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 “Bitaxe NerdQAXE Rev 3.1 12T.”

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 air-cooled 12 TH/s configuration. Buyers who require confirmation of the board marking, power supply or production batch should contact UStarMiner before ordering.

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.

The miner is rated at approximately 240W, 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.

UStarMiner lists the NerdQAXE Rev 3.1 at approximately 50 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 240W, 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.

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.
