Noctua NH-U14S TR4-SP3 CPU Cooler

The cooling solution for the processor Noctua NH-U14S TR4-SP3 is a serious air cooler aimed at HEDT / server platforms with TR4 and Server SP3 sockets. This is a massive cooler with a height of 165 mm and a weight of 1030 g, designed to handle heavy loads under long load conditions. The combination of a large heatsink and a 140 mm fan provides strong airflow at relatively low noise levels. The manufacturer refers to its own TDP guide, which suggests a focus on actual cooling rather than just marketing figures.

What you get

The base of this model is the large 140 mm fan NF-A15 PWM with dimensions 150 x 140 x 25 mm, which spins in the range of 300 to 1500 RPM. At maximum speed, it provides airflow up to 82.52 CFM (140.2 m³/h), which is perfectly in tune with the needs of multi-core TR4 / SP3 CPUs during serious rendering, virtualization, or other heavy tasks. At this level of airflow, the noise is up to 24.6 dBA, so your machine can remain relatively quiet even under load. The 4-pin PWM connector provides precise control through the motherboard – you can set aggressive cooling curves or prioritize silence. The massive heatsink plus the quality paste NT-H1, included in the package, help you maximize the thermal capacity of the cooler according to Noctua's TDP guide.

• Air cooling focused on HEDT platforms, compatible with TR4 and Server SP3 sockets for Ryzen Threadripper and server CPUs.
• Large 140 mm fan with dimensions 150 x 140 x 25 mm, optimized for a balance between pressure and airflow through a dense heatsink.
• Wide RPM range from 300 – 1500 RPM, allowing for both very quiet idle and aggressive cooling under load.
• Maximum airflow up to 82.52 CFM / 140.2 m³/h, suitable for cooling multi-core CPUs under prolonged loads.
• Low noise level up to 24.6 dBA, so even at higher RPMs, the system remains comfortable to work near.
• SSO2 bearing on the fan for long life and stable operation under 24/7 load – important for workstations and servers.
• Rich package: NF-A15 PWM fan, Low-Noise Adaptor, thermal paste NT-H1, SecuFirm2 mounting kit, anti-vibration pads, clips for a second fan, and a metal logo for the case.
• Compact for its class design with dimensions 150 x 78 x 165 mm, allowing compatibility with most wider cases for HEDT configurations.
• Long warranty of 72 months, which is a strong plus if your machine runs serious hours every day.

Who it is suitable for

This cooler is for you if you are building a workstation or server configuration on TR4 / SP3 and want stable air cooling without switching to AIO. It is suitable for rendering, compiling, virtualization, and any tasks that keep the CPU under constant load. It is not suitable if your case is narrow or if you are looking for something low-profile for a compact chassis.

The combination of a massive heatsink, quiet 140 mm fan, and well-thought-out mounting kit makes the Noctua NH-U14S TR4-SP3 a very solid solution for serious TR4 / SP3 systems, where stable temperatures and long life are more important than RGB and decoration.
