Frequently Asked Questions
How quiet is the NerdQaxe++ Hydro compared to air-cooled miners?
The Hydro operates at approximately 30 dB — significantly quieter than the air-cooled NerdQaxe++ and most desktop computers. The Snowman KS120 sealed liquid cooling replaces high-speed fans with a single quiet PWM radiator fan. Many users run it on their nightstand or living room shelf 24/7 without disturbance.
Do I need technical skills to set it up?
Not at all. The NerdQaxe++ Hydro arrives fully assembled and pre-flashed. Connect the power supply, power on, and connect to the "NerdAx_XXXX" WiFi network from your phone or computer. Enter your home WiFi credentials and mining pool details through the web interface, and mining begins within minutes.
How much electricity does it consume?
At stock settings, the NerdQaxe++ Hydro draws approximately 72–80W — about the same as a single incandescent light bulb. At an average electricity rate of $0.20/kWh, that works out to approximately $11–14 per month. The efficiency of ~15–16.5 J/TH is competitive with industrial-grade miners.
Does the liquid cooling require maintenance or refilling?
No. The Snowman KS120 is a fully sealed, closed-loop system — similar to AIO CPU coolers used in desktop PCs. There's no need to refill coolant, replace tubing, or perform any maintenance. The sealed design eliminates leak risk under normal use, making it safe for continuous 24/7 residential operation.
What's the difference between NerdQaxe++ Hydro and the standard NerdQaxe++?
Both models use the same 4× BM1370 chip design and deliver ~4.8 TH/s at ~75W. The key difference is cooling: the standard NerdQaxe++ uses dual-fan air cooling, while the Hydro version uses a sealed closed-loop liquid cooling system with a Snowman KS120 radiator. The Hydro runs significantly quieter, maintains lower chip temperatures, and includes RGB lighting. Choose the Hydro for maximum silence and thermal stability.
