CPU cooler Noctua NH-U12S CPU Cooler DX-4677 LGA4677

This is an air CPU cooler Noctua NH-U12S DX-4677, designed specifically for LGA 4677 socket. This makes it a direct choice if you are working with a platform on this socket and looking for reliable, well-thought-out cooling. With two 120 mm fans and a serious overall profile, the cooler is aimed at higher-end systems where stability under load is more important than flashy RGB. The classic brown design of Noctua suggests a focus on functionality, not on showcase appearance.

What you get is a massive cooler with dimensions 158 x 125 x 97 mm and a weight of 1018 g, which relies on a combination of a quality heatsink and two premium fans NF-A12x25 PWM. The RPM range of 450-2000 RPM gives you broad control – from nearly silent operation in idle to aggressive cooling under serious CPU load. The airflow of 102.1 m3/h is sufficiently high for serious workloads, while the noise level of 22.6 dBA is within comfortable levels for a workstation or enthusiast build. The factory-applied thermal paste NT-H1 and the included SecuFirm2™ mounting kit for LGA4677 make installation significantly easier and cleaner, especially on expensive platforms where you don't want to take risks.

• Specially for LGA 4677 socket, so the mounting and pressure on the CPU are optimized for this platform.
• Air cooling with a large aluminum heatsink, providing reliability and predictable behavior without the complexities of liquid cooling.
• Two included fans 120 x 120 x 25 mm NF-A12x25 PWM for push-pull configuration and better heat dissipation through the heatsink.
• Wide range of 450-2000 RPM, controlled via 4-pin PWM, allowing you to finely tune the fan curve according to noise and temperatures.
• Airflow up to 102.1 m3/h, sufficient for cooling heavily loaded multi-core processors during prolonged renders or compilations.
• Low noise level of 22.6 dBA, aided by a dynamic fluid bearing for long life and smooth operation.
• Included accessories: NA-YC1 4-pin PWM y-cable, pre-applied NT-H1 thermal paste, Torx® T30 tool, and metal logo for the case.
• Compact height of 158 mm, compatible with most mid-tower cases, without sacrificing serious cooling mass.
• 72 months warranty, covering practically the entire lifecycle of a high-end platform.

This cooler is suitable if you are building a serious LGA4677 system – workstation, server chassis, or high-end productivity build, where you care about stable temperatures and silence. If your main priority is RGB show or ultra-compact mini-ITX cases, you are unlikely to find what you are looking for here – this is a tool, not a toy.

Together, the LGA4677 optimized mounting, the two NF-A12x25 PWM fans, and the low noise under serious airflow make this Noctua NH-U12S DX-4677 a very sensible choice for a “set it and forget it” type of cooling for an expensive platform.
