You would think someone who works for Bitdeer repairing miners all day would remember that the 1397s tops are connected to ground. Silly me. I’ll have to think of something other than thermal pads because the goal is to be super quiet. (APW3 doesn’t qualify as super quiet i know, the 3.3 rail Isn’t a bad idea. I’ve used kicad before just more familiar with easyeda. What should the current be for two chips? The one i have is a 3.3v 1amp

Hey, Bitdeer is a Bitmain offshoot, right??

The APW3 sounds a lot better if you put a Noctua fan in there.

Current for two chips in series is the same as one. Rumor has it a single BM1397 can hit 25W if you really go for it. So, that's like 15A for two chips at 3.3V
