Compact silent miner for home and office

The Goldshell Mini-DOGE III delivers a 650Mh/s hashrate on the KHeavyHash algorithm while drawing 400W. Its 35db noise level and small footprint make it practical for residential or office environments where louder rackmount units would be disruptive.

Dual fan cooling without integrated PSU

Two onboard fans manage thermals for the ASIC boards, allowing continuous operation at the rated hashrate. The unit ships without a power supply, so the builder must source an external PSU that can reliably provide the required wattage.

650Mh/s headroom with 400W ceiling

At the rated 650Mh/s the miner runs at its design limit of 400W, leaving no thermal or electrical margin for overclocking. Efficiency is fixed by the silicon, so higher output would demand more power and cooling than the chassis and dual fans can supply.

Questions about this item

How often will the two fans on the Goldshell Mini-DOGE III need cleaning or replacement under continuous operation?

The unit runs two fans at a rated 35 dB noise level; dust buildup is the main wear factor, so plan to clean the fan intakes every few months and replace fans only if bearing noise appears.

What component hits its limit first when the miner runs at 650 Mh/s and 400 W around the clock?

The 400 W power draw and 35 dB fan curve mean thermal headroom is the first constraint; sustained load will push the cooling system to its design envelope before the hash boards throttle.

How much heat and noise does the Goldshell Mini-DOGE III add to a room when it runs all day at 400 W?

At 400 W the miner releases roughly 400 W of heat into the space, while the dual-fan design keeps acoustic output at 35 dB, comparable to a quiet office.
