I know Athlon CPUs are less sensitive to heat than P3 Coppermines, and put out a lot more of that heat. This CPU temperature I'm getting from my unoverclocked 800mhz Socket-A Thunderbird makes me wonder... I have a rather small, standard S370 celeron fan on the top. CPU temp's around 42-47 degrees depending on what I do. System is stable, but is this too high? What kind of temp are you all getting from your Athlons and Tbirds?
