I just reinstalled my operating system (Crunchbang on Debian testing), and all of a sudden the fan is running as fast as it can even with 0% CPU. The air coming out of it is cold. The only CPU frequency governors available according to /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors are performance and powersave, and it was already set to powersave by default. What else could be wrong?ruukasu@cb-lt:~$ sensorsacpitz-virtual-0Adapter: Virtual devicetemp1:        +38.0C  (crit = +108.0C)pkg-temp-0-virtual-0Adapter: Virtual devicetemp1:        +39.0C  coretemp-isa-0000Adapter: ISA adapterPhysical id 0:  +39.0C  (high = +87.0C, crit = +105.0C)Core 0:         +32.0C  (high = +87.0C, crit = +105.0C)Core 1:         +39.0C  (high = +87.0C, crit = +105.0C)
