VolcMiner D3 (20GH)

The VolcMiner D3 is a purpose-built Scrypt ASIC that delivers 20 GH/s while drawing 3580 W, achieving an energy efficiency of 0.179 J/MH and targeting Litecoin and Dogecoin mining with clinical precision; its robust chassis and optimized thermal layout, including four high-speed fans, sustain continuous 24/7 operation and position the unit among the top-performing Scrypt miners for 2026, while Ethernet connectivity provides reliable pool access and remote management, the 75 dB noise level mandates placement in dedicated, ventilated facilities rather than living spaces, and operators should provision proper power distribution, cooling infrastructure and UPS protection to secure uptime and chip longevity-together the performance, efficiency and build quality make the D3 a deliberate, industrial-grade choice for large-scale Scrypt mining where predictable returns and long-term operational stability are required.

VolcMiner D3 is a stripped-down workhorse for Scrypt coins, designed to mine Dogecoin and Litecoin without theatrics. It delivers 20 GH/s while pulling 3580 W from the wall. That translates to 0.179 J/Mh of efficiency. Four high-speed fans force air through a rugged chassis and keep the unit stable across a 5–45 °C operating range. Noise runs about 75 dB. Place it in a dedicated, ventilated room. Ethernet provides a steady connection to pools and remote controls. The build is industrial and meant for continuous 24/7 duty. It won’t forgive sloppy infrastructure. Provision proper power distribution, cooling and UPS backup to protect uptime and chip life. In exchange you get predictable scaling, efficient power use and a miner that trades glamour for long-term returns.

Scrypt is a cryptographic hash function that serves as the backbone of NiceHash proof-of-work consensus mechanism. This algorithm processes input data of any length and produces a fixed hash value, ensuring security and integrity in the mining process.
