoroughbred with the retail stock heatsink/fan. I get about 44°C at normal, and about 50°C at full load. I usually get the "burning" smell from my case, but I'm thinking its because of my lack of fans for the case, only one on the side and 2 on the power supply. My mobo(Asus A7N8X DX) temp is usually about 4-5° cooler than the CPU. Any suggestions would be appreciated.
