Just an update to this topic: BEFORE: FBSD 8.2-RELEASE Phenom II 955 w/ stock cooler Idle temp at turn-on: 42~44 C Idle temp after 3 hrs: 48~49.5 C Load (95~100%)temp: 64~66.5 C (w/ peaks of 67.5) With the side of the computer case off. I replaced the thermal grease (as advised here) with a new one but that didn't change those figures. AFTER: FBSD 8.1-STABLE Phenom II 955 w/ a ZALMAN CNPS 10x PERFORMA cooler Idle temp at turn-on: 35~37 C Idle temp after the compilation: 43~44 C Load (95~100%)temp: 54~56.5 C (w/ peaks of 57 tops) With the side of the computer case ON. On both cases, the load was provided by compiling Vbox (4.0.2) under KDE and room temp was around 30 C. Powerd on for both. I noticed one thing. With 8.2-RELEASE, the compilation process stays at 100% load a lot longer than with 8.1-STABLE. During the compile with 8.2, there was a time I counted about 9 seconds at 100% load, plus about 3 or 4 extra 100% load of around 5 secs each. With 8.1, I only saw 4 half second ( well, it seemed like a half to me) 100% load peaks. And that was it. Beleive me, I counted them.
