For the noise issue plunge miner in dielectric fluid but for the next part I wonder how to make an air exchange to get hot air, at least enough hot air to warm a room.

You need to have an update firmware to handle the fan issue.

This Canaan Mining Warmer  is great idea, I wonder how it works, do you have more inputs HagssFIN  ?

Anyway Steamtyme this is a good idea, well done.
