The Bykski N-GV4090WF-X-V2 is a full-coverage GPU water block with backplate for GIGABYTE GeForce RTX 4090 WindForce V2 24G and TURBO 24G graphics cards. It cools the GPU chip, memory, and power stages in one pass, routing heat directly into the liquid loop.
Built for continuous duty, the block features a T2 copper cold plate with a 0.35 mm base thickness and 0.001-0.002 mm electroless nickel plating. The POM terminal provides parallel side ports, while the aluminum backplate braces the circuit board.

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.
