Summary0002181: FAN control behaves like it has no hysteresis ?
DescriptionFan speed jumps when CPU or GPU temperature is on a fan high speed limit/boundary.
Looks like hysteresis value doesn't work


You can see that Fan goes up (in fact its enough to set it above 0000017:0000065% to go full speed) and goes down (below 65%) and it changes many time during CPU cooling (and heating)
