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 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
