@BitMaxz : Thank you so much for the info!

Unfortunately, I threw out the broken fan and the one that was left. Didn't want to use them anymore.

To eliminate the no-hashing issue: would a fan simulator work? I have fans powered through a separate fan controller.

If so, do you know if  I use a fan simulator from the other brands or does the simulator need to be specifically for the Cheetah F1?
I found a Whatsminer M32 fan simulator kit locally, thought I'd give that a go, looks like this: https://i.imgur.com/eAwcMbY.jpg

I have a picture I took, comparing the broken fan to a standard 4pin PWM but you can't clearly see the wiring. From what I remember, seemed to be the same color-code as a normal fan.
