The Bitfortun BS-2 is a water cooled Bitcoin miner made for home use. It runs two BM1373 chips, and the voltage regulators sit on the back of the board so the fan blows across them constantly, which is the part that usually fails first on machines like this.
It focuses on three main things:
- Built to last, with the voltage regulators kept in the airflow
- Reliable 24/7 performance
- Easy setup and use

Harlo Labs: hands on with the BS-2
BS-2 vs NEXUS S1 vs Thor P2
Three desk miners in the same class. The BS-2 gives up a terahash and a half to the other two, and costs a lot less per terahash than either.

The NEXUS S1 is the more efficient machine and it hashes harder. The BS-2 is the cheaper way onto the same silicon, water cooled, with the power supply in the box. Pick on what you are optimising for.

Efficiency
- The part that fails first, moved On machines like this the component that goes is almost always the voltage regulator. On the BS-2 the regulators sit on the back of the board, in the path of the fan. Measured at the factory: 53 degrees back there against 62 on the old front mounted layout.
- Water cooled, not just fanned A closed loop block and radiator carry the heat off 2 BM1373 chips, which is what lets the unit hold 8.5 TH/s without cooking itself.
- A real supply in the box A Meanwell power supply and a mains cord matched to your address. The supply is already fused.
- Straight SHA-256 Mines Bitcoin, solo against your own node, on an open solo pool, or on a regular pool. Ethernet on board, plus WiFi on 2.4 GHz.
