Here is a common problem: after you delete this app from sight, its icon may still stay on the menu bar and your fan speed is still under the control of this app. So what is the proper way to fully uninstall smcFanControl for Mac and restore the default fan rpm? We will provide multiple solutions to assist you in resolving these issues.
smcFanControl is perhaps the most well-known fan control app because it's been around for several years. It allows you to monitor the temperature of the CPU, GPU, and boot disk in the Mac's menu bar, and you can set temperatures for each fan on your Mac individually. There are three presets available, one for when your Mac is running on battery power, one for when it's running on mains power, and one for when it's charging. That way, you can ensure the fans don't drain the battery but also keep your Mac as cool as possible when it's plugged in.
The good news is that TG Pro supports macOS Monterey and Apple Silicon and is notarized by Apple. It gives you full sight of temperature sensors for CPU, GPU, logic board, battery, and boot disk. And you can control fans manually or set custom rules to determine when the fans kick in. Worried about your Mac overheating? Have the fans start at a lower temperature. Need to keep your Mac quiet? Set the temperature a little higher.
To install smcFanControl, drag its icon to your Applications folder after unzipping the download. To uninstall, drag the icon into the Trash (smcFanControl installs no permanent background processes or daemons). As mentioned earlier, the app stops controlling the fans when your Mac shuts down, restarts or enters standby mode, in which case minimum fan speed falls back to the system values.
I'm currently the process of fixing a friends Mac, they have smcFanControl installed, how do I go about resetting the mac back to it's default settings and get rid of what ever control smcFanControl had over the machine?
Macs Fan Control is a free utility that gives you all the Mac fan control settings you need. While not specifically a fan speed monitor, Macs Fan Control lets you see the RPM level your exhaust is currently working at and change it accordingly by moving a single slider.
I first tried FanControl from Lobotomo Software. BEWARE: it's a pain to uninstall (unsinstall instrutions on their page). Because it's designed for the macbook pro (yes, the laptop), it only controls 2 of the 5 fans and the minimum speed it allows is 1000 rpms. Up from 600 rpm, that is too much! I wish I could run every fan at 850 rpm!
From what I undrestand the fans are controlled by a chip called "SMC" as in "System Management Controller" and apple doesn't give you much control over it, apart from a clunky procedure to reset it! Note: resetting the SMC allowed me to get back to original rpms for all fans after FanControl had messed them up. Resetting teh SMC also seems to have reduced the tempearture of the air mesured at the exhaust -- at equivalent fan speeds and system load (that is: idle!). Strange... 2b1af7f3a8
