Bykski GPU Water Block and Backplate For AMD Radeon RX 7900 XTX (A-RX7900XTX-X)

The Bykski A-RX7900XTX-X full-coverage water block cools the GPU chip, video memory, and power stages. The nickel-plated copper plate routes coolant across core heat zones beneath a clear acrylic top.

Replacing the stock air cooler drops operating temperatures under load and removes fan noise from the chassis. The aluminum backplate braces the circuit board, and integrated 5V addressable RGB lighting connects to standard motherboard headers.

Warnings

Warranty is repair or replacement. Returns are accepted within 30 days, no questions asked. A restocking fee applies to every return, with a higher fee for items that have been installed or used.

The top is acrylic. Tighten mounting screws evenly and finger tight - over-tightening cracks acrylic, and a cracked top is not covered. Installation removes the card's stock cooler, so 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.

No instructions are included, the installation illustration is in the gallery images. The manufacturer may modify the design, so the delivered product may differ from the images. Qualified users must install it themselves. The manufacturer isn't liable for damage caused by misuse, improper installation, noncompliant operation, or incompatible hardware or fluids. Use constitutes acceptance of these risks.
