Common Applications

The N-RTX5090AI-120-SR is a dedicated full-cover water block for the NVIDIA GeForce RTX 5090 AI 32G accelerator card. The cold plate is nickel-electroplated high-purity copper combined with stainless steel structural panels and POM detail parts, paired with a black-anodized aluminum backplate that remains outside the coolant path. This metal construction is rated for continuous-duty operation, which matches the workload profile of an RTX 5090 AI deployment running long training or inference sessions where the stock cooler is the dominant thermal limit. The high-flow internal pathway supports running the block in series with additional CPU or GPU blocks, so it integrates into multi-card AI workstations and rack-style server builds sharing an external pump and radiator stack. 

Frequently Asked Questions

Q: Which graphics card is this block designed for?

A: The NVIDIA GeForce RTX 5090 AI 32G specifically. It is not interchangeable with consumer RTX 5090 gaming variants, which use different PCB layouts and require their own dedicated blocks.

Q: What are the block and backplate materials?

A: Nickel-electroplated high-purity copper, stainless steel ; black-anodized aluminum on the backplate, which does not contact coolant.

Q: Is this block suitable for continuous AI workloads?

A: Yes. The metal construction is rated for continuous-duty operation, the relevant profile for sustained AI training and inference.

Q: Can it be plumbed in series with other blocks?

A: Yes. The high-flow internal design is intended to support series installation alongside other CPU or GPU blocks in a shared loop.

Q: What is in the box?

A: One full-cover water block, one backplate, mounting hardware. Backed by a 1-year warranty against defects.
