There is no doubt in anyone’s mind that Noctua is among the top manufacturers of CPU air coolers. They are also the makers of one of the best and quietest fan series we have ever had the pleasure of using. The one drawback to Noctua’s amazing air cooling solutions is their size being either too big for most or too small for general applications. Looking to provide more options for customers in the middle, Noctua has three new 92 mm coolers.

The new Noctua NH-U9S, NH-D9L, and NH-D9DX i4 are set to provide the same great cooling performance you expect from their bigger brothers. The compact designs and placement of the NF-A9 PWM ensures a small footprint, so these work with HTPC and SFF cases. They only require 95 mm x 95 mm for mounting. If the fan will fit flat in the space, the cooler will as well. The NH-D9DX i4 is the same cooler as the NH-D9L, but it comes with an LGA pro-grade SecuFirm2™ mounting system.

What more can you say about Noctua? You are getting a great cooler, some of the best fans on the market, and high-end thermal compound in the NT-H1, all for $59.90 US. You can easily spend more than this trying to match these up with separate items. If you need more information, turn your bass up and watch the videos below. Or you can be boring and read the full press release below those.


Vienna, November 12th 2014 – Noctua today announced three new 92 mm class CPU coolers. Whereas the NH-U9S and NH-D9L are retail models that suceed the popular NH-U9B SE2, the NH-D9DX i4 3U targets Intel Xeon LGA2011 based workstations and servers. All three models use the recently announced NF-A9 PWM 92 mm premium fan to achieve class-leading quiet cooling performance.

“Providing a great balance between high efficiency and compact size, the NH-U9B SE2 is still one of our most popular models”, says Mag. Roland Mossig (Noctua CEO). “The NH-U9S and NH-D9L stay true to this proven formula but now offer even better performance, better compatibility and PWM support for automatic fan speed control.”

Continuing the renowned legacy of Noctua’s award-winning NH-U9 series, the NH-U9S is a premium quality quiet CPU cooler in classic 9cm size. Its asymmetrical design with 5 heatpipes not only provides even better cooling performance than the previous generation but also improves compatibility: Thanks to its 95 x 95 mm footprint, the NH-U9S clears the RAM and PCIe slots on all Intel and most AMD based mainboards, including µATX and ITX.

The NH-D9L features 4 heatpipes and is 15 mm lower than classic 9 cm coolers such as the NH-U9 series (110 mm vs. 125 mm), which doesn’t only guarantee full 3U compliance but also makes the NH-D9L ideal for compact HTPC and Small Form Factor cases that have airflow paths parallel to the mainboard. Like the NH-U9S, the NH-D9L has a 95 x 95 mm footprint and thus provides 100% RAM and PCIe compatibility on all Intel and most AMD based mainboards.

The NH-D9DX i4 3U is the same heatsink as the NH-D9L but comes with LGA2011 mounting for both Square ILM and Narrow ILM Xeon platforms as well as support for LGA13x6.

“Our DX i4 series are renowned among builders of LGA2011 based Intel Xeon systems and one of the few available quiet cooling solutions for Narrow ILM platforms”, explains Mag. Roland Mossig (Noctua CEO). “With the new NH-D9DX i4 3U model, we can now offer a cooler for 3U cases that offers similar performance as the previous 4U model NH-U9DX i4.”

All three new models come with the new NF-A9 PWM for further improved quiet cooling performance. Topped off with the trusted, pro-grade SecuFirm2™ mounting systems, Noctua’s proven NT-H1 thermal compound and full 6 years manufacturer’s warranty, the NH-U9S, NH-D9L and NH-D9DX i4 3U are premium grade solutions through and through.
