Home SHA-256 Miner with Water Cooling

The Stellapex NerdQaxe++ Hydro delivers 4.8 TH/s from four BM1370 ASIC chips while drawing 75 W from a 100-240 V AC adapter. It connects over 2.4 GHz WiFi and weighs 830 g in a 180x130x175 mm enclosure. The unit targets Bitcoin, Bitcoin Cash, Bitcoin SV and other SHA-256 coins for solo or lottery mining at home.

Sustained Load Behaviour

At continuous operation the miner maintains its rated 4.8 TH/s with a power efficiency of 0.016 J/GH across the 5-45 °C temperature range. The water-cooling loop keeps chip temperatures stable during 24/7 duty cycles without thermal throttling. Firmware updates are supported through the open-source platform for ongoing optimisation.

Thermals Noise and Power Draw

The closed-loop water cooling limits acoustic output to 40 dB in typical room conditions. Power draw remains at 75 W from the wall adapter while the system operates within 5-95 % relative humidity. The compact 180x130x175 mm footprint allows desk or shelf placement without additional ventilation infrastructure.

Questions about this item

How loud is the water-cooled Stellapex NerdQaxe++ Hydro when it runs continuously at 4.8 TH/s?

The miner operates at a quiet 40 dB, making it suitable for home or office environments without disruptive fan noise.

Does the Stellapex NerdQaxe++ Hydro need any extra equipment beyond the included AC adapter and cable to start mining?

Only a 100-240 V mains socket and a 2.4 GHz Wi-Fi network are required; the package already contains the power adapter, AC cable and the miner itself.

Will the Stellapex NerdQaxe++ Hydro work alongside my older SHA-256 USB stick miners on the same pool?

Yes, it mines the same SHA-256 algorithm and connects via Wi-Fi, so it can point to any pool that accepts BTC, BCH or BSV shares from legacy devices.
