Common Applications
The N-IG4070ZF-X is a full-cover water block matched to the PCB of the Colorful iGame GeForce RTX 4070 Battle-AX and Ultra W OC variants. The cold plate is high-purity copper with nickel electroplating to prevent oxidation, paired with a PMMA acrylic cover and a black anodized aluminum backplate that stays out of the coolant path. A 0.5mm micro-channel structure sits over the GPU die, while large-flow channels carry coolant across the GDDR6X memory and VRM stages so the entire card runs from a single block. Inlet and outlet ports are G1/4 inch on both top and side, allowing serial or parallel loop routing. A pre-installed 5V 3-pin ARGB strip lights the cover, and the kit ships with backplate, stop fittings, screwdriver, lighting sync cable and thermal pads.
