The output from `sensors` seems incorrent to me, temperature wise at least:

Case Fan:    0 RPM  (min = 1318 RPM, div = 128)
CPU Fan:  2721 RPM  (min = 1704 RPM, div = 8)
fan3:        0 RPM  (min =   79 RPM, div = 128)
fan4:        0 RPM  (min = 21093 RPM, div = 64)
Sys Temp:    +37°C  (high =   +45°C, hyst =   +40°C)
CPU Temp:  +52.5°C  (high = +45.0°C, hyst = +40.0°C)
temp3:    +123.0°C  (high = +80.0°C, hyst = +75.0°C)

Note: the machine has been working fine with FC5 till this week.
