Frequently asked questions

What should I do if the pre‑applied thermal paste is missing?

Apply a thin layer of thermal paste yourself before attaching the cooler to the CPU.

Can the NH‑U12S DX‑4189 be used with LGA4189‑5 sockets?

The same mounting hardware can be used, but a different CPU carrier frame is required; contact Noctua support for the appropriate frame.

How should I handle the cooler during transport?

Handle the cooler gently, avoid excessive pressure, and keep it dry; Noctua is not liable for damage caused by transport stress.
