Monitor (-m) flag modifies fan speed on exit about nvfancontrol HOT 5 CLOSED

Hello! This seems common to windows and linux so I removed windows from title. I suspect this happens because nvfancontrol will put the fan back to automatic control when exiting. Since your fans are managed by an external tool (which uses manual control too) setting it back to automatic will revert to the default behaviour of the GPU's firmware, which is probably to turn off the fan under some load/temperature combination. Can you confirm that by loading the GPU enough to trigger the fan without using X1 and then using monitor mode? It should not affect the automatic operation at all.

I believe a better solution would be not to touch anything related to the fans if running in monitor mode. Should be relatively straightforward.

I did exactly as you've asked -- your theory is correct.

I concur that this would be the correct solution. I suspect the code for this should be quite easy. Thank you!

I think I fixed it. Give it a try!

I can confirm this fixes the problem. Thank you so much!

The fix is now in master, will be in the new release whenever that happens.
