This is fantastic. Love the set up. I had some USB antminers running off solar for a year, now just moved my recently bought S7-LN, which hashes at 2.7Th from my study to the loft. The noise was simply too much, along with a 600w air cooler. So now it runs out of hearing range.
This has made me think in the winter months, I could duct the output air into the house from the loft. You obviously worked out pressures of what they can do here, do you think I could leave the intake as is and run duct directly down into the house? if so, what kind of length would be a max before I start hitting problems.
I would think 6ft of ducting is acheivable, just wondered yours or any others thoughts on this.
