Warranty and service
This product includes a 180-day manufacturer warranty, starting from first power-on after setup and use.
App membership and updates
After an App membership period expires, the device continues operating independently, though some App functions may be limited. Official firmware updates will continue to improve supported functions; more App features will be released in future versions.
Important notes
Solo mining results are probabilistic. A successful block depends on network difficulty, device hashrate, operating time and chance. Block results shown on the page demonstrate the query function only; they do not guarantee a BTC reward after purchase. Selected replacement accessories are available. Contact support if an accessory is damaged. Do not flash or use unofficial firmware, as this may affect device stability and after-sales service.

Water cooling makes this 12T miner almost silent. Stable hashrate and easy WiFi setup. Great for home mining.
The hydro version runs cool and quiet. 12 TH/s stable, and the app control is excellent. Very happy with this miner.
Great hydro miner. Runs 12T quietly with low temps. The app is solid. Only minor point: it takes up a bit of space.
Excellent hydro cooling. Silent operation, stable 12 TH/s, and the app is a pleasure to use. Highly recommended.
Quiet and efficient. 12T stable, and temps stay low thanks to water cooling. Setup was easy. A very good miner.
The hydro version is fantastic. No fan noise, cool operation, stable 12 TH/s. The app monitoring is top-notch.
Good hydro miner — quiet and cool, stable 12T. The app is easy. Shipping to Brazil took some time; otherwise perfect.
Very impressed. Water cooling keeps it silent and cool. Steady 12 TH/s and flawless remote control. Great investment.
Excellent hydro miner. Runs 12T with zero noise complaints, cool temps, and a great app. Best home miner I've bought.

The eight-chip 12 TH/s model is frequently described as the “NerdOCTaxe Rev 3.1” in community discussions and third-party listings, while this product is listed by Ustarminer as the “Ustarminer Nerdoctaxe Rev3.1 12T Hydro.”
Naming can vary between manufacturers, assemblers and sellers. When comparing products, check the board revision, number of BM1370 ASIC chips, rated hashrate, power requirement and cooling configuration instead of relying only on the product name.
This listing is for the Rev 3.1 hydro-cooled 12 TH/s configuration. Buyers who require confirmation of the board marking, power supply or production batch should contact Ustarminer before ordering.
2. Will the NerdQAXE Rev 3.1 maintain 12 TH/s continuously?+
The NerdQAXE Rev 3.1 is rated at approximately 12 TH/s, but mining hashrate is not a fixed reading. Short-term performance may move above or below 12 TH/s as work is submitted to the pool.
Sustained performance depends on ASIC variation, firmware settings, input voltage, ambient temperature, fan airflow and pool latency. For an accurate assessment, review the pool-side average, accepted shares, hardware-error rate and temperatures over several hours.
The factory configuration is recommended for initial operation. Increasing frequency or voltage may raise hashrate, but it also increases heat, power demand and component stress. Damage caused by unsupported overclocking or modification may not be covered by the applicable warranty.
3. What power supply is recommended for the 12T NerdQAXE Rev 3.1?+
The miner is rated at approximately 232W, so stable power delivery is especially important. Use the supplied power supply or a compatible, high-quality unit with the correct output voltage, connector, polarity and sufficient continuous-current capacity.
A power supply should not be operated continuously at its absolute maximum rating. Additional capacity can help the PSU run cooler and handle short changes in load, but a larger PSU does not make unsafe voltage or overclock settings acceptable.
Before connecting power, inspect the cable and connector for looseness or damage. Do not combine incompatible adapters, reverse polarity or substitute a higher-voltage supply. If the miner restarts, reports power errors or the connector becomes unusually warm, shut it down and check the power system before continuing.
4. How much noise and heat does the hydro-cooled 12T model produce?+
Ustarminer lists the NerdQAXE Rev 3.1 at approximately 30–35 dB. Actual noise can vary with ambient temperature, fan speed, placement and the acoustic characteristics of the room. It is quieter and easier to install than many industrial ASIC miners, but it may still be noticeable in a bedroom or quiet office.
At approximately 232W, most of the consumed electricity is eventually released as heat into the room. The miner should be placed in an open, ventilated area with unrestricted airflow around both the intake and exhaust.
Avoid enclosed cabinets, direct sunlight and locations where hot exhaust air can return to the intake. Regularly remove dust from the fans and heatsinks, and monitor both ASIC and voltage-regulator temperatures rather than checking the ASIC temperature alone.
5. Should I choose the air-cooled NerdQAXE 12T or the 12T Hydro version?+
Choose the air-cooled version if you prefer a simpler system without a pump, coolant loop or liquid-cooling components. It is generally easier to inspect, relocate and maintain, although its fans may be more noticeable in quiet rooms.
The Hydro version may be more suitable when lower fan noise and improved ASIC heat transfer are priorities. However, it still uses a pump and radiator fans, releases heat into the room and requires periodic inspection of the cooling loop.
Both versions target approximately 12 TH/s. The better option depends on installation space, room temperature, noise tolerance and willingness to maintain a liquid-cooling system. Customers who want straightforward operation may prefer air cooling, while noise-sensitive users with a suitable installation area may prefer Hydro.
