Compatibility Target

This water block fits NVIDIA GeForce RTX 3080 and 3090 graphics cards built to the reference design layout. It is intended for builders assembling a custom liquid-cooling loop for those specific models. Buyers with non-reference board layouts or other GPU generations cannot use this block.

Critical Specification

The mounting pattern and cold-plate machining match the reference PCB exactly, so the block only aligns with reference-design cards. Nickel-plated copper covers the GPU and VRM zones, while an acrylic top integrates a D-RGB LED strip. Four G1/4-inch threads accept standard fittings.

Sustained-Load Behaviour

Under continuous load the copper base spreads heat from the GPU and VRMs into the flowing coolant, keeping temperatures stable during long render or compute sessions. The aluminium backplate adds structural rigidity and helps draw residual heat from the rear of the PCB. The D-RGB lighting remains constant regardless of thermal load.

Questions about this item

How does the nickel-plated copper base contact the GPU and VRM on an RTX 3080 or 3090 Reference card?

The base plate is carved to cover the full length of the card, maximising contact over the GPU die and VRM area for heat transfer.

What fitting thread does the block use and how many ports are provided?

Four G1/4" threaded ports are built into the block for standard hard-tube or soft-tube fittings.

Does the package include a backplate and mounting hardware for the Reference PCB?

Yes, a black aluminium backplate, thermal pads and all mounting screws are supplied in the box.
