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...
I suggest to disconnect front fan (that what I have done) till they release firmware update. It will drop noise level 50% plus I put under the unit noise cancellation pad. It helped another 10%. Hopefully it helps.
I swapped out both fans for SILVERSTONE FHP Series SST-FHP141-VF, temps don't go above 50 and power at the wall dropped to 280w.
My next test will be to use 2x Phanteks PH-F120MP 120mm PWM High Static Pressure Radiator Fan and or 1x Phanteks + 1x SILVERSTONE. If needed I will put a honeycomb cell on the rear fan.
How were the results with the 2x Phanteks on the B3 miner? Did the miner stay cool enough and how was the noise?
