You would think someone who works for Bitdeer repairing miners all day would remember that the 1397s tops are connected to ground. Silly me. Ill have to think of something other than thermal pads because the goal is to be super quiet. (APW3 doesnt qualify as super quiet i know, the 3.3 rail Isnt a bad idea. Ive 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
ive never built the bitaxe before so whats the power draw on there to get say around 700gh? I know on the s17+ you can get it to around 370gh per chip. yes bitdeer is the offshoot of bitmain. we dont do any manufacturing only cloud hosting, this is just a personal project. the heatsink issue is confounding me and I really am just tempted to use thermal pads but I know how hot these things run and just dont think that will cut it unless youre at like 100mhz, thermal paste would work but you run the risk of not putting enough on and it making contact same with thermal adhesive. The way the 17+ is laid out it has seperate heatsinks per asic but thats also in a machine with a 6000 rpm fan which im looking for this to sit on the corner in the floor and you basically forget about it, maybe get lucky with a block, or just hope pricing goes back up and by then even the little bit youve mined would be worth something. its really frustrating that you either can only do a hobby project with just a few chips or you have to go for it and basically just clone a hashboard. cause I can now see that my design wouldnt really work anyway because if its drawing that much power per two chips in series then me having 6 sets would make it impossible to feed, which refers back to at that point you basically just have to clone a board just with less chips.
