Suitability Matrix
| Profile | Fit? | Notes |
|---|---|---|
| Apartment miner (220 V) | ★★★☆ | Needs 32 A breaker; silent enough. |
| Garage farm (sub-10 ¢ kWh) | ★★★★ | ROI < 11 months at $0.10 kWh. |
| Colocation (hydro row) | ★★★★ | 2-U form factor stacks tight. |
| Off-grid solar | ★★☆ | Still power-hungry; pair with 15 kW array. |
Usage Notes
• Keep inlet water ≥ 20 °C to avoid condensation inside the cold-plate.
• Firmware flashes via SD card only—never push OTA updates over unstable Wi-Fi.
-
Parallel loop: two D1 Hydros can share one 3 kW dry cooler; saves ~ $300 in plumbing.
-
Pool rotation: mine LTC during high-fee windows, auto-switch to DOGE for low diff.
-
Undervolt: drop 5 % power for 2 % hash loss—great for summer heatwaves.

FAQ
Q1: How loud is VolcMiner D1 Hydro in a closed room?
In a closed 20 m² room the unit measures 50 dB at one meter—quieter than a refrigerator hum and roughly the same as a modern dishwasher on eco mode. If the door is shut and ventilation is adequate, most users describe the sound as “background white-noise” rather than intrusive fan whine.
Q2: Can VolcMiner D1 Hydro mine on 110 V power?
No. The stock power-supply is 200–240 V single-phase (or 380 V three-phase) and draws up to 35 A. Running it on 110 V would trip breakers and can damage the PSU. A step-up transformer large enough for 7.6 kW is impractical; plan for 220–240 V service instead.
Q3: Which coins are most profitable on D1 Hydro today?
With the Scrypt algorithm the machine simultaneously mines Litecoin (LTC) and Dogecoin (DOGE) via merged-mining pools. Based on the last 24 h data, DOGE contributes ~$45 while LTC adds ~$7, giving a combined gross of ≈ $52 per day at current difficulty and price
Q4: What coolant mix does the D1 Hydro use?
VolcMiner ships the unit pre-filled with a 25 % ethylene-glycol / 75 % de-ionized water mix that includes anti-corrosion and anti-algae additives. The loop is sealed; topping up is only required after long-term maintenance or if hoses are disconnected.
Q5: How long is the estimated ROI of D1 Hydro at $0.10 kWh?
At $0.10 / kWh the rig nets roughly $38.8 per day after electricity. With typical June 2025 street prices for a new 30.4 GH unit, pay-back lands around 10.7 months—faster if DOGE or LTC price spikes and network difficulty remains flat.
