2.4C northwood @ 3.2 (267 FSB). Ram 5:4 running at 213, when running 1:1 ram was fine up until 220. Getting 50c idle & 60c on load, at default 2.4 ghz I get 40c idle & 54c load. Thinking about putting a 6800gt in here (right now i have 9800pro). Hopefully, the cpu won't be too much of a bottleneck for 6800gt. In my other rig I have athlon64 3200 @ 2.6 ghz, and an X800XL. The AMD64 idles at 34c & load temp is only 45c, much cooler than the P4.
