120mm size for excellent performance and compatibility

With five heatpipes and the powerful NF-F12 120mm fan, the NH-U12S achieves outstanding cooling performance while maintaining excellent compatibility: At 158mm height and 125mm width, it is short enough to fit most modern tower cases and stays clear of the top PCIe slot on most motherboards.

SecuFirm2 mounting system for sTRX4/TR4/SP3

Noctua’s SecuFirm2 mounting systems have become synonymous with quality, safety and ease of use. The TR4-SP3 variant has been completely custom-designed for the new socket and is particularly easy to install: Put on the heatsink, fix the four spring-loaded screws and you’re done!

Offset mounting options for better PCIe clearance

In order to assure optimal compatibility with SLI and CrossFire multi-GPU setups, the SecuFirm2 mounting for sTRX4/sWRX8/TR4/SP3 makes it possible to offset the cooler by 3 or 6mm towards the upper edge of the motherboard, thereby increasing clearance of the top PCIe slot.

Tailored custom version for sTRX4/TR4/SP3 (Ryzen Threadripper / Epyc)

Please note that the NH-U12S TR4-SP3 is a dedicated version for the AMD sTRX4/sWRX8/TR4/SP3 socket. Due to its customised larger base, it cannot be used on any other sockets and is incompatible with Noctua’s standard mounting kits.
