Today in the morning something strange happened. When I turned on my
Blackbird then (as usual) i ran all the fan on high speed. That was
normal. But when the Fedora booted then fans continued to ran on highs
speed. It was a bit noisy but the CPU temperatures were 54 degrees
(Celsius) at max.
When I turned the system off and started it after few hours then it
behave "normally" - the fans were much quieter and CPU temperatures
were about 62~65 degrees (it I didn't noticed it here: I add a third
fan to the system and it seems to be able to cool CPU to 60+ degrees
instead of 70+).
Today was unusually cold day (24 degrees). In all previous days there
were outside temperatures in 29~34 range. But this does not explain why
the system decided to put all fans on full speed.
Well, my O2 behaviour is sometimes similar - during hot days it
sometimes runs its fan on (relatively) low speed and in cold days it
sometimes decides that full speed is the only option... And the
Blackbird now sits on the place that the poor old O2 used to occupy...
I have no natural explanation for this. Maybe some ghosts are inside?
