It is possible to increase left fan speed on a
DELL Precision 490n system up to 3.
value fan rpm
1 35460
2 64740
3 78510
Guess the speed factor 30 doesn't apply here.
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.
I don't think there are any fans running at 78k rpm. The real speed
is 78,510 / 30 or 2,617 rpm. You should set the fan_mult module
parameter to 1 for your system.
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.
Did you try to set higher values ?
