You might also check the GPU Temperature if that's reaching high values. CPU Package is the most important value in this case for CPU. This includes all M1 versions, MacBook Pro (13, 15 and 16 inch), Mac Pro, iMac (21.5, 24 and 27 inch), iMac Pro, MacBook, MacBook Air and Mac mini. This determine the number of samples the value needs to out of range in order to spin the fan down, sort of hysteresis. TG Pro natively supports all Macs, both Intel and Apple Silicon, from 2008 all the way up to the latest 2021 models. It is fully compatible with macOS 12 Monterey, all the way back to 10.11 El Capitan. It also has a separate secure service for fan control, only HTTPS/SSL connections and built-in support for the Internet Access Policy (when using Little Snitch). TG Pro is notarized by Apple and uses the Hardened Runtime. Get local or email notifications for temperature events along with full logging for further analysis. If it's getting hot, manually boost the fan speeds, or allow TG Pro to do it automatically to help keep the Mac cool and running fast. While increasing your GPUs clock frequency and voltage, the fan speed. Quickly view CPU, GPU, logic board and hard drive temperatures, check battery health and the other hardware diagnostics. MSI Afterburner is the most used graphics card software for a good reason. So I decided to set up the fans manually, the Mac now runs much cooler and still it's not too loud. Extend the life of your Mac with TG Pro, whether it's an older iMac, a 16-inch MacBookPro or a brand new M1 (Apple Silicon) based Mac. Macs Fan Control indicated that the PSU was running on 70C and more, and something made a buzzing sound (like a wire dangling inside a fan, which was not the case).
