Noctua NH-U9S Review & Specifications

The Noctua NH-U9S by Noctua is a Air CPU cooler designed for compatibility with AM5, AM4, LGA 1700, LGA 1851, LGA 1954, LGA 1156, LGA 1155, LGA 1150, LGA 1151, LGA 1200 sockets.

This air cooler features a heatsink with a CPU contact base made of Copper, which is typically nickel-plated to prevent oxidation and ensure long-term durability while maintaining the superior thermal conductivity of the underlying copper. While some coolers use a solid nickel-plated copper base for maximum surface area and durability, others, usally lower to midrange coolers, utilize direct-touch heatpipes to transfer heat immediately from the CPU into the cooling system. It includes 1 fan(s), each sized at 92 mm. These fan(s) can reach up to 2000.0 RPM and operate at a noise level of 22.8 dBA, delivering a combined airflow of 46.4 CFM. The total height of the cooler is 125 mm . Please ensure your PC case supports this cooler’s height. You can verify compatibility using our PC Builder, which filters compatible cases based on CPU cooler dimensions. This cooler does not include RGB lighting, focusing instead on performance, reliability, and low acoustic output. The cooler is backed by a 6-year warranty, providing long-term reliability and manufacturer support.

Performance

Noctua NH-U9S is a mid-range performance air CPU cooler designed for CPUs with TDPs up to 150 W, reaching a relative cooling performance score of 61.00%. Ideal for entry-level to mid-range gaming systems and lower-power workstation builds, it offers excellent reliability thanks to its simple construction. Compared to liquid cooling systems, air coolers in this class are strongly recommended due to the absence of pumps, fluid, or risk of leaks. At this TDP level, air coolers generally outperform similarly priced liquid coolers in both reliability and long-term value.

Cost-Effectiveness

The Noctua NH-U9S delivers a well-balanced performance-to-price ratio of 38.4%, making it a solid mid-range option for users who value both affordability and reliable cooling.
