Notes
(1) The hashrate value, power on wall, and power efficiency on wall are all typical values. The actual hashrate value fluctuates by ±3%, and the actual power on wall and power efficiency on wall fluctuate by ±5%.
(2) Caution: Wrong input voltage may cause server damaged.
(3) The noise is loudest when the fan is under maximum RPM(rotation per minute).
(4) When the server is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1℃ for every increase of 300m.

NerdMiner NerdOCTAxe Rev 3.1 Hydro
The NerdMiner NerdOCTAxe Rev 3.1 Hydro is a compact SHA-256 ASIC miner designed for Bitcoin solo mining, compatible pool mining, technical learning, and home-based mining experiments.
Powered by eight BM1370 ASIC chips, it delivers up to approximately 12 TH/s while consuming around 190W under typical operating conditions. The hydro-cooling design is intended to improve heat transfer and reduce the dependence on high-speed air cooling compared with conventional compact miners.
Its relatively low total power demand makes it easier to deploy than a full-size industrial Bitcoin miner. However, users must confirm that the required water-cooling equipment, power supply, network connection, and accessories are included with the selected product option.
Bitcoin Solo Mining
Solo mining differs from ordinary pool mining. Instead of receiving small proportional payouts from a mining pool, a solo miner attempts to find a valid Bitcoin block independently or through a solo-mining pool.
Finding a block with a compact miner is statistically unlikely, and the time required cannot be predicted. The NerdOCTAxe should therefore be viewed primarily as a hobby, educational device, or probability-based solo-mining machine rather than a source of guaranteed income.
Users who prefer smaller and more consistent payouts may configure a compatible standard mining pool instead, subject to firmware and pool support.
NerdOCTAxe Rev 3.1 Hydro vs NerdOCTAxe Rev 3.1
Both models deliver 12 TH/s SHA-256 hashrate for Bitcoin solo mining. The NerdOCTAxe Rev 3.1 Hydro is more efficient with 190W power consumption, while the standard NerdOCTAxe Rev 3.1 is a simple and affordable choice for home miners.

FAQs
-
What Is The Lifespan Of This Mining Machine?
The lifespan of mining hardware is influenced by usage intensity, environmental factors like temperature, humidity, and dust. Proper maintenance and optimal conditions can significantly extend its longevity.
-
How Does Electricity Cost Impact Profitability?
Electricity costs play a crucial role in mining profitability, as high rates can quickly offset profit. Therefore, it is vital to access local electricity costs to determine if mining is viable. With high electricity costs and high liquidity of digital assets, investing in an energy-efficient miner becomes even more important.
-
Does solo mining guarantee a Bitcoin reward?
No. Solo mining is probability-based, and finding a valid Bitcoin block with a compact miner is statistically unlikely.
-
Does this miner generate a lot of heat or noise?
No, it runs cooler and quieter than large industrial miners, making it suitable for indoor use.
-
Is the NerdOCTAxe Rev 3.1 Hydro beginner-friendly?
Yes, it features simple setup, stable firmware, and plug-and-play operation.

It uses standard low-wattage power input suitable for home outlets.
-
Can the NerdOCTAxe Rev 3.1 Hydro run 24/7?
Yes, it is built for continuous, long-term stable mining.
-
Is this miner profitable at higher energy prices?
Its low power draw improves ROI potential even in regions with moderate electricity costs.
-
Does BT-MINERS provide warranty and delivery support?
Yes, BT-MINERS offers secure checkout, fast worldwide shipping, and full warranty assistance.
