The Bykski B-FRD-GV4090WF-X-V2-360 is a sealed all-in-one liquid cooling kit engineered for Gigabyte RTX 4090 graphics cards. The 360 mm aluminum radiator, 7000 RPM inline pump, flexible tubing, and full-coverage copper water block arrive pre-assembled, pre-filled, and pre-bled.

This kit eliminates custom loop assembly while delivering direct liquid cooling to the GPU chip, memory, and power stages. Mounting the pump inline along the tubing run isolates vibration from the circuit board, reducing operating noise.

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.

The loop is sealed, pre-filled and pre-bled. Do not open it, do not modify the tubing and do not attempt to top it up. Doing so can cause a leak or a pump failure.

Removing the stock cooler from a passively cooled card means it can no longer run on chassis air. Do not power the card without the kit installed and the pump running.

Fitting the kit means removing the stock cooler and exposing the GPU chip. Thermal pads go on the memory and the power stages; thermal paste goes on the GPU chip.

The manufacturer reserves the right to alter the design to expand compatibility, so the delivered item may not match the pictured item exactly.
