1, All water cooling miner machine can be use like : M33S++/M53 / S19 Hydro / S19XP Hydro/S19PRO+ Hydro and etc.

2, Most air cooling (like s19 & s19j/pro series/L7/D7/m20/m30s/m50 series and etc.
can also use this water-cooling Row, just need to use a water-cooling plate together.

3, If you want to do overclock, then just need to add air-cooling overclock power supply +water-cooling overclock board accordingly is ok.(water cooling model no need to add water-cooling overclock board, only need to add water-cooling overclock power supply is enough)
Pls let me know which model and how many pcs you need when you are inquiry.
