HOME MINING · SHA-256 · HYDRO-COOLED · 7nm

NerdOctaxe Rev3.1 Hydro

13.8 TH/s · 230W · Water-Cooled · 8× BM1370

Run Cooler. Mine Longer. Hash Stronger. The NerdOctaxe Rev3.1 Hydro is a premium, water-cooled Bitcoin Home Miner, engineered for maximum sustained hashrate with industry-leading thermal efficiency. Powered by 8× BM1370 7nm ASIC chips, it delivers a continuous 13.8 TH/s of SHA-256 computing power at 230W.

The integrated water cooling system reduces chip temperatures by approximately 10°C and power consumption by 10–15W compared to air-cooled models — enabling more stable, quieter, and longer-lasting operation. Built on the proven Rev3.1 PCB with upgraded 6-phase VRM and TPS53667 voltage controller, this is the most powerful and thermally refined home Bitcoin miner in the Nerd Octaxe lineup.

Frequently Asked Questions

What makes the Hydro version better than the air-cooled NerdOctaxe?

The water cooling system reduces chip temperatures by approximately 10°C and power consumption by 10–15W compared to the air-cooled Rev3.1. This allows the miner to sustain a higher 13.8 TH/s hashrate continuously, run quieter, and experience significantly less thermal stress — extending the lifespan of the ASIC chips and VRM components.

How much electricity does it consume monthly?

At 230W continuous draw, the NerdOctaxe Hydro consumes approximately 5.5 kWh per day. At an average electricity rate of $0.20/kWh, that works out to approximately $33 per month. The efficiency of ~16.7 J/TH is competitive with industrial-grade miners, and the water cooling helps reduce waste heat significantly.

Does the water cooling require maintenance?

The water cooling system is pre-installed and sealed for low-maintenance operation. Under normal conditions, it requires no coolant refills or tube replacements. Keep the unit in a well-ventilated area and ensure the radiator fan is free from dust buildup for optimal long-term performance.

Can I run it at lower power for quieter operation?

Yes. Through the AxeOS web dashboard, you can reduce the frequency to achieve ~9.6 TH/s at approximately 160W for a quieter, eco-friendly profile. You can also tune anywhere between 9.6 and 13.8 TH/s depending on your noise and power budget. The water cooling keeps temperatures low across all profiles.

How does the NerdOctaxe compare to a NerdQaxe++?

The NerdQaxe++ uses 4× BM1370 chips and delivers 4.8 TH/s at ~80W. The NerdOctaxe Rev3.1 Hydro doubles the chip count to 8 and delivers 13.8 TH/s at 230W with water cooling — roughly 2.9× the hashrate. Both share the same AxeOS firmware, web dashboard, and community support. The Hydro version additionally offers superior thermal performance and quieter operation.
