I upgraded from FC12 to FC14 and now the system/case fan blows full speed constantly. I also moved from i386-PAE to am64.
The CPUs are cool, the machine is basically idle, and the fan noise is really annoying (and blowing cool air).
In FC12 the fan would auto-adjust with CPU load. This is not the case now.
I ran sensors-detect and it doesn't seem to find my fans:
[root@pangea modprobe.d]# sensors
Adapter: Virtual device
temp1: +40.0°C (crit = +75.0°C)
Adapter: PCI adapter
Core0 Temp: +38.0°C
Core1 Temp: +41.0°C
Adapter: SMBus nForce2 adapter at f400
temp1: +42.0°C (low = +0.0°C, high = +55.0°C)
temp2: +36.0°C (low = +0.0°C, high = +55.0°C)
I don't remember ever having to even run sensors-detect in FC12. I searched the board for a bit and didn't see any solutions. Any thoughts? I'll attach the full output from sensors-detect.
