Common Applications

The Granzon GBN-ST4080TQ is shaped for ZOTAC's RTX 4080 AMP Extreme AIRO, Trinity and Trinity OC PCBs, and per the bykski.us compatibility list also fits the shared-PCB RTX 4070 Ti AMP Extreme AIRO. A nickel-electroplated high-purity copper cold plate contacts the GPU die, GDDR6X memory and VRM stages, with a black-anodized aluminum backplate framing the build. A 5V addressable RGB (RBW) strip is included. Ports use standard G1/4 inch thread on top and bottom and support parallel or serial multi-block routing.

Frequently Asked Questions

Q: Which ZOTAC cards does this block fit?

A: ZOTAC GAMING RTX 4080, RTX 4080 AMP Extreme AIRO, RTX 4080 Trinity, RTX 4080 Trinity OC and RTX 4070 Ti AMP Extreme AIRO per the bykski.us listing. The 4080 SUPER is not listed - confirm the PCB image first.

Q: Is a backplate included?

A: Yes. A black-anodized aluminum backplate ships with the block.

Q: What RGB does the block use?

A: 5V addressable RGB (RBW). Do not plug into a 12V RGB header - it will destroy the LEDs.

Q: What is the block material?

A: Nickel-electroplated high-purity copper cold plate with a black-anodized aluminum backplate that does not contact coolant.

Q: What fittings does it use?

A: Standard G1/4 inch threaded ports on top and bottom, supporting parallel or serial flow.
