Common Applications

The N-MS4080SGMSL-X is a full-coverage GPU water block designed specifically for the MSI GeForce RTX 4080 SUPER 16G Gaming X Slim PCB layout, replacing the factory air cooler to directly cool the GPU die, GDDR6X memory modules, and VRM power stages in a single block. The cooling base is nickel-electroplated high-purity copper paired with a PMMA acrylic top and a black anodized aluminum backplate that does not touch the coolant. Ports use the standard G1/4 thread, and the block supports series or parallel multi-GPU loops through its high-flow channel design. Lighting is 5V three-pin Addressable RGB (RBW); 12V RGB headers will damage it and must not be connected. The kit ships with installation hardware and thermal paste.

Frequently Asked Questions

Q: Which graphics card does this block fit?

A: The MSI GeForce RTX 4080 SUPER 16G Gaming X Slim only. It follows that exact PCB and is not a universal or reference-PCB block.

Q: What materials are used?

A: Nickel-electroplated high-purity copper cold plate, PMMA acrylic top, and a black anodized aluminum backplate. Only copper contacts the coolant.

Q: What RGB header does it use?

A: 5V three-pin Addressable RGB (RBW). It is not compatible with 12V four-pin RGB headers; mixing them will damage the LEDs.

Q: Does it support multi-GPU loops?

A: Yes. The high-flow internal layout allows blocks to be plumbed in series or parallel for dual- or quad-card configurations using G1/4 fittings.

Q: What is in the box?

A: The block with backplate, mounting hardware, and thermal paste. Printed instructions are not included; installation is shown in the manufacturer gallery.
