Buy Hydro-Cooled ASIC Miners — Liquid-Cooled Hardware for Data Centers

Hydro cooling replaces traditional fan-based air cooling with a closed-loop water circuit. Coolant flows through internal cold plates inside the ASIC, absorbing heat directly from the chips, then transfers it to an external radiator or CDU for rejection. This delivers dramatically lower noise (~40 dB vs 75-85 dB) and better thermal efficiency.

The S23 Hydro (580 TH/s) delivers nearly double the hashrate of the S21 Hydro (335 TH/s) with improved efficiency. The S23 Hydro costs more upfront but earns faster ROI. The S21 Hydro remains a strong option for smaller deployments. Both ship with free DDP delivery.

Hydro miners operate at approximately 40-50 dB — comparable to a quiet conversation. Air-cooled ASICs produce 75-85 dB. This makes hydro miners suitable for office environments, residential areas and noise-sensitive locations where air-cooled miners are impractical.

A CDU (Coolant Distribution Unit) is the central pump and heat-exchange unit in a hydro cooling loop. It circulates coolant through your miners via manifolds and routes heated coolant to an external dry cooler for heat rejection. You need a CDU when running 3+ hydro miners. Browse our mining equipment for CDU options.

A basic hydro loop requires: hydro miners, manifolds with quick-disconnect fittings, a CDU or pump, a dry cooler/radiator, hoses and deionised water with corrosion inhibitor. Contact our team for a free system design consultation — we specify every component for your deployment size.

Hydro systems need coolant chemistry testing every 3-6 months, visual inspection of fittings for leaks, pump performance checks and annual corrosion inhibitor replenishment. Clean radiator fins seasonally. Well-maintained systems run reliably for years. See our FAQ for detailed maintenance schedules.

Hydro cooling typically improves overall system efficiency by 5-15% versus air-cooled equivalents. The gains come from eliminating fan power consumption and maintaining lower, more stable chip temperatures. Combined with hosting at $0.07/kWh, this significantly improves mining economics.

Hydro cooling systems can achieve PUE (Power Usage Effectiveness) of 1.02-1.05, meaning 98% of electricity goes to actual mining. Air-cooled setups typically achieve PUE of 1.15-1.30. In cold climates with free cooling, hydro PUE can approach 1.01 for extended periods — maximising revenue per kWh.

Small hydro setups (1-3 miners with a radiator) are feasible at home if you have a dedicated 240V circuit, space for the radiator and basic plumbing skills. For larger deployments, professional hosting is more practical. Contact us for help sizing a home hydro system.

Size your radiator at 120-130% of total ASIC power draw. Three Antminer S21 Hydro units at 5.5 kW each = ~16.5 kW heat load, requiring a 20-22 kW radiator. For hot climates (sustained 35C+), increase to 140-150%. Browse our mining equipment for compatible radiators.

Yes — Lian Li mining containers support Bitmain Hydro series integration with pre-run coolant distribution infrastructure and compatible quick-disconnect fittings. Contact our team for specific container-to-miner compatibility confirmation and adaptor requirements.

The Antminer S21 Hydro draws ~5,500W and the S23 Hydro draws ~4,700W. Running 24/7, an S23 Hydro costs approximately $240/month at the MillionMiner hosting rate of $0.07/kWh. Hydro models use less total system power than air-cooled equivalents because they eliminate fan energy consumption.

Yes — all hydro miners ship with free worldwide DDP delivery. No customs duties, no import taxes. We package hydro units with extra protection for the water fittings. In-stock models dispatch within 1-3 business days.

Bitmain Hydro miners carry a 180-day manufacturer warranty under normal operating conditions. CDU and cooling infrastructure typically carry 12-month warranties. For miners with MillionMiner hosting, we handle all warranty claims and on-site repairs. See our FAQ for details.

Yes — our hosting facilities fully support hydro-cooled miners with dedicated hydro infrastructure. Same $0.07/kWh rate, 99.9% uptime and real-time monitoring. Purchase your hydro miner and add hosting in a single order.

Yes — MillionMiner provides B2B bulk pricing with dedicated account managers for large hydro deployments. Contact our B2B team with model, quantity and destination. We offer combined purchase + hosting packages and full system design for fleet orders.

Hydro cooling circulates water through internal cold plates inside purpose-built ASICs (e.g. Antminer Hydro series). Immersion cooling submerges standard air-cooled ASICs in dielectric fluid. Hydro is simpler to maintain; immersion achieves higher density but requires specialised tanks and fluid management.

Yes — Bitmain and Lian Li offer hydro-optimised containers with integrated manifolds, CDUs and dry coolers. This is the most efficient deployment format for 50+ hydro miners. Contact us for container-based hydro system design and pricing.

Hydro systems manage heat effectively up to 40-45C ambient with properly sized dry coolers. In sustained heat, use oversized radiators (140-150% capacity) and water-glycol coolant. PUE will increase slightly but remains far better than air cooling in the same conditions.
