“It is shocking how well these three high-end heatsinks from Noctua handle AMD’s TR4 and SP3 sockets for their latest Ryzen Threadripper (X399) and EPYC platforms.”

“I’m still glad to see that aircooling is a viable solution for hot chips like the Ryzen Threadripper 3960X that still allow the processor to fully utilize the extents of the platform while still keeping temperatures in check.”

“The end result was that you have options even if you don’t want to water-cool your Threadripper build... with one of these coolers you get exactly what you expect for as long as the fan works, and if that happens it is an easy fix... all three of the...”

“So there you have it, overall we feel the Noctua U12S and NH-U14S coolers are very nice, the looks are a matter of taste, the performance winner, however, is the NH-U14S TR4/SP3.”

“The NH-U9 TR4-SP3 should most definitely reside on any builder’s list for a compact Threadripper build.”

“Pokud tedy máte z nějakého důvodu málo místa tam, kam se snažíte X399 a ThreadRipper nacpat a U14S se vám nevejde, jsou U12S a U9 určitě možnosti. Zejména U9 se vejde do klasických racků a vzhledem k rozměrům docela překvapí, že je vůbec schopna tohl...”

Key features

Compact 92mm size for best compatibility

Thanks to a total width of only 95mm, the NH-U9 TR4-SP3 provides 100% PCIe clearance and never overhangs the top PCIe x16 slot. At the same time, its height of only 125mm allows it to fit smaller cases and most 4U size rack-mount enclosures.

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!

Dual NF-A9 PWM fans

The NH-U9 TR4-SP3 is equipped with two of Noctua’s award-winning NF-A9 PWM 92mm fans. This push/pull dual fan configuration allows it to achieve a level of quiet cooling performance that is remarkable for such a compact cooler and comes close to the bigger NH-U12S TR4-SP3.

NT-H1 thermal compound

Noctua's much-acclaimed NT-H1 is a well proven pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability, which makes it suitable for use in professional server and workstation environments.
