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.

Running a solid 13.8 TH/s, and the water cooling keeps it whisper-quiet even in my hot São Paulo apartment. The app shows live hashrate and power draw, and setup was plug-and-play. Best hydro miner I've owned.
The 13.8T hydro version is a beast. Temperatures stay low with zero throttling. The OLED screen and app remote control make monitoring effortless. Fast shipping to the US.
Quiet and efficient. Runs at 13.8 TH/s with a cool chip temp. The app works great on iOS. Only wish the cable were a bit longer. Overall very happy.
Excellent miner. The water cooling really shows — the fan is almost silent, and I control it remotely from my phone anywhere in Paris. Mining rewards are consistent. Highly recommended.
Solid 13.8 TH/s performance. Setup was easy via WiFi. The app interface is clean and shows everything. Minor point: the fan light is a bit flashy. Otherwise perfect for home use.
Impressive hydro cooling — runs cool even in summer heat. Hashrate is stable at 13.8T. Remote control via Bluetooth/WiFi works flawlessly. Great value for a small home miner.
Good miner, easy to set up, and the app is user-friendly. Water cooling keeps noise down. Hit my first block after a few weeks. Only 4 stars because delivery to Brazil took a while.
Very satisfied. The 13.8 TH/s hydro model runs silently and cool. OTA updates and remote configuration work well. A perfect addition to my small farm.
Beast of a miner. 13.8T stable, low power, and a great app with block query. Hydro cooling is a game changer in a closet setup. Worth every penny.

The NerdQAXE Rev 3.1 13.8T Hydro is designed to deliver approximately 13.8 TH/s when operating under suitable power, cooling and firmware conditions. Actual sustained hashrate may vary with ambient temperature, pool latency, firmware version and operating settings.
For installation planning, allow for up to approximately 240W for the miner, plus normal conversion losses from the power supply and any power required by the pump or radiator fans. Measurements taken at the wall may therefore differ from the value shown in the miner interface.
2. Is the NerdQAXE Rev 3.1 13.8T Hydro quiet enough for home use?+
The hydro-cooling system reduces the need for the high-speed fans commonly used by conventional ASIC miners, making this model more suitable for home, office or desktop mining environments. However, it should not be considered completely silent.
The pump and radiator fans will still produce some sound, and the miner will release heat into the room. Final noise and temperature levels depend on fan speed, room temperature, ventilation and operating settings. For comfortable continuous use, place the miner in a ventilated area rather than an enclosed cabinet.
3. Does the miner arrive ready to run, and what should I check before ordering?+
The NerdQAXE Rev 3.1 13.8T Hydro is supplied as a configured hydro-cooled mining unit. Power supplies, regional AC cables and cooling accessories may vary depending on the selected configuration and shipping destination.
Before placing your order, please confirm whether the chosen option includes the power supply, regional power cable, pump, radiator, fans, tubing and other required accessories. Customers who need a complete ready-to-run package should contact Ustarminer before ordering to confirm the exact package contents and plug type.
4. How difficult is it to set up and maintain the NerdQAXE Rev 3.1 13.8T Hydro?+
Basic network and pool configuration is managed through the miner’s web interface. The usual process is to power on the unit, connect to its temporary Wi-Fi network, enter your 2.4 GHz Wi-Fi credentials, and then add your Bitcoin wallet address and compatible mining-pool information.
Before powering the miner, check that the cooling loop is properly connected, the pump is operating and coolant is circulating normally. Do not operate the pump without coolant. During regular use, inspect the tubing, fittings, radiator airflow and coolant condition, and monitor both ASIC and voltage-regulator temperatures through the interface.
Users can adjust supported frequency and voltage settings, but stock settings are recommended for initial operation. Overclocking can increase power consumption, heat and hardware stress and may affect warranty coverage.
5.Can the NerdQAXE Rev 3.1 13.8T Hydro mine Bitcoin solo, and does 13.8 TH/s guarantee rewards?+
Yes. The NerdQAXE Rev 3.1 13.8T Hydro uses the SHA-256 algorithm and can connect to a compatible Bitcoin solo-mining pool or supported standard mining pool. Its approximately 13.8 TH/s target hashrate provides significantly more hashing power than smaller entry-level desktop miners.
Solo mining remains probability-based, however, and no miner can guarantee that it will find a Bitcoin block or generate regular income. Results depend on Bitcoin network difficulty, uptime, pool configuration, latency and luck. This product is best suited to users who value home mining, open-source hardware, Bitcoin network participation and the possibility—but not certainty—of finding a solo block.
