Common Applications
The N-RTX3090H-X-V2 is a Version 2 full-cover GPU water block built for the AIC reference PCB used on many non-Founders RTX 3090 and RTX 3080 cards from Palit, Gainward, Galax / KFA2, Leadtek, Maxsun, PNY, Zotac, Inno3D and similar partners. The cold plate is electroplated high-purity copper with a clear acrylic top, contacting the GPU die, GDDR6X memory and VRM stage through thermal pads. A matching backplate is included and ships in the same box. G1/4 ports are present on both the top and bottom edges, so the block accepts serial or parallel routing in multi-GPU loops. Confirm the card's PCB image against the listing before purchase; non-reference designs will not fit.
Frequently Asked Questions
Q: Which graphics cards does the N-RTX3090H-X-V2 fit?
A: RTX 3090 and RTX 3080 cards built on the AIC reference PCB. Listed compatible brands include Palit, Gainward, Galax/KFA2, Leadtek, Maxsun, PNY, Zotac and Inno3D.
Q: Does it fit the Founders Edition or ASUS ROG Strix card?
A: No. The Founders Edition uses a unique V-shaped PCB and the Strix is a custom PCB. Use the dedicated FE or Strix SKUs for those cards.
Q: What heat sources does the block cover?
A: GPU core, GDDR6/6X memory packages and the VRM/MOSFET stage on the front of the PCB.
Q: What is the port size?
A: G1/4 inch. Inlet and outlet are exposed on both the top and bottom edges of the block.
Q: What is in the box?
A: One full-coverage block, one backplate, two G1/4 stop fittings, mounting hardware, thermal pads, thermal grease and a 5V ARGB LED strip.
