Common Applications

The BS-NVG4090-PA is a full-coverage water block built for the NVIDIA GeForce RTX 4090 Founders Edition reference PCB only. The cold plate uses nickel-electroplated copper paired with a clear acrylic top measuring 198 x 146 x 24 mm, with G1/4 inlet and outlet ports and a 12V 4-pin RGB lighting header. A micro-jet structure routes coolant across the GPU die, GDDR6X memory modules, and VRM stages in a single integrated flow path. The package ships with the block, a metal backplate, two G1/4 plug fittings, a screw set, and a thermal pad kit, and is covered by a 12-month warranty.
