Antminer S19 Aluminum Water Block Big Board Enhanced Heat Dissipation

Antminer S19 Aluminum Water Block Big Board Kit | Laser-Cut Anodized Aluminum Hydro Cooling Plate Set with Quick Connectors for S19 Air-to-Hydro Conversion

The Antminer S19 Aluminum Water Block Big Board Kit is the complete hydro conversion kit for converting an air-cooled Antminer S19 into a hydro-cooled deployment. Replaces the OEM air-cooled heatsinks with three laser-cut aluminum water cooling plates that transfer heat from the ASIC chips directly to a coolant loop — significantly more efficient than air cooling at the same ambient temperature, opening the path to higher chip density per kW of cooling.

Built from precision laser-cut and welded aluminum for high accuracy and superior air-tightness — leak paths are the #1 cause of hydro conversion failures, and the laser-welded construction eliminates the gasket-and-screw assembly that's most prone to leaks. Enlarged internal water flow channels with multi-channel diversion technology deliver swift liquid circulation across the entire chip array, ensuring uniform cooling. Anodizing treatment provides corrosion resistance for long-term coolant exposure. Upgraded stainless steel quick connectors give stable connections and quick disassembly for maintenance.

What's in the Kit

• 3× Aluminum alloy water cooling plates — one per S19 hashboard (covers the full miner).
• 2× 1-to-3 water cooling separators — distribute coolant evenly across the three plates.
• 2 m silicone water pipe — flexible inter-plate piping.
• 2 m main water pipe — connection to external coolant loop.
• Clamps — secure pipe-to-fitting connections.
• Stainless steel quick connectors — built into the plates for tool-free disassembly.

When to Deploy the S19 Aluminum Water Block Kit

• Air-to-hydro conversion of an existing Antminer S19 fleet — keep the miners running while gaining hydro thermal margins.
• High-density facility deployment — hydro cooling enables tighter rack spacing than air cooling at the same heat output.
• Hot-climate operations — hydro cooling decouples chip temperature from facility ambient air temperature.
• Noise-sensitive deployments — hydro miners run far quieter than air-cooled (no high-RPM chassis fans).
• Heat reuse projects — capture chip heat in coolant for downstream use (district heating, agricultural drying, pool heating).

Aluminum Water Block Specifications

FAQ — S19 Aluminum Water Block Kit

Q: What's the difference between this kit and an OEM Bitmain S19 Hydro?
A: The Bitmain S19 Hydro is a factory hydro miner with hashboards designed for liquid cooling from day one. This kit converts a standard air-cooled S19 into a hydro deployment by swapping the heatsinks for water plates. Performance won't match the factory Hydro at peak overclocking, but for normal operation in hot facilities, the gain over air is substantial.

Q: What coolant should I use?
A: Standard distilled water + corrosion inhibitor mixture, or commercial PC water cooling coolant. Avoid tap water (mineral deposits clog channels) and pure water (encourages galvanic corrosion). The anodized aluminum tolerates most water-cooling coolants well.

Q: Will the OEM Bitmain S19 chassis fans need to be removed?
A: Yes — chassis fans are removed after hydro conversion. Pair with the appropriate fan simulator to keep the miner firmware happy (looks for tachometer signal). LYS stocks compatible fan simulators for the S19 family.

Q: Bulk pricing for facility hydro conversions?
A: Yes — email contact@lys-sz.com with your fleet size for tier pricing.
