Common Applications
The N-MX4090TB-X is a full-cover water block built for the Maxsun GeForce RTX 4090 Turbo 24G PCB, and the same PCB is shared by the Gainward RTX 4090 Phantom / Phantom GS and the Palit RTX 4090 GameRock / GameRock OC. The cold plate is nickel-electroplated high-purity copper with a high-flow internal geometry, and a single integrated channel cools the AD102 die, GDDR6X memory, and VRM stages. G1/4 ports are exposed at top and bottom for serial or parallel multi-block plumbing. The kit includes a 5V 3-pin A-RGB (RBW) LED strip, a metal backplate, two G1/4 stop fittings, mounting hardware, and thermal grease.
