You'll probably have to replace it or find a way to repair it. Looks like a physical issue on the fan itself.

Either the fan itself is seizing up or its already dead and being spun by the front fan. Replace the fan and you should be good to go. Make sure your replacement fan can spin at least 4500 rpm, the firmware doesnt like anything under that.
Stop buying industrial miners, running them at home, and then complaining about the noise.

so its a normal behaviour for a diying fan ?
it goes from 1680 to 3700 rpm.. it was working at like 4500 without droping..
EDIT: after cleaning it it works now.. but now the other one is slower.. wtf

You sould periodically clean your miners as dust builds up and coats the heatsinks and fns as youve found out. Switch it off and clean everything and see how you get on.

Have you plugged them in the right way around? Im guessing when you cleaned them you have plugged the fans back in different connectors on the controlboard
