Re: Open Source Bitcoin ASIC miner project that uses 2x BM1387 (Antminer S9)
I had a bit of time on my hands today so I made this..
Suggestions are welcome! I do think it looks quite good in Bitcoin-orange. 
FYI: I used the exported bitaxeMax.wrl from KiCAD and a random chipset heatsink STL, then assigned materials.
This looks very awesome! What I was thinking is, that I would love also a version that does not need active cooling, since this would lower the noise and power draw. When I have the time I will maybe try to design something with liquid cooling or one big passive cooler that can maybe used to cool many of these miners at once. Other people can obviously also design something with this idea also.
But passive cooling reducing power draw can actually be wrong. A fan uses almost no energy at all, meanwhile passively cooled, the chip would run hotter, causing it to draw more power. These chips like being as cool as possible.
You can even get into thermal runaway because of this: too hot > more power draw > gets hotter > even more power draw > even hotter...
