Common Applications

Built for the ASUS ROG Strix and TUF Gaming RTX 4080 PCB family, the Granzon GBN-AS4080STRIX delivers full-cover cooling in a single armored package. Its nickel-electroplated high-purity copper cold plate bonds to the AD103 die, GDDR6X memory pads, and VRM phases in one pass, while a black-anodized aluminum frontplate and matching backplate stiffen the long PCB without ever contacting coolant. G1/4 top and bottom ports allow parallel or serial routing in multi-block loops. The kit ships with mounting hardware and thermal grease; thermal pads sit on raised contact points where the block meets memory and VRM.

Frequently Asked Questions

Q: Which ASUS RTX 4080 cards are supported?

A: ASUS ROG Strix GeForce RTX 4080 and ASUS TUF Gaming GeForce RTX 4080. The 4080 SUPER variants share a similar PCB but compatibility is not manufacturer-confirmed - check the PCB image first.

Q: Does the kit include a backplate?

A: Yes - both a frontplate armor and a backplate armor, both in black-anodized aluminum that never contacts coolant.

Q: What fittings and ports are used?

A: G1/4 inch threaded ports on top and bottom, configurable for parallel or serial multi-block loops.

Q: What is in the box?

A: One full-cover GPU water block, one frontplate armor, one backplate armor, two stop fittings, mounting hardware, and thermal grease.

Q: Will my card's stock backplate fit on top of this block?

A: Stock backplates are not guaranteed to refit because mounting hole positions vary between cards - install the included Granzon backplate instead.
