The Innosilicon A4 Dominator, like most miner is a noisy beast and runs around 80db’s and pulls approx. 540watt at the wall depending on PSU.
This unit has the Delta Electronics Fan rated at 2.4 Amps.
Sound level is in the 80db range
Temps with the standard fan run about 50-55c in a room at 23c. If placed in a warmer room the units temp will also rise.
I have also seen the following fans in the A4s.
