Guyz - I tried to change speed of the fans...
This shit is screeaming like a pig in my basement and there is no need to be like that - chips have just around 45°C.

U used bitmain-fan-ctrl and pwm in SSH, but this shit doesnt made a change. It doesnt have any fan-ctrl or what?

Could somebody help?
How much temperature could this chips have?
Thinking about giving there some computer fans...
