Also the reason I did that is because I have antminers running in the same room so I did not want them sucking in hot air.
Trying to think outside of the box.
Were you high when you came up with that idea?
The tighter the space, the less air to put your heat in. And it doesn't really matter if your ASIC draw air bit hotter than ambient, what's really important is venting the hot air outside!
Venting 101: Dump the heat to the outside, with exhaust, let the fresh outside air in through passive intake.
I was able to cool a dozen rigs and some ASICs through 2 small windows that way, when i lived in an appartment~
