rgt был бы я в

rgt был бы я в Москве, сходил бы в датацентр, а так - гадать остается...

fan1:     4411 RPM  (min = 42187 RPM, div = 2)
CPU Fan:     0 RPM  (min =  155 RPM, div = 128)
fan3:        0 RPM  (min = 21093 RPM, div = 2)
M/B Temp:    +32 C  (high =    +1 C, hyst =    +8 C)   sensor = thermistor
CPU Temp:  +66.5 C  (high =   +80 C, hyst =   +75 C)   sensor = thermistor
temp3:     -48.0 C  (high =   +80 C, hyst =   +75 C)   sensor = thermistor

Это после рестарта:
А вот - 15 минту спустя...
fan1:     4500 RPM  (min = 42187 RPM, div = 2)
CPU Fan:     0 RPM  (min =  155 RPM, div = 128)
fan3:        0 RPM  (min = 21093 RPM, div = 2)
M/B Temp:    +33 C  (high =    +1 C, hyst =    +8 C)   sensor = thermistor
CPU Temp:  +81.5 C  (high =   +80 C, hyst =   +75 C)   sensor = thermistor   ALARM
temp3:     -48.0 C  (high =   +80 C, hyst =   +75 C)   sensor = thermistor

Толи CPU FAN сдох, толи его не туда воткнули... А если не туда. то от чего питается System fan ? Одни загадеки...
В логах: CPU0: Running in modulated clock mode

If i recall correctly it's hardware set, i'm not sure if BIOSes can modify
that these days. One thing you may want to note is that in the modulated
state the processor doesn't process interrupts and runs at a 50% clock
duty cycle. So there is a large performance loss when its running in this
mode. You really should consider looking into your cooling...

Yep, it's normally 50% modulation for 1ms or until the temperature drops
below threshold, whichever comes first with interrupts remaining pending.
