It seems like it.

The fan is totally covered by a casing and it is positioned far away from the case of the miner.

Like there is a little gap between the miner and the fan.

I decided to take it off for more exploring and will post pictures once done.


The A721 is quieter than the S7.

The current A721 with air forming cooler is a little bit quieter than the older fan due to the lower fan speed.

I do not know if it suitable as a home miner or not but I have a dedicated place for the miners.

All I know that the R4 is the only home miner but with lots of issues.
