AI Video Summary:
This video explores the Nerd QAX line of home Bitcoin miners, which features four ASIC chips instead of the single chip found in standard BitAxe miners. It compares three specific variants—the Nerd QX Plus Hydro (water-cooled) and two air-cooled versions of the Nerd QX++—evaluating their hash rates, thermal management, and noise levels.
Hash Rate & Hardware:
Nerd QX Plus: Uses four BM1368 chips (from the Bitaxe Supra), delivering ~2.5 TH/s.
Nerd QX++: Uses four BM1370 chips (from the Bitaxe Gamma), delivering ~4.9 TH/s at stock settings. [01:12, 01:25]
Revision 6 Improvements: The newer "Revision 6" of the QX++ introduces an XT30 power connector (upgrading from a barrel jack), providing more headroom for overclocking (up to 15 amps). It also features improved PCB trace layouts that allow voltage regulators to run cooler without the need for external heat sinks. [02:48, 03:35]
Hydro vs. Air Cooling:
Hydro: Uses a water block and radiator fan. At 15% fan speed, it is very quiet (39.3 dBA), but at 100% speed, it becomes quite loud (47.3 dBA).
Air-Cooled (Rev 6): Surprisingly, the air-cooled Revision 6 was quieter than the Hydro model in practical testing. With its dual-fan setup (front and rear) running at 50% speed, it measured just 35.8 dBA—virtually silent and suitable for an office environment. [06:49, 12:32]
Thermal Performance: The water-cooled Hydro model excels at keeping the ASIC chips very cool (~49.9°C at 15% fan speed). However, for air-cooled models, adding the optional rear fan to the QX++ significantly reduces voltage regulator temperatures (by up to 7.5°C) and allows both fans to run slower and quieter. [07:07, 11:31]
Recommendation: The Nerd QX++ Revision 6 (Air-Cooled) is highlighted as the best balance of hash rate, value, and noise. Its native efficiency and quiet operation make it more practical for most home users than the Hydro version, which prioritizes aesthetics (LEDs) and potential overclocking headroom. [15:01, 15:19]
