Antminer S19 90T Water Cooling Board - Hydro Cooling Solution

Antminer S19 90T Water Cooling Board Kit | Aluminum Hydro Plate Upgrade for BTC Mining Efficiency

The Antminer S19 90T water cooling board kit is a complete hydro retrofit for the air-cooled S19 90T miner. Replaces the original fan-cooled heatsinks with aluminum alloy water-cooling plates: 2 boards per hashboard, 3 hashboards per miner = 6 plates per complete kit. Couples the miner to an external water loop for sustained high-load mining with controlled junction temperatures.

Hydro upgrade is the right move when the S19 90T runs in a hot environment, when noise reduction matters (silencer + hydro combo), or when adding the miner to an existing immersion / hydro farm infrastructure. Aluminum plates are CNC-machined for full contact across the ASIC chip array — uneven contact is the main failure mode for retrofit kits, and this kit's manufacturing tolerances target full thermal coupling.

What's in the Kit

• 6 × aluminum alloy water cooling plates (2 per hashboard, 3 hashboards per miner)
• 2 × multi-function liquid shunts — manifold for 1 to 6 ASIC miners off a single loop
• 2 metres × silicone water pipe — flexible secondary tubing
• 2 metres × main water pipe — primary supply / return
• Clamps for secure pipe-to-fitting installation

FAQ — S19 90T Water Cooling Kit

Q: Does this kit include the pump and radiator?
A: No — this is the cold-plate + manifold + tubing kit only. Pump, reservoir, and radiator come from a separate water-cooling kit (e.g. the Lian Li 12KW Hydro ASIC kit listed below) sized to your fleet's total heat load. One pump can feed multiple miners through the included shunts.

Q: Installation difficulty?
A: Moderate. Open the miner, remove the original heatsinks (preserve the thermal interface), install the cold plates with fresh thermal paste, route the tubing through the chassis, install the shunts, connect to the external loop. Plan on a full bench session per miner the first time.

Q: Will the S19 90T's stock fans still run after the swap?
A: Depends on the install — most operators remove the fans entirely (silencer enclosure + hydro = silent operation) and use a fan speed simulator on the control board to keep the firmware happy. See the related Antminer fan simulator products.

Q: Bulk pricing for hydro farm fleet retrofits?
A: Yes — email contact@lys-sz.com for case-quantity S19 90T hydro kit pricing and matched pump / radiator solutions.
