Hi all. Running a farm of 100+ S9s. Heat rejection for them is easy: Stick the rear fan through your cold/hot aisle wall and the issue is solved (cold air in from the cold aisle, hot air out to the hot aisle). Only downside is the power supply waste heat (7% of what is used, more or less) ends up in the cold aisle.
I have (11) Avalons coming on Monday and I've been trying to figure out an equally elegant cooling solution for them. Alas their power connections are on the back of the machine, so if I played a similar game as I do with the S9s, I'd either need holes in the cold/hot aisle wall for power cables, or would need to put the power supplies in the hot aisle - which just doesn't sound like a good idea (and would involve some other minor redesign issues like moving power from the cold aisle to the hot aisle to avoid having the power cords going through the wall).
FWIW - I'll be using Bitmain APW3++ power supplies for the Avalons, mostly because I have an excessive quantity of them. So many in fact that I've considered splitting them, with each power supply driving half of an 841. e.g. P - A - P - A - P... That would at least prevent power cables from crossing the back of the exhaust area of the Avalons.
Any thoughts or suggestions?
