Common Applications

The GBN-RTX3090TIFE is a full-armor water block built only for the Nvidia RTX 3090 Ti Founders Edition PCB. The cold plate is high-purity copper electroplated with nickel to resist oxidation, and a 0.3mm jet microchannel sits directly above the GA102 die with a fin array roughly three times the area of the core itself to increase coolant contact. Front and back aluminum armor wrap the block and PCB without touching the coolant, adding rigidity to the long Founders Edition card while leaving the channel face visible through the acrylic top. The block cools the GPU core, GDDR6X memory, and VRM stages in a single pass, uses G1/4 threaded ports, and includes a hollow-bottom section that lets residual board heat escape rather than being trapped against the backplate. Top and bottom ports support parallel or serial multi-block plumbing.

Frequently Asked Questions

Q: Which RTX 3090 Ti variant does this block fit?

A: Nvidia RTX 3090 Ti Founders Edition only. AIB variants such as ROG Strix, Aorus, Suprim, or Gaming Trio use different PCBs and are not compatible.

Q: What is the cold plate material?

A: High-purity copper, electroplated with nickel to prevent oxidation. The front and back armor pieces are anodized aluminum and do not contact the coolant.

Q: What size are the inlet and outlet ports?

A: Standard G1/4 thread. Top and bottom port positions allow parallel or serial layout in multi-GPU loops.

Q: What components does the block cool?

A: GPU core, GDDR6X memory modules, and VRM stages, plus the inductors covered by the supplied thermal pads.

Q: Does the block include RGB lighting?

A: Some channel runs of this SKU ship without integrated lighting and others ship with 5V A-RGB. Check the specific listing variant; the wetted core, fittings, and armor are identical.
