Depends on your cold side temp. I was thinking the opposite direction. That we could reuse a lot of readily available apparatus to make cooling out of miner heat if the temp for the ammonia conversion was lower. When I saw it didn't work I figured I'd post anyway to save anyone else with the same thought the hassle of looking up that temperature.

Hydro Miner can do this

150C? I thought the asic chips cook well under 100C chip temp? Also 150C would require special fluids or very high pressures to avoid boiling.
