Common Applications
The N-YT4080-X is a full-coverage block designed exclusively for the Yeston GeForce RTX 4080 16G D6X Sakura Sugar PCB. The cold plate is machined from nickel-electroplated high-purity copper with 0.5mm micro-channels over the GPU die and a high-flow MOS channel feeding the VRM area, so the GPU, GDDR6X memory and VRM are cooled by the same coolant pass. A PMMA top routes flow between two G1/4 ports, and a black anodized aluminum backplate stiffens the card and isolates rear-side components. Lighting is delivered by a pre-installed 5V 3-pin addressable RGB strip with an included sync cable for motherboard A-RGB headers.
Frequently Asked Questions
Q: Which graphics card does the N-YT4080-X fit?
A: The Yeston GeForce RTX 4080 16G D6X Sakura Sugar only. Other RTX 4080 boards use different PCB layouts and are not supported.
Q: What materials are used in the block and backplate?
A: Nickel-electroplated high-purity copper cold plate, PMMA acrylic top with G1/4 threads, and a black anodized aluminum backplate that does not contact the coolant.
Q: What is in the box?
A: 1x full-cover water block, 1x backplate, 2x stop fittings, 1x installation screwdriver, 1x A-RGB sync cable, and a Bykski thermal pad set.
Q: Is the A-RGB strip 5V or 12V?
A: 5V 3-pin addressable RGB (RBW). Do not connect it to a 12V 4-pin RGB header; mixing 5V and 12V lighting will damage the strip.
Q: Can the block run with an aluminum radiator?
A: No. The cold plate is copper, so mixing it with aluminum radiators or fittings will cause galvanic corrosion. Use copper or brass loop components only.
