The NH-U14S TR5-SP6 is a 140mm size premium quality quiet CPU cooler for workstations and servers based on AMD Threadripper and Epyc processors that utilise sTR5/SP6 sockets. Built on the proven basis of the renowned TR4-SP3 model with its large heatsink and full-cover contact surface, the TR5-SP6 revision employs two of Noctua’s award-winning, PWM controlled NF-A15 140mm fans in order to achieve maximum performance and superb acoustics. Topped off with the pre-applied NT-H2 thermal compound as well as the professional SecuFirm2™ mounting system for sTR5/SP6 that has been updated to meet the platform’s increased pressure specifications, the NH-U14S TR5-SP6 forms a complete premium quality package for quietly cooling sTR5-based Threadripper workstations and SP6-based Epyc servers.
• Key Features
Massive 70x56mm Contact Surface: More than double the size of standard desktop coolers, the nickel-plated copper base is tailored to perfectly fit the enormous IHS of AMD Threadripper 7000 and EPYC 8004 series processors.
Dual NF-A15 140mm Fans: Achieve unrivaled cooling efficiency. The push/pull configuration uses two of Noctua's award-winning SSO2 bearing fans to drive massive airflow (140.2 m³/h) through the heatsink at incredibly low noise levels.
Pre-Applied NT-H2 Thermal Paste: Save precious time during system integration. Noctua’s pro-grade NT-H2 thermal compound comes pre-applied to the heatsink base in a highly optimized honeycomb pattern, ensuring flawless, mess-free thermal transfer.
Offset SecuFirm2™ Mounting: The professional mounting system allows you to offset the cooler by 3mm or 6mm. This brilliant engineering trick helps increase clearance for the top PCIe slot or rear I/O panel on crowded workstation motherboards.
Whisper-Quiet PWM Control: Under idle loads, the fans spin down to near-silent levels. Even at a maximum speed of 1500 RPM, the acoustic profile never exceeds a barely audible 24.6 dB(A), making it ideal for noise-sensitive audio/video production studios.
• Performance / Technology
The NH-U14S TR5-SP6 utilizes 6 heavy-duty copper heatpipes bonded to densely packed aluminum cooling fins with soldered joints. This rugged construction prevents thermal degradation over years of thermal cycling, delivering absolute reliability for servers that cannot afford downtime.
• Compatibility / Use Cases
Warning: This is a dedicated cooler. It is strictly compatible with AMD sTR5 (Threadripper / Threadripper PRO 7000) and SP6 (EPYC 8004) sockets. It will not fit standard desktop AM5 or Intel LGA1700 sockets. It is the ultimate air-cooling solution for 3D animation studios, AI engineering labs, and high-frequency trading servers.
• Why This Product Stands Out
Liquid cooling in servers introduces a catastrophic point of failure if a pump dies or a tube leaks. The Noctua NH-U14S TR5-SP6 stands out by offering thermal performance that rivals 360mm AIO liquid coolers, but with the bulletproof, zero-maintenance reliability of an air cooler—backed by Noctua's legendary 1-year manufacturer warranty.
