Taperlark / CoolCurve
Guides to temperature monitoring, custom fan curves and fan control on Apple silicon. Start with manual controls, learn how curves and presets work, and check the limits that apply to your Mac.
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.
/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.
Macs Fan Control, TG Pro, and CoolCurve compared row by row from each vendor's own published pages: pricing model, supported chips, control versus monitoring, what happens on quit, and the limits each vendor admits to, with every claim linked.
The real alternatives to TG Pro and Macs Fan Control on a modern Mac: Stats and smcFanControl for free, iStat Menus 7 as a monitor with fan curves, and CoolCurve for control first on Apple silicon. Every claim checked against each vendor's own page or repository.
Set fan speeds from the menu bar or use custom curves to increase cooling as a sensor warms. How to start with CoolCurve, switch presets and return to Automatic.
Nine things to check when a MacBook fan runs loud for no visible reason, in the order that actually finds the cause, before anyone tries to sell you an app for it.
Two temperature apps on the same Mac rarely agree, because they read different sensor paths and summarize unlabeled diodes differently. Here is CoolCurve's own pipeline, including what it refuses to guess.
Eight fan and sensor apps for Apple silicon Macs, sorted by what each vendor documents: which set a fan speed, which only read one, and what CoolCurve's own source documents as its own limits.
