Noctua NH-U12S TR4-SP3 CPU Cooler

The cooling solution for the processor Noctua NH-U12S TR4-SP3 is a specialized air solution for AMD TR4 and Server SP3 platforms – specifically for large HEDT and server CPUs. Compact in size but massive in cooling potential, it combines the proven U12S tower with optimized mounting for the large TR4/SP3 heat spreader. A 120 mm fan with PWM control, speed from 300 – 1500 RPM, and low noise of 22.4 dBA make the cooler suitable for serious loads without turning the case into a vacuum cleaner. On top of that, it includes Noctua's typical long warranty of 72 months.

What you get

The base is the standard single tower for the NH-U12S series, combined with a 120 x 120 x 25 mm NF-F12 PWM fan, which provides airflow up to 54.97 CFM / 93.4 m³/h. The wide range from 300 to 1500 RPM allows you to keep the system almost silent at idle and sufficiently cooled under full load, especially with the help of the Low-Noise Adaptor (L.N.A.) if you are looking for maximum comfort. The SSO2 bearing is designed for long life and stable operation, which is important for 24/7 systems. The cooling capacity is tied to the official TDP guide from Noctua, so you can check your specific CPU against the manufacturer's recommendations. The package includes a SecuFirm2 TR4/SP3 mounting kit, high-grade thermal paste NT-H1, anti-vibration pads, and additional clips for a second fan if you want a push-pull configuration.

• Specialized support for TR4 and Server SP3 sockets, so the cooler optimally covers the large heat spreader of these CPUs.
• Air cooling type tower, which combines good performance with simpler maintenance compared to water solutions.
• 120 x 120 x 25 mm NF-F12 PWM fan with a range of 300 – 1500 RPM for quiet operation under low load and sufficient airflow under load.
• Maximum airflow up to 54.97 CFM / 93.4 m³/h, providing stable cooling for high-performance TR4/SP3 processors.
• Low noise level of only 22.4 dBA, which is a plus for workstations and servers that are close to you.
• Reliable SSO2 bearing for long life and less vibration compared to basic fans.
• Compact form factor with dimensions of 125 x 71 x 158 mm and weight 870 g, suitable for many mid-tower cases, without extreme load on the motherboard.
• 72 months warranty, reinforcing the idea that this is “install and forget” cooling for long-term use.

Who is this suitable for?

The NH-U12S TR4-SP3 is a logical choice if you are building a TR4 or SP3 workstation, rendering machine, or server where stability and noise are more important than extreme overclocking. It is suitable for systems where you want serious air cooling but do not have space or desire for massive dual-tower or AIO water solutions. If you are aiming for extreme overclock settings on the most power-hungry TR4 chips, you may need a larger cooler, but for most real-world scenarios, this solution is more than sufficient.

The strongest aspect here is the combination of specialized TR4/SP3 mounting, quiet NF-F12 fan, and the long 6-year warranty – you get cooling you can rely on for years without drama.
