Engineering overview

Thermal: typical cold-plate thermal resistance 0.036–0.055 °C/W @ 25 °C (case-to-coolant, 25 °C ambient). Rated TDP per model is listed in the table; final CPU temperature depends on chassis airflow and inlet air temperature.
Hydraulic: integrated 40 × 40 mm, PWM 3200 rpm pump, 4.5 L/min max flow and 1.5 m max head; sealed loop, no user fill or maintenance.
Mechanical: 1U rack server radiator with 8 × 40 mm fans; hose custom length; platform-specific retention kit for each socket.
Construction: full-copper skived micro-channel cold plate, brazed; high-density brazed aluminium radiator with black powder coat; every unit pressure- and leak-tested before shipment.
Control: 4-pin PWM fans and PWM pump — speed follows the board’s CPU-temperature fan curve.

Ordering & RFQ

How to order: quote the model number from the table with quantity and target chassis. Samples 1–5 pcs with leak-test report; production quantities after drawing approval.

RFQ checklist: CPU/GPU model and TDP, chassis height and available radiator bay, fan-header power budget, hose routing and expected quantity. Send a STEP/PDF of your chassis if radiator position matters.

FAQ

Does it need a CDU or facility water? No — the loop is sealed and factory-filled; the radiator rejects heat to chassis airflow like an air cooler.

Can the hose length or radiator position be changed? Yes — hose length and radiator orientation are set per chassis drawing; the qualified pump-block stays unchanged.

What is included? Cold-plate/pump block, radiator with fans, hose set, mounting kit and thermal paste; leak-test report on request.
