Common Applications

The A-RX7900XT-X targets the AMD reference Radeon RX 7900 XT PCB. The cold plate is nickel-electroplated high-purity copper sealed under a PMMA top, and the load is taken by a black anodized aluminum backplate that never contacts coolant. The block cools GPU die, GDDR6 memory and the VRM stage in a single pass, with G1/4 inlet and outlet on both the top and bottom edges so the block can be configured for serial or parallel routing in multi-block loops. A 5V addressable RGB (RBW) strip is pre-installed under the acrylic for sync with motherboard A-RGB headers.

Frequently Asked Questions

Q: Will this fit AIB partner cards?

A: No. The A-RX7900XT-X is cut for the AMD reference RX 7900 XT PCB only. Sapphire Nitro+, ASUS TUF, XFX Merc and other partner cards use their own PCB layouts and need dedicated blocks.

Q: What materials touch the coolant?

A: Only the nickel-electroplated high-purity copper cold plate and the PMMA top. The aluminum backplate is dry.

Q: What thread size are the ports?

A: G1/4 inch, with ports on both top and bottom edges for serial or parallel multi-GPU routing.

Q: Is the RGB header 5V addressable?

A: Yes, 5V 3-pin A-RGB (RBW). Do not connect to a 12V 4-pin RGB header.

Q: What is in the box?

A: One full-cover GPU block, one aluminum backplate, two G1/4 blanking plugs, mounting hardware, thermal pads, manual, and a 5V RBW LED strip.
