Noctua NH-D9 TR5-SP6 4U Review & Specifications

The Noctua NH-D9 TR5-SP6 4U by Noctua is a Air CPU cooler designed for compatibility with sTR5, SP6 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 2 fan(s), each sized at 92 mm. These fan(s) can reach up to 2500.0 RPM and operate at a noise level of 30.6 dBA, delivering a combined airflow of 56.7 CFM. The total height of the cooler is 134 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-D9 TR5-SP6 4U is a mid-range performance air CPU cooler designed for CPUs with TDPs up to 150 W, reaching a relative cooling performance score of 67.00%. 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 performance-per-price ratio of Noctua NH-D9 TR5-SP6 4U is 22.7%, which places it in the lower tier of value for air coolers. This air cooler does not provide strong performance, and with a low value score, it is generally not a recommended option unless aesthetics or specific design features justify the price.
