Under full CPU load for a longer time, it can get up to 85-90 degrees Celsius when I use the lowest setting in the motherboard. With maximum cooling it gets to 72 degrees in such a case. When I use fancontrol I can make it such that it is around 59 degrees while idle and at most 75 degrees when fully loaded. A temperature of 59 degrees is the temperature just after it starts up so the minimum temperature. Right now I am just using a setting which is one higher than the lowest in the motherboard and that is acceptable, but it will be a bit louder under idle conditions. Under full load it will get approximately 80 degrees. > > > Phil P. > -- Nonsense and other useful things: http://brakkee.org MountainHoppers: http://mountainhoppers.nl Track Detective: http://trackdetective.com Twitter: http://twitter.com/ErikBrakkee _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
