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

Product Information

The renowned NF-A15 140mm premium fans supplied with the NH-U14S DX-4677 supports 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. From my calculations, the total surface area of all the cooling fins combined is actually approximately 0. Use of these and any missed payments may affect your ability to obtain credit from Klarna and other lenders. The question is whether or not the Noctua NH-U14S a proper response to the market, or will it find bad surprises along the way. The TR4-SP3 version is a tailored custom model for AMD’s TR4/SP3 platform (Ryzen Threadripper / Epyc) and features a larger contact surface as well as the latest SecuFirm2 mounting system for socket TR4/SP3.

As different CPUs require different carrier frame types (E1A, E1B or E1C), please make sure to purchase the correct carrier frame for tray type CPUs. Noctua's SecuFirm2™ mounting systems have become synonymous with quality, safety and easy installation. The S-version's 45mm slim shape guarantees 100% compatibility with tall RAM modules and at the same time, its fine-tuned design and the class-leading fans with PWM support provide fully automatic speed control allowing it to further improve its predecessor's renowned quiet cooling performance.

The photo above shows the configuration of the heatpipes more clearly in relation to the base leading into the fin array. Today, Noctua is present in more than 30 countries across the globe and working with several hundred sales partners. Better than expected, it was either this or a 280mm liquid cooler which would probably outperform this cooler but. Nickel, like titanium, is highly resistant to corrosion therefore corroded material won't build up on the surface in the long run.

Unlike many tower heatsinks I have used in the past, the NH-U14S did not interfere with any of my adjacent RAM slots, because it is so thin. Thanks to their superior acoustic efficiency, they are ideal for workstations and servers that run in noise sensitive environments (e.As you can see in our graph above, the NH-U14S was consistently three degrees Celsius lower compared to its smaller brother. On motherboards with east-to-west socket orientation, this can be used to offset the cooler(s) towards the right, increasing clearance towards the I/O panel. 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.

In the same way, the silent heatsink market has changed a lot in the past few years -- consumers are not just asking for acoustic superiority anymore; excellence in cooling is now an expectation. 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. First introduced in 2008, Noctua’s DX line CPU coolers have become a standard choice when it comes to quiet, premium grade air cooling solutions for Intel Xeon processors. Our case compatibility list helps you to quickly identify which PC cases offer sufficient clearance for which Noctua CPU coolers. Noctua however designed both coolers primarily with one thing in mind and that's zero clearance issues with RAM modules (much like the NiC series by Thermaltake and the Archon series by Thermalright) something with which the award winning and quite massive NH-D14 is not very good at.Normally, you will not need to replace the otherwise excellent NF-A15 on the Noctua NH-U14S, but it still needs to be removed during installation.
