CPU cooler Noctua NH-U12S TR4-SP3, single 120 mm fan, for AMD TR4/SP3 sockets, 158×125×71 mm, 870 g

The Noctua NH-U12S TR4-SP3 is a 120mm single-tower CPU cooler specifically adapted for AMD TR4 and SP3 platforms (Ryzen Threadripper / Epyc). It pairs a slim heatsink with five heatpipes and the NF-F12 PWM 120mm fan to deliver efficient heat dissipation while keeping a compact footprint (125 × 71 × 158 mm). The TR4‑SP3 variant features an enlarged 70 × 56 mm copper contact surface and the SecuFirm2 mounting system designed for large IHS processors, and is supplied with Noctua’s NT-H1 thermal compound and a six-year manufacturer’s warranty.

Advantages

The NH-U12S TR4-SP3 provides strong cooling performance in a 120mm form factor that preserves compatibility with most tower cases and keeps clearance for the top PCIe slot on many motherboards. The custom TR4/SP3 base plate improves heat transfer from large Threadripper/Epyc IHS designs. The NF-F12 Focused Flow fan offers high static pressure and quiet operation, PWM support enables automatic speed control, and a Low-Noise Adaptor reduces maximum RPM for quieter use. Included accessories allow installation of a second fan in push/pull configuration and anti-vibration pads improve acoustics.

Suitable for

• Workstations and desktops using AMD Socket TR4 or SP3 processors (Ryzen Threadripper / Epyc)
• High-performance single-CPU systems where case space above the CPU is limited
• Builds requiring a low-noise cooling solution with PWM fan control

How to use

Apply a small, even amount of the supplied NT-H1 thermal compound to the processor IHS according to the thermal paste instructions. Mount the NH-U12S TR4-SP3 heatsink using the SecuFirm2 TR4/SP3 mounting system: position the cooler on the socket, secure the four spring-loaded screws evenly in a cross pattern until snug. Connect the NF-F12 PWM fan to the motherboard CPU_FAN header for automatic speed control. If desired, fit the optional second NF-F12 fan using the supplied clips and offset pads to create a push/pull configuration.

Recommendations

To maintain optimal acoustic and thermal performance, ensure the cooler is installed with sufficient case airflow and verify clearance with tall RAM modules and the top PCIe slot. Use the Low-Noise Adaptor for quieter operation when full fan speed is not required, and follow Noctua’s torque guidance when tightening the SecuFirm2 screws.
