Those are actual rpms, not just a multiplied rpm. What I mean
is that you can hear the fan spinning up or down and the
temperature going up or down accordingly.

But even setting it to 3 is not enough to spin at maximum
speed. Anyway, now I can load the system without the FBDIMM
going above 75oC.

Sure, let me know your findings. In meanwhile, I am using the patch here.
