Cooldragon

Cooldragon Antminer KS5 Pro 21Th 3150W mining hardware

SKU CH-YJBS-SAH71

Bitmain-built Kaspa ASIC miner delivering 21 Th/s at 3150 W with dual fans rated at 75 dB

  • 21 Th/s hashrate for Kaspa mining
  • 3150 W power draw for energy planning
  • 75 dB noise level for site assessment
  • 5–45 °C operating range for environment control
  • 195 × 290 × 430 mm footprint for rack layout

Targeted Kaspa ASIC miner

The Cooldragon Antminer KS5 Pro delivers a 21 Th/s hash rate for the kHeavyHash algorithm used by Kaspa. It connects via Ethernet and draws 3150 W from the supplied power input. The unit is built for operators who need dedicated KAS coin mining hardware in a standalone enclosure.

Dual-fan cooling and fixed firmware

Two integrated fans move air through the 195 x 290 x 430 mm chassis to keep internal temperatures between 5 and 45 °C. The firmware is locked to the Kaspa algorithm, so the device cannot be repurposed for other coins or algorithms without manufacturer support.

Environmental and power constraints

Operation is rated for 5 to 45 °C ambient temperature and 5 to 95 % relative humidity, limiting deployment to climate-controlled spaces. The 3150 W power draw requires a compatible high-capacity circuit and PDU, and the 75 dB noise level makes the unit unsuitable for office or residential settings.

Questions about this item

Does the unit ship with a power supply that can deliver 3150 W?

The miner draws 3150 W; a compatible high-wattage PSU must be sourced separately.

Can the 75 dB noise level be reduced for home use?

75 dB is loud — plan for a dedicated ventilated space or sound-dampening enclosure.

What ambient temperature range does the hardware tolerate?

Operating range is 5 °C to 45 °C with humidity between 5 % and 95 %.
