Estimate for 13.8 TH/s at today’s Bitcoin difficulty, block reward and BTC price (mempool.space, CoinGecko; updated 2026-11-01 00:55 UTC), before pool fees. Power cost = watts × 24 h × your price per kWh.

Solo lottery

Solo mining odds: your chance to hit a Bitcoin block

Mining solo, this miner’s 13.8 TH/s buys a ticket in every block draw. A block is found about every 10 minutes, and the miner who finds it keeps the whole reward.

The prize: one block

≈ 15 of these miners together would give a 1 in 100 chance a year.

Every 10 minutes is a fresh draw; luck does not build up. Solo mining is a lottery, not an income: most solo miners never find a block.

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.

Key Features
8× BM1370 7nm ASIC Chips
Same S21 Pro-class chips used in industrial miners. Eight chips working in parallel deliver a massive 13.8 TH/s of SHA-256 hashpower for home mining.
Water Cooling System
Integrated hydro cooling reduces chip temp by ~10°C and power draw by 10–15W. More stable, quieter, and longer lifespan than air-cooled models.
⊕
Solo & Pool Mining
Mine via CKPool, Public Pool, or your own Bitcoin node for the full 3.125 BTC block reward. Or join any Stratum V1 pool for consistent payouts.
⚙
Open-Source AxeOS Firmware
WiFi plug-and-play setup via web dashboard. Monitor your swarm of miners from one panel. Fully customizable open-source firmware with active community.
Color LCD Display
LILYGO T-Display S3 1.9" color screen with 2 programmable buttons shows hashrate, ASIC temperature, power usage, efficiency, and Bitcoin price live.
Rev3.1 Upgraded PCB
6-phase VRM power supply, TPS53667 voltage controller, optimized PCB layout for even heat distribution, improved stability under continuous high-load operation.
Water Cooling Advantage

Water cooling enhances performance across every metric — enabling continuous and efficient output of 13.8 TH/s computing power:

~10°C lower chip temps 10–15W less power draw More stable operation Quieter than air-cooled Longer hardware lifespan Sustained 13.8 TH/s output
Recommended maximum operating temperature: ≤ 70°C

Bitcoin Lottery Mining
Every hash is an independent chance at the full 3.125 BTC block reward (currently worth over $300,000). At 13.8 TH/s, the NerdOctaxe Hydro offers the highest solo mining odds of any home miner — roughly ~14× better odds than a single Bitaxe and ~3× better than a standard NerdQaxe++. Real open-source miners have already won confirmed blocks on CKPool and Public Pool.

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.
