Anyone ever solve this? I have the same problem. Reset the SMC and no luck. Iʻm running the free version 1.5.9 on an iMac20,1. My iMac 27" usually sounds like a runway the fan is so loud with no apparent reason. No processes running. Thanks.

OS: MacOS Catalina 10.15.6 Hardware: Macbook Pro 2015 Retina

So my mac's fans for some reason just starting going full blast 100% of the time. I was happy to find this project, but cannot get it to work. I try setting constant speed, but the "current" speed of the fan never adjusts or changes. Am I missing some permission or other etc that I need to make this work properly?

I have already ran a SMC reset, and confirmed that SMC did reset, however, this has not fixed the issue.

Same happened on MacBookAir7,2

Hi! I have the exact same problem. Constant RPMs around 7300, 13" model, temperature goes from 35º to maybe 55º (not really overheating). Heres my technical info. Any help would be appreciated

Another report from iMac Pro image

Another report from iMac Pro ! []

Seems iMac Pros are known for overheating (what's new), given that they are Mac Pros (sort of) in an iMac's body. In my case, the difference between "Full Blast" and the apparent OEM max fan speed is that the former isn't enough to prevent overheating and shutdown -- so basically (my) iMac Pro when working hard suffers heat stroke on MFC. (I haven't checked to see if "Automatic" also can't reach OEM speeds -- Auto just a passthru?
