NVIDIA RTX 4090 GPU Liquid Cold Plate – Single-Slot | T-HS202307

Single-slot copper cold plate for the RTX 4090, 19.5 mm total height, for layouts where slot pitch is the limiting factor. 450 W below 65 °C at 48 °C inlet (17 K rise, ≈ 0.038 °C/W) with 20% PGW at 1 LPM / 5 kPa. Choose this version for maximum GPU density; choose the dual-slot for maximum thermal margin.

450 W at < 65 °C surface with 48 °C inlet — 17 K case-to-inlet rise on 20% PG / water (PGW)
5 kPa at 1 LPM — low pressure drop for series and manifold loops
270 × 97 × 19.5 mm — 19.5 mm profile; port position to your chassis layout
TLP-bonded copper, 1 MPa rated — every unit leak-tested before shipment

Engineering overview

Thermal: 17 K case-to-inlet rise at rated load, measured at the contact area with 20% PG / water (PGW). Thermal interface material and mounting pressure set the final junction temperature — we supply the recommended TIM and torque spec with each order.
Hydraulic: 5 kPa at 1 LPM — low pressure drop for series and manifold loops; validated on our flow bench at the rated inlet temperature of 48 °C.
Mechanical: 270 × 97 × 19.5 mm copper plate, 19.5 mm overall height. Mounting pattern matches the target device; custom port orientation and fittings on request.
Construction: TLP – Transient Liquid-Phase Diffusion Bonding — a homogeneous metallurgical joint with no braze filler or flux residue in the coolant path; 1 MPa working pressure, 100% pressure-tested.
Fittings: G1/4 quick-disconnect, barb or custom per drawing; inlet/outlet position to your chassis layout.

Ordering & RFQ

How to order: quote model T-HS202307 with quantity and required fitting type. Samples 1–5 pcs with leak-test report; production quantities after drawing approval.

RFQ checklist: target device and heat load, quantity, coolant type, inlet temperature, target flow rate and available envelope. Send a STEP/PDF of your tray or assembly if port position matters.

FAQ

Can it run on warm water? The rated point is 48 °C inlet with 20% PG / water (PGW). Other inlet temperatures and coolants (pure water, EGW, PGW) are supported — performance is validated per coolant on request.

Can the ports or fittings be customised? Yes — fitting type, thread and inlet/outlet position are set per drawing without changing the qualified core.

What is included? Cold plate, mounting hardware, recommended TIM and torque spec, leak-test report. Datasheet PDF available above; STEP file on request.
