NerdMiner NerdQaxe+ Hydro 4.8T

The NerdMiner NerdQaxe+ Hydro (often listed as NerdQaxe++ Hydro or similar variants) is a compact, hydro-cooled (liquid-cooled) open-source Bitcoin solo miner, part of the popular Bitaxe/NerdMiner ecosystem. It’s designed for home enthusiasts, hobbyists, and “lottery-style” solo mining — running on the SHA-256 algorithm to mine Bitcoin (BTC), with a tiny but real chance of solving a full block for the current ~3.125 BTC reward plus fees.

This hydro version uses advanced water cooling for ultra-quiet operation, better thermal stability, and consistent performance compared to air-cooled models, making it ideal for desk setups, bedrooms, or offices without the fan noise or excess heat.

Here are some clear product views showing the sleek, compact black (or white) casing, hydro cooling setup, ports, and small display:

Key Specifications

• Hashrate: 4.8 TH/s (terahashes per second; some batches report 4.3–5.3 TH/s depending on tuning/overclock)
• Power Consumption: 60–90W (typically ~75W; varies by source and mode)
• Efficiency: ~15–19 J/TH (highly efficient for its class, using 4x BM1370 ASIC chips)
• Algorithm: SHA-256 (Bitcoin, plus BCH/BSV compatibility)
• Cooling: Sealed hydro/liquid cooling (water-based, no external loop needed in most models; ultra-quiet at ~30 dB or less)
• Noise Level: Extremely low/silent (major upgrade over fan-cooled versions)
• Dimensions: Very compact (~24 × 16 × 13 cm or smaller; palm-sized in some descriptions)
• Weight: ~0.4–0.6 kg
• Connectivity: 2.4GHz Wi-Fi (plug-and-play setup via web interface or app)
• Display: Small color LCD (e.g., 1.9-inch) for real-time hashrate, temp, network status, and earnings
• Other Features: Open-source firmware (highly customizable); supports solo mining (lottery odds) or pool mining; includes PSU in most bundles; beginner-friendly but tweakable for DIY enthusiasts

Features and Use Case

This is a step up from basic single-chip NerdMiners or the air-cooled NerdQaxe++, thanks to the liquid cooling which keeps chips cooler for sustained performance without throttling. It’s perfect for home use: silent, low-heat output (great as a “warm desk gadget” without being a full heater), and energy-efficient. Many users run it 24/7 for fun, learning, network decentralization, or the thrill of solo mining (your odds are astronomical, but someone wins eventually!).

Setup is easy — connect to Wi-Fi, configure pool/solo via browser, and monitor via the built-in screen. Open-source nature allows firmware flashes for custom features.

Profitability and Pricing

At ~75W, monthly electricity cost is low (~$10–15 at average US rates of $0.15/kWh; even less in low-cost areas). Daily earnings are tiny in pools (fractions of a cent), but it’s about the experience rather than profit. Solo mode is pure lottery.

Pricing typically ranges from $250–$450 USD (often ~$300–$400 with PSU), available on Amazon, eBay, SoloSatoshi, Zeus Mining, and other crypto shops. Stock fluctuates with new batches/revs (e.g., Rev 6.1 pushes higher hashrates in some variants).

Compared to the earlier Canaan Avalon Nano 3S (6 TH/s air-cooled, similar home focus) or industrial beasts like the Bitmain L11, this is a fun, quiet, efficient middle-ground for hobbyists. If you’re in Secaucus, NJ (current date Jan 19, 2026), check local power rates for exact calcs!
