Original GitHub issue: https://github.com/hirschmann/nbfc/issues/425

When using NBFC my fans seems to fluctuate with a delta of 2,6% meaning they will either go 1,3% above or below the set fan speed every second (several times per minute). This behaviour does not happen with the regular system fan profile. Any ideas what could cause this?

EDIT: Couldn't find the log files that are referenced here:

https://github.com/hirschmann/nbfc/wiki/Files-and-directories-overview

so I made my own using Process Monitor. Hopefully it's of some use.
