Common Applications

The N-RTX3090FE-X-V2 is a full-cover water block dimensioned for the NVIDIA GEFORCE RTX 3090 FOUNDERS EDITION. The cold plate is nickel-electroplated high-purity copper and is topped with a clear PMMA cover, with a matching backplate that does not contact coolant. Coolant routes directly across the GA102 GPU die, the GDDR6X memory packages and the VRM stages in a single pass, which is the relevant configuration for the FE card where rear-mounted memory chips are historically the hardest temperatures to control under sustained load. The high-flow internal pathway supports serial installation alongside other blocks, and a 5V addressable RGB (RBW) strip integrates with mainstream motherboard A-RGB headers. It is intended for builders assembling an open custom loop with a separate pump, reservoir and radiator.

Frequently Asked Questions

Q: Which card is this block compatible with?

A: The NVIDIA GEFORCE RTX 3090 FOUNDERS EDITION only. Aftermarket boards from ASUS, MSI, Gigabyte and others use different PCB layouts and require a model dedicated to that card.

Q: What are the block and backplate materials?

A: Nickel-electroplated high-purity copper cold plate  plus a matching backplate that is not in contact with coolant.

Q: What thread size are the ports?

A: G1/4 inch, compatible with mainstream water-cooling fittings.

Q: Is the RGB 5V or 12V?

A: 5V addressable RGB (A-RGB / RBW), intended for the 3-pin 5V A-RGB header on the motherboard. Do not connect it to a 12V RGB header or the LEDs will be damaged.

Q: What is in the box?

A: One full-coverage GPU water block, one backplate,mounting hardware
