Hydro-Cooling Systems
Hydro-cooling moves heat off the chip directly into a closed water loop instead of relying on airflow, cutting noise, extending hardware life, and letting racks run denser than air-cooled rows allow.
Zyrix supplies complete hydro-cooling systems, factory-matched hydro-cooled miners, and the radiators and cabinets needed to run them at farm scale.
How hydro-cooling works
In a hydro-cooled ASIC, a water block sits directly on the hashboard chips in place of a heatsink and fan array. A closed liquid loop carries heat away from the block to an external radiator, where it's rejected to ambient air or, in larger installations, to a dry cooler. Because water conducts heat far more efficiently than air, chips run cooler and more consistently, which supports higher clock settings and reduces thermal throttling in hot climates.
H-Series, H20-Series, and HC-Series
Our H-Series covers standalone hydro-cooling radiators and cabinets sized for small-to-mid rack counts, suited to buyers running a handful of hydro miners without a full facility-level cooling loop. The H20-Series steps up to higher-throughput water-cooling units built for continuous multi-rack operation, including the AP-M2-class radiator supporting two miners per unit. The HC-Series is our facility-scale hydro-cooling cabinet range, designed to interface with a farm's central dry cooler and pump skid for container or warehouse deployments.
Popular hydro-cooled miners in our shop include the Antminer S19 XP Hyd (473Th), Antminer S19 Pro Hyd (184Th), Antminer S19 XP+ Hyd (293Th), Antminer S21+ Hydro (395Th), and the Antminer S21 XP+ Hyd (500Th/s). Scrypt-algorithm buyers can also pair the Antminer L11 Hyd 6U family with the same radiator infrastructure.
Dry cooler and pump sizing
Facility-scale hydro deployments reject heat through an outdoor dry cooler rather than ambient air alone, so sizing the dry cooler and pump skid to the site's total kW load and local climate is critical. Undersized dry coolers cause loop temperature creep during peak ambient hours, which throttles hashrate even though every individual miner is functioning correctly. We size dry cooler and pump capacity against your planned rack count, ambient design temperature, and target inlet water temperature before recommending an H20 or HC-Series configuration.
Noise, density, and warranty implications
Because hydro-cooled miners have no cooling fans, site noise drops dramatically compared to an equivalent air-cooled row, which matters for near-residential or office-adjacent deployments. Hydro cabinets also allow denser rack layouts than air cooling, since airflow clearance between units is no longer a constraint.
Hydro-cooled units carry the same manufacturer warranty structure as air-cooled equivalents, but water-loop integrity is the buyer's responsibility once installed: leaks or contaminated coolant caused by improper installation are typically excluded from hashboard warranty claims, so we recommend a professional loop commissioning check before continuous operation.
Frequently asked
- Do hydro-cooled miners need a separate water loop per unit?
- No, in facility-scale HC-Series and H20-Series setups, multiple miners share a common loop connected to a central dry cooler and pump skid, rather than each having an independent radiator.
- Can I retrofit an air-cooled miner to hydro-cooling?
- Generally no. Hydro-cooled models use a dedicated water-block chassis design; air-cooled and hydro variants of the same chip are different physical products, not interchangeable via aftermarket conversion.
- How much noise reduction should I expect?
- Hydro-cooled miners have no internal fans, so noise at the unit is limited to the water pump and external dry cooler fans, typically far below the noise level of an equivalent air-cooled row.
- Does hydro-cooling affect the manufacturer warranty?
- The chip and board warranty terms are unchanged, but coolant loop leaks or contamination from improper installation are generally not covered, so professional commissioning is recommended.
