With my settings, at idle the cpu runs at 32°C and at full load about 39°C (according to sensors reading) at a room temperature of 23°C. I guess this is safe even considering a conservative margin for the temperature readings. Or do you allude to that the fancontrol script bundled with lm-sensors can be unreliable? Anders
