Hi,

This is my first post on here so please don't be mad if I am posting in the wrong place.

I have my first antminer S9 set up in my garage but the heat coming out of it gets the room really hot. I see some videos on YouTube where people have some aluminum circular thing around the end of the antminer to get the air out of the room. What material is it/what is it called/ and where can I purchase something like that?

I also see some videos on youtube where they have a black 1600W power supply. What brand is that/Where can I buy it? I dont like the Bitmain power supply because the wires are not long enough and I want a more professional one.

thank you very much.
