The Antminer S21XP liquid cooling board upgrade kit replaces the original air-cooled heatsink, helping S21XP miners upgrade from air cooling to efficient liquid cooling. The S21XP water cooling board features an integrated precision water-cooling plate with a flow channel design, resulting in faster heat conduction and more even heat dissipation. It completely solves pain points of the S21XP, such as high-temperature throttling under high load, hashrate fluctuations, excessive noise, and dust accumulation and aging. It is suitable for home-based silent mining, small mining farms, and high-density data center cluster deployments, supporting stable 24/7 full-load operation, reducing overall power consumption while significantly extending the lifespan of the miner hardware.
In addition, we will also give away a random number of 10mm pneumatic plugs and pipe caps, which can be used to plug the water cooling plate quick connector or bellows when replacing the water cooling plate or repairing the hash board to avoid leakage and waste of water cooling liquid.
