Ok, I'll switch that back then. It seemed more sensible to read the
actual fan values rather than the programmed ones (in fact I wonder if I
can just skip the read alltogether then and use a cached value but that
means I won't be able to detect failed fans...), but if you say it
behaves better, let's keep it the way it was.

I don't actually care too much about this, since the most annoyance came
from the slots fan.

As for the tickle, I'm not sure yet how to proceed. I'll look into it,
try various things. We can maybe just remove the tickle but that means
that a completely idle machine might start ramping up as the FCU times
out.

The old driver gets away with it probably because it always writes to
the fcu even if the speed didn't change.
