Cooldragon Antminer KS5 20T 3000W mining hardware

Cooldragon Antminer KS5 20T for Kaspa Mining

The Cooldragon Antminer KS5 20T is an application-specific integrated circuit miner built for the Kaspa network. It delivers a hash rate of 20 Th/s while drawing 3000W of power. The unit suits operators who run dedicated mining infrastructure and can meet its electrical and environmental demands. It is not suited for casual home use or builders who need quiet, low-power hardware.

Installation Requirements and Common Issues

The miner measures 195 x 290 x 430mm and weighs 16100g, so it needs a sturdy rack or shelf and enough clearance for its two fans. Connection is via a single Ethernet port. The 3000W draw requires a high-capacity PDU and matching cables; undersized wiring is the most frequent cause of instability. The 75dB noise level makes it unsuitable for shared or residential spaces without dedicated sound isolation.

Operating Limits of the Ethernet Interface

The Ethernet link carries stratum traffic to the mining pool and handles remote management commands. Bandwidth needs are modest, but latency spikes or packet loss will reduce effective hash rate and trigger reconnects. The unit is rated for ambient temperatures from 5 to 45 °C and relative humidity from 5 to 95 % non-condensing; exceeding either range can cause thermal throttling or hardware failure.
