CPU Cooler Noctua NH-U14S TR4-SP3 — 140 mm fan, Socket TR4/SP3, 165 mm height, 1.03 kg

The Noctua NH-U14S TR4-SP3 is a 140mm single-tower CPU cooler specially customised for AMD TR4/SP3 platforms (Ryzen Threadripper / EPYC). It extends the award-winning NH-U series with a larger copper contact surface and the SecuFirm2 mounting system for secure installation on TR4/SP3 sockets. Equipped with the quiet NF-A15 140mm PWM fan, proven NT-H1 thermal compound and a six-year manufacturer’s warranty, the NH-U14S TR4-SP3 delivers high cooling performance and low noise for enthusiast-class systems.

Advantages

The cooler offers optimized heat transfer for large integrated heat-spreaders thanks to its enlarged 70 x 56 mm copper base. With six heatpipes, a large fin surface area and the NF-A15 140mm fan, it provides strong thermal performance for high-end TR4/SP3 CPUs while keeping acoustic levels low. The SecuFirm2 mounting system ensures simple, secure installation, and offset mounting options improve compatibility with top PCIe slots. The package also includes anti-vibration pads, fan clips for an optional second fan and the NT-H1 thermal paste.

Key specifications

• Compatibility: AMD TR4 / SP3 (Ryzen Threadripper / EPYC)
• Contact surface: 70 x 56 mm copper base
• Fan: NF-A15 140mm PWM (includes Low-Noise Adaptor, 1500 → 1200 rpm)
• Heatpipes: 6 heatpipes
• Fin surface area: > 6000 cm²
• Mounting system: SecuFirm2 for TR4/SP3 with 3 mm / 6 mm offset options
• Accessories: NT-H1 thermal compound, anti-vibration pads, fan clips for second fan
• Warranty: 6-year manufacturer’s warranty

How to use

Place the heatsink onto the processor IHS of the TR4/SP3 socket, apply the supplied NT-H1 thermal compound according to the instructions, then secure the cooler by tightening the four spring-loaded screws of the SecuFirm2 mounting system. Connect the NF-A15 PWM fan to a motherboard CPU fan header for automatic speed control; use the Low-Noise Adaptor if lower maximum RPM is desired. To increase cooling, install an optional second NF-A15 in a push/pull configuration using the included fan clips and anti-vibration pads, offsetting the rear fan by 5 mm if acoustic improvement is needed.

Recommendations

Verify case clearance and top PCIe slot position before installation. Use the provided offset mounting options if the cooler interferes with the top PCIe slot. Replace thermal compound if re-installing the cooler after removal and follow motherboard manual guidance for fan headers and PWM control.
