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 NerdQaxe++ Hydro
The NerdMiner NerdQaxe++ Hydro is a premium 4.8TH/s Bitcoin miner designed for home users who want ultra-quiet performance and better thermal stability. With a sealed liquid-cooling system, it maintains lower temperatures than the air-cooled NerdQaxe++901, delivering more consistent efficiency during 24/7 operation. Both models offer similar power consumption at around 95W, but the Hydro version provides quieter operation, reduced heat output, and improved long-term reliability.
For users who prioritize low noise, stable temperatures, and efficient home mining, the Hydro model is the superior choice. The NerdQaxe++901 remains a great budget-friendly alternative, offering the same 4.8TH/s hashrate in a compact air-cooled design that is easy to set up and ideal for beginners.
What Is a NerdMiner?
A NerdMiner is a compact, open-source Bitcoin lottery miner designed for enthusiasts who want to learn, experiment, and participate in solo Bitcoin mining. Unlike traditional ASIC miners, a NerdMiner doesn’t aim for high hashrate or industrial profits—instead, it enters the Bitcoin “block lottery” every 10 minutes. If you get lucky, you win the full block reward (3.125 BTC) plus transaction fees.
Built on DIY hardware such as the T-Display S3, a NerdMiner offers hands-on experience with Bitcoin mining technology. Many users build or customize the device themselves, gaining a deeper understanding of SHA-256 hashing, block creation, and how Bitcoin mining works at a technical level. Whether pre-assembled or DIY, it’s a fun, educational tool that fits on any desk.
Beyond learning, a NerdMiner also carries a small—but real—chance of mining a Bitcoin block. The odds are tiny, but the excitement and educational value make it a unique project for beginners, hobby miners, and developers.
A NerdMiner is more than a gadget—it’s an opportunity to explore Bitcoin, build your own mining device, and join the global community of open-source home miners.
NerdMiner NerdQaxe++ Hydro 4.8TH/s vs NerdQaxe++901 4.8TH/s
🎯 Which One Is Right for You?
-
Choose NerdQaxe++ Hydro if you value quiet operation, thermal stability, consistent performance over long periods of mining, or if you plan to run the miner indoors for long 24/7 sessions. It’s especially suited for home miners who are sensitive to noise and heat.
-
Choose NerdQaxe++ (Air-Cooled) if you want the simplest, most plug-and-play experience — especially if you’re new to mining, just experimenting, or don’t want to deal with water-cooling maintenance. It’s a good entry point for hobby miners.
| Specification / Attribute | NerdQaxe++ Hydro (Liquid-Cooled) | NerdQaxe++ (Air-Cooled) |
|---|---|---|
| Hashrate | 4.8 TH/s | 4.8 TH/s |
| Cooling Type | Hydro-cooling / liquid cooling | Traditional air-cooling / fan cooling |
| Power Consumption (typical) | ~ 95 W on wall | ~ 72–95 W depending on variant / spec sheet (Mining Now) |
| Noise Level | Very low (quieter than air-cooled) | Low (but higher than hydro-cooled) |
| Heat / Thermal Stability | Better — liquid cooling maintains lower temperatures under load | Acceptable — relies on air circulation; may heat up more under continuous run |
| Form Factor / Setup Complexity | Slightly more complex (liquid-cooling) but still compact & home-friendly | Very simple, plug-and-play air-cooled setup, minimal maintenance |
| Ideal Use Case | Quiet home mining, 24/7 stable mining, heat-sensitive or indoor environments | Easy home mining, beginners, low-cost entry, simple plug-and-play setups |

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.
-
https://bt-miners.com/products/nerdminer-nerdqaxe901-bitcoin-miner-4-8th-s-bt-miners/
It uses a liquid-cooling system designed to keep temperatures low during continuous operation, offering more stable performance compared with standard air-cooled units.
-
Is the Hydro version quieter than the air-cooled NerdQaxe++?
Yes. Liquid cooling reduces fan noise, making the Hydro model significantly quieter and better suited for bedrooms, home offices, and other indoor environments.
-
Does the Hydro system require any special maintenance?
Only basic checks are required. Ensure the coolant level is stable, the tubing is secure, and there are no leaks. Maintenance is minimal and easy for home users.
-
Can the Hydro miner run 24/7 without overheating?
Yes. The liquid-cooling loop improves heat dissipation, allowing the miner to operate continuously with more consistent temperatures and reduced thermal stress.
-
What power consumption should I expect from the Hydro version?
The Hydro model typically draws slightly more power than the air-cooled version due to the cooling pump, but it remains low enough to run comfortably in home environments.
-
Is the Hydro version suitable for small or enclosed spaces?
Yes. Because liquid cooling reduces heat output into the room, the Hydro model performs well in smaller or warmer environments compared with air-cooled miners.
-
Does the Hydro miner produce less heat overall?
It distributes heat more efficiently and removes it from the chip faster, which helps keep the miner cooler and reduces ambient temperature impact.
-
Can beginners use the Hydro version safely?
Yes. The Hydro system is pre-assembled and designed for plug-and-play use. Beginners can operate it safely with minimal setup.
-
Does the Hydro miner support both solo and pool mining？
Yes. Like the air-cooled NerdQaxe models, the Hydro unit supports both solo mining and pool mining depending on your configuration.
-
What kind of power supply does the Hydro version require?
It uses a standard AC power adapter suitable for household outlets, making installation simple even for first-time miners.
