Common Applications

The N-RTX4070S-SR is a full-cover metal/POM water block matched to the NVIDIA GeForce RTX 4070 Super reference PCB layout. The cold plate is nickel-electroplated high-purity copper combined with stainless steel structural panels and POM detail parts, with a black-anodized aluminum backplate that remains outside the coolant path. The metal-and-POM construction is rated for continuous-duty operation, which suits the workload profile of a 4070 Super used for long rendering sessions, AI inference or extended gaming. The high-flow internal pathway supports running the block in series with other CPU or GPU blocks, so it integrates cleanly into multi-block loops with a shared pump and radiator stack. It is intended for builders assembling a custom open loop and is not an AIO.

Frequently Asked Questions

Q: Which RTX 4070 Super cards is this block for?

A: The NVIDIA RTX 4070 Super reference PCB only. Aftermarket boards with custom PCBs need their own dedicated blocks.

Q: What materials are used in the block and backplate?

A: Nickel-electroplated high-purity copper cold plate, stainless steel panels and POM detail parts on the block; black-anodized aluminum backplate, which does not contact coolant.

Q: Can multiple blocks be plumbed in series?

A: Yes. The high-flow internal design is intended for serial installation alongside other CPU or GPU blocks in the same loop.

Q: What thread size are the ports?

A: G1/4 inch, compatible with mainstream water-cooling fittings.

Q: Is thermal paste and mounting hardware included?

A: Yes. The block ships with a backplate and mounting hardware
