Bykski Durable All Metal GPU Water Block and Backplate For NVIDIA GeForce RTX 4080 SUPER 32GB (N-RTX4080S-SR) - Continuous Usage

The Bykski N-RTX4080S-SR is a continuous-duty liquid cooling block for NVIDIA GeForce RTX 4080 SUPER 32GB graphics cards. It covers the GPU chip, memory, and power stages in one pass. Removing the stock heatsink transfers the card's thermal load directly to the liquid cooling loop.

Machined from T2 copper with 0.001-0.002 mm electroless nickel plating, the 9.5 mm cold plate features a 0.35 mm base over the GPU core and 56 micro-channels that are 0.3 mm wide. The nickel-plated copper top and EPDM seal are rated for up to 4 bar working pressure, and an aluminum backplate supports the circuit board.

Warnings

Warranty is repair or replacement. All returns are accepted within 30 days, no questions asked. An installed or used item comes back at a higher restocking fee.

Installation removes the card's stock heatsink, after which it can no longer be cooled by chassis air. Never power the card without the loop installed and the pump running. Thermal pads go where the block has corresponding raised contact points; the die itself uses thermal paste.
