@BitMaxz:
I got this: https://thanosmining.com/products/ebang-ebit-e10-e102-e103-fan-simulator-full-speed-version

Description reads:
"Also suitable for models such as Cheetah F1.
Avalon 921 and other special interfaces are common to all series.
It works fine as long as the connectors are the same."

Takes about 2 weeks for it to arrive.

Thank you once again for your insight, I will keep you updated. Trying to get into mining on a budged is hard af, especially when you have to deal with all of this bs that just doesn't exist with Bitmain machines (less hassle, higher up-time, parts availability, knowledge etc.). Had an Antminer S9 last year with Braains OS on it and I thought it was hard but manageable. Oh boy, was I wrong...


As for cooling: I have 4 parallelminer fans + fan controller + a PC. Gonna mount the fans in a push-pull config, power them via the PC for control and for powering the fan controller.
I'm expecting that if at least the temps are the same, the noise will be way less. Mining software will be happy because it will "detect" fans, hashboards will be happy since they will be cool, I will be happy with the noise and the control part.

The fans that came with the Cheetah F1 were these: YD YD12038B2G 4.5A(GP)
They are 8k+ rpm fans. They screech, they are impossible to service and the vibrations generated from the rpm unscrewed the screws that were keeping them in place which is why one of the fans failed, because after noticing this, I tightened the screws more and since the vibrations had nowhere to go, the ripped apart the fan from its casing and it killed itself.
Better yet: at their peak rpm they push out ALMOST as much CFM as a standard 6k rpm parallelminer fan pulling almost half the amps Smiley) These YD fans are literally broken, from design to finished product.
