Common Applications
The N-MS4090VES-X is a full-coverage water block matched to the PCB of the MSI GeForce RTX 4090 Ventus 3X 24G OC. The cold plate is high-purity copper with nickel electroplating to resist oxidation, paired with a PMMA acrylic top and an anodized aluminum backplate that does not contact coolant. Coolant flows directly across the GPU die, GDDR6X memory packages, and VRM phases through a microchannel structure with G1/4 inlet and outlet ports. Top and bottom port pairs support series or parallel routing in multi-card loops, and a pre-installed 5V 3-pin addressable RGB (RBW) strip syncs with mainstream A-RGB headers.
Frequently Asked Questions
Q: Which graphics card is the N-MS4090VES-X compatible with?
