How to configure fan control UGREEN NAS?

Hi, I would like to try unraid in my 2 bay UGREEN model but as soon as I start unraid fans go crazy loud whereas in UGREEN is is completely silent unless temps are higher than 55-60. Bear in mind this processor N100 is passively cooled, fan only cools drive and the interior.

I would like to ask what config should I enter in fan control to make it as silent as in ugos OS? Thanks
