The TR4-SP3 version is a tailored custom model for AMDs sTRX4/TR4/SP3 platform (Ryzen Threadripper / Epyc) and features a larger contact surface as well as the latest SecuFirm2 mounting system for socket sTRX4/TR4/SP3. Topped off with two of the renowned quiet NF-A9 PWM 92mm fans in a push/pull dual fan configuration, Noctuas proven NT-H1 thermal compound and a full 6-year manufacturers warranty, the NH-U9 TR4-SP3 forms a highly compact, premium-quality solution that combines outstanding performance, superb acoustics and excellent compatibility for space-restricted sTRX4/TR4/SP3 systems.
Please note
that the NH-U9 TR4-SP3 is a dedicated version for the AMD sTRX4/TR4/SP3 socket. Due to its customised larger base, it cannot be used on any other sockets and is incompatible with Noctuas standard mounting kits.

The Noctua NH-U9 TR4-SP3 is a dual-fan, 92mm CPU air cooler for AMD sWRX8, sTRX4, TR4, and SP3 systems, suited to Threadripper and EPYC builds where a 125mm cooler height and 4U-compliant design help with case and PCIe clearance.
Recommended For
- Builders fitting an AMD TR4/SP3 Threadripper or EPYC workstation into a 4U rackmount or other height-limited case; the 125 mm-tall cooler is designed for space-restricted systems.
- Threadripper builders who need to preserve clearance around the top PCIe slot—for example, in a multi-GPU workstation—without using a larger tower cooler.
- Workstation or server users who want air cooling for compatible Threadripper or EPYC systems and prefer the dual-fan cooler’s lower-noise approach over typical server cooling solutions.
- Linux workstation users running compatible Threadripper CPUs for mixed workloads such as parallel compilation and single-threaded tasks, who want a compact air cooler rather than liquid cooling.
Real-World Use Scenarios
- In a 4U Threadripper or EPYC rack workstation, the NH-U9 TR4-SP3 can provide air cooling where a taller tower cooler may not fit; check the exact case clearance before installation.
- When building a Threadripper system in a compact case, its short cooler profile can make air cooling practical; confirm the case’s cooler-height limit and nearby component clearance first.
- For a Threadripper build where the top PCIe x16 slot needs to remain accessible, the cooler’s narrow layout is designed to avoid overhanging that slot, helping with motherboard expansion-card planning.
- For CPU-heavy workstation tasks such as parallel code compilation or OpenMP workloads, testing on a Threadripper 1950X found the cooler handled those loads without reported thermal issues in the review system; results can vary with the CPU, case airflow, and workload.
- For a server or workstation used near people, its dual-fan setup can offer a quieter air-cooling option than some high-speed server coolers, though fan noise may rise under heavy loads.
