CoolCurve notes
From the product journal.
Is Mac fan control safe? What a fan app can and cannot do to your machine
Fan control software can only request speeds the Mac's own management firmware accepts, and the firmware keeps its protective veto. Where the real risk sits, which direction is harmless, and how the careful vendors design for the difference, with Apple's documentation carrying the claims.
How to do /skipcheck for Macs Fan Control, and what it actually fixes
/skipcheck is a Windows only launch parameter for Macs Fan Control that skips its Apple hardware check under Boot Camp. Where the vendor documents it, the exact command to run, why it does nothing on macOS, and what to try when it does not help.
