Noctua NH-U14S, Premium CPU Cooler with NF-A15 140mm Fan (Brown)

Product Information

With six heatpipes, a fin surface area of more than 6000cm² and two highly optimised NF-A15 140mm fans, the NH-U14S TR5-SP6 provides a superior level of quiet cooling efficiency. Please note that the APH Numeric Rating system is based off our proprietary guidelines in the Review Focus, and should not be compared to other sites. The renowned NF-A15 140mm premium fans supplied with the NH-U14S TR5-SP6 support PWM for convenient automatic speed control through the motherboard, which allows them to run near silent at lighter loads and speed up only when necessary. Topped off with the pre-applied NT-H2 thermal compound as well as the professional SecuFirm2 mounting system for TR5/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 TR5-based Threadripper workstations and SP6-based Epyc servers. H. with the Taiwanese cooling specialist Kolink International Corporation, pooling more than ten years of experience in the development, manufacturing and marketing of high-end cooling components.

Please also keep in mind that other components such as narrow or small cases as well as memory modules with special (higher) heat-spreaders can cause compatibility-issues. While the large, six heatpipe design and the NF-A15 140mm fan with PWM support for fully automatic speed control allow the cooler to best the renowned quiet cooling performance of all other U-series coolers, its 52mm slim shape still guarantees full compatibility with tall RAM modules on AM5/AM4. Those heatpipes then go through the radiator to dissipate the heat into the surrounding environment. With six heatpipes, a fin surface area of more than 6000cm² and the large NF-A15 140mm fan, the NH-U14S TR4-SP3 provides a superior level of cooling performance that makes it ideal for the most high-end, enthusiast-grade TR4/SP3 systems. Supporting Intel LGAS 1200, LGA115x (LGA1150, LGA1155, LGA1156), LGA2011, LGA2066 and AMD (AM4, AM5, AM3+, AM2+, FM1, FM2), the SecuFirm2 mounting included with the coolers guarantees perfect contact pressure and maximum convenience on all current sockets.It's pretty quiet and obviously, the fan is not designed for clear case look-how-pretty-the-inside-of-my-PC-is but does what it needs to do. First introduced in 2017, Noctua’s Threadripper and Epyc coolers have become a standard choice when it comes to quiet, premium grade air cooling solutions for AMD-based workstations and servers. In addition, the maximum speed can be reduced from 1,500 to 1,200 rpm with the included low-noise adapter to enable even quieter operation.

According to the specifications, the Noctua NH-U14S is electroplated with nickel on top of its copper -- which has a thermal conductivity of only 90.

Its outstanding cooling performance, good compatibility and excellent running smoothness make the NH-U14S TR4-SP3 a premium solution for the highest demands. The photo above shows the configuration of the heatpipes more clearly in relation to the base leading into the fin array.

I have had to modify my computer housing to get it to fit, nothing major just a few holes here and there. However, case manufacturers sometimes change parts or details of their products without prior notice or explicitly indicating a revision. Measuring 150mm wide (including fan and fan clips), the NH-U14S provides better compatibility with SLI and CrossFire setups as compared to tower coolers that are wider than 150mm or use fans wider than 150mm. The supplied splitter cable makes it possible to power and control both fans simultaneously from a single motherboard fan header.

Because of the depth of the fan, depending on your motherboard design, it may have somewhat tight clearance with your RAM. While the large, six heatpipe design and the 140 mm fan with PWM support for fully automatic speed control allow the cooler to best the renowned quiet cooling performance of all other U-series coolers, its 52 mm slim shape still guarantees full compatibility with tall RAM modules on LGA2011. I would have prefered to see noise levels and efficiency at idle and at full CPU load instead of these artificial 7V and 12V levels. One tip though, be careful when working inside the case as it is very easy to brush the heatsink radiator and bend some of the fins as they are very delicate.Rubber strips on the heatsink are now superseded by integrated rubber dampeners on the included NF-A15 PWM, used to reduce mechanical noise emissions during operation, as seen in our photo above. For users who want to achieve even better performance by adding a second optional NF-F12 and NF-A15, fans are available to create a push/pull setup. As aforementioned, the fans are even easier to dismount from the heatsink itself compared to the NH-D14.

Topped off with the professional SecuFirm2™ mounting system and pre-applied NT-H1 thermal compound, the NH-U14S DX-4677 forms a complete premium quality package for quietly cooling LGA4677 based Xeon workstations and servers.Use of these and any missed payments may affect your ability to obtain credit from Klarna and other lenders. Having the paste pre-applied to the heatsink base ensures optimal bond-line thickness and saves precious time in installation. One manual is included for each socket type for a total of three installation posters, placed in their respective boxes.
