Antminer S21Pro Water Cooling Kit – Aluminum Cooling Plates for Heat Dissipation

Antminer S21 Pro Water Cooling Kit – Multi-Channel Aluminum Cooling Plates

Convert your air-cooled Antminer S21 Pro into a liquid-cooled unit with this aluminum water cooling kit. The multi-channel plate design conducts heat away from the hash board ASIC chips and into a closed-loop coolant circuit, delivering 40% faster heat removal compared to stock fans and reducing acoustic noise by up to 70%. The result is a miner that runs cooler, quieter, and with more stable hash rates — especially in high-ambient environments where air cooling alone causes thermal throttling.

Eliminate Thermal Throttling on the S21 Pro

The S21 Pro's high power density means ASIC junction temperatures can climb quickly under air cooling, triggering firmware-level frequency reduction to protect the chips. A water cooling plate keeps chip temperatures well below the throttle threshold, allowing the miner to sustain its full advertised hash rate around the clock. In farms where ambient temperatures regularly exceed 35 °C, water cooling often pays for itself within weeks through the recovered hash output.

Installation and Leak Prevention

The kit includes 8 mm pneumatic plugs and pipe caps (random quantity) for connecting to your existing coolant loop or building a new one. Before filling the loop, pressure-test the circuit at 1.5× operating pressure with the plugs installed to verify every joint is sealed. Once confirmed, fill with distilled water or a dedicated coolant mix, bleed the air, and power on. Pair the kit with a fan speed simulator so the miner firmware does not fault on missing fan RPM signals after the stock fans are removed.
