The displayed temperatures changed to 67.5°C / 66.0°C. Still, this seems to be too high. The power supply's fan runs too slow for such CPU temperatures. In older kernels it becomes noisy above 50°C. Under load the temperatures shown are around 95°C, way too high. -jo -- -rw-r--r-- 1 jo users 62 2007-08-08 21:06 /home/jo/.signature
