It doesnt seem that the miner monitors fan speed in this miner version. As far I can tell it runs the fans on full and completely skips the fan test cycle that usually occurs post boot with other Bitmain models.

It also runs incredible cool at just under 35 chip temps with sub 30 board temps. Thats with no cooling in a warm weather climate.

Obviously its because of the low wattage requirements. So are these fans total overkill for this miner?

Appears they slapped in stock S9 fans with no rpm governance or checks.

Can anyone confirm this?
