Common Applications

The N-ST4080SPGF-X is engineered around the PCB of the Zotac GeForce RTX 4080 SUPER 16GB PGF OC and is not interchangeable with the Trinity, AMP or any other 4080 Super variant. A nickel-electroplated high-purity copper cold plate makes direct contact with the AD103 die, with internal microfins drawing heat from the GDDR6X memory and VRMs through pre-cut thermal pads. A clear acrylic (PMMA) top exposes the channel pattern and houses the pre-installed 5V A-RGB strip. G1/4 inlet and outlet ports are mirrored top and bottom, so two blocks can be plumbed in series or parallel without adapters.

Frequently Asked Questions

Q: Which Zotac 4080 Super model is supported?

A: Only the Zotac GeForce RTX 4080 SUPER 16GB PGF OC PCB. Compare against the reference PCB image on the manufacturer page before ordering - Trinity and AMP variants use different PCBs.

Q: What materials are used?

A: Nickel-electroplated high-purity copper cold plate, clear acrylic (PMMA) top and a metal backplate. Only nickel-plated copper contacts coolant.

Q: Is the lighting 5V A-RGB or 12V RGB?

A: 5V addressable A-RGB (RBW). Connecting to a 12V RGB header will destroy the LEDs.

Q: What is in the box?

A: GPU water block, metal backplate, two stop fittings, mounting hardware, thermal grease, pre-cut thermal pads, and a pre-installed 5V A-RGB strip.

Q: Can two N-ST4080SPGF-X blocks share one loop?

A: Yes. Top and bottom G1/4 ports let two blocks run in series or parallel for SLI-style dual-GPU loops.
