Common Applications

The N-GY4070STXMINI-X is sized to the compact PCB of the Gainward GeForce RTX 4070 Super Snow Mini and is not interchangeable with full-length 4070 Super designs. A nickel-electroplated high-purity copper cold plate makes direct contact with the AD104 die, with internal microfins fed by a high-flow channel that also pulls heat from GDDR6X memory and VRMs via pre-cut thermal pads. A clear acrylic (PMMA) top lets the pre-installed 5V A-RGB strip illuminate the channel pattern. G1/4 ports are mirrored on the top and bottom of the block to allow series or parallel multi-card plumbing without additional adapters.

Frequently Asked Questions

Q: Is the N-GY4070STXMINI-X only for the Snow Mini variant?

A: Yes. It is dimensioned for the Gainward RTX 4070 Super Snow Mini PCB only. Standard-length Gainward 4070 Super cards use a different PCB and need a different block.

Q: What materials are used?

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

Q: Is the RGB 5V or 12V?

A: 5V addressable A-RGB (RBW). It is not compatible with 12V RGB headers; mixing voltages will damage the strip and the header.

Q: What is in the box?

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

Q: What fitting size does the block use?

A: Standard G1/4 thread on every port. Any G1/4 compression or barb fitting will fit.
