Noctua NH-U9 TR4-SP3, 2x92 mm CPU Cooler, Brown

The Noctua NH-U9 TR4-SP3 is a dedicated compact CPU cooler engineered specifically for high-performance AMD Threadripper and Epyc processors. It ensures full coverage and direct contact with the large heat spreaders found on TR4, sTRX4, SP3, and sWRX8 sockets. This design facilitates efficient thermal transfer required by these high core count architectures in restrictive computing environments.

Heat dissipation relies on a robust construction featuring a nickel-plated copper base and six 6 mm heat pipes leading into the aluminum fin array. Measuring 125 mm high, 95 mm wide, and 120 mm deep, the unit maintains a profile suitable for use in 4U server racks or space-constrained workstation chassis where standard tower coolers cannot fit. The physical dimensions prioritize maximum compatibility without compromising core cooling capacity.

A thermal load is managed by a dual-fan push/pull arrangement utilizing two 92 mm NF-A9 PWM fans. These units operate up to 2000 RPM and deliver a maximum static pressure of 2.28 mmH₂O, balancing airflow performance with controlled acoustics. The fans use SSO2 bearings rated for an MTBF of 150,000 hours, ensuring long-term operational reliability in server and professional workstation applications.
