Noctua announced three new 92mm 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 92mm 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."

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."

The manufacturer suggested retail prices are as follows:

• NH-U9S: EUR 54.90 / USD 59.90
• NH-D9L: EUR 49.90 / USD 56.90
• NH-D9DX i4 3U: EUR 56.90 / USD 59.90

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.
