Noctua just sent over a note about their latest CPU coolers which are specifically made to keep the Intel Xeon running nice and cool.  There are two of them, the NH-U12DX i4 and NH-U9DX i4. The U12DX is running 120mm fans while the smaller U9DX is running 92mm fans. The coolers are made to keep things cool and quiet as expected from Noctua. They’ll be available shortly with pricing of EUR 59.90 / USD 64.90 (NH-U9DX i4) and EUR 69.90 / USD 74.90 (NH-U12DX i4).

Noctua today presented a new revision of its much acclaimed NH-U12DX and NH-U9DX quiet CPU coolers for Intel Xeon workstations and servers. The new i4 models support LGA2011 (both Square and Narrow ILM), LGA1356 and LGA1366 based Xeon platforms and now come with PWM fans for automatic speed control. Fitted with the professional SecuFirm2™ mounting system and bundled with Noctua’s industrial-grade NT-H1 thermal compound, the NH-U12DX i4 and NH-U9DX i4 form complete premium quality packages for quietly cooling Xeon based workstations and servers.
"Builders of quiet workstations and servers still have trouble finding quality cooling solutions for Intel’s LGA2011 socket with Narrow ILM mounting", explains Mag. Roland Mossig (Noctua CEO), "so we’ve decided to update our DX line of coolers to work with both Square ILM and Narrow ILM based LGA2011 platforms. At the same time, we’ve added PWM control and switched the U12 version to the new, slimmer layout of the NH-U12S, which not only provides better performance but also ensures easier access to the RAM slots, which was another long time request from our industry partners."
Supporting Intel’s LGA2011 (both Square and Narrow ILM), LGA1356 and LGA1366 Xeon platforms, the SecuFirm2™ mounting included with the NH-U12DX i4 and NH-U9DX i4 has been custom designed for system integrators who require both perfect contact pressure and quick, convenient installation.
Both the NF-F12 120mm fan of the NH-U12DX i4 and the two NF-B9 92mm fans of the NH-U9DX i4 now support PWM for fully automatic speed control. In addition, the maximum fan speed can be reduced using the supplied Low-Noise Adaptors for even quieter operation.
Thanks to its slim design with only 45mm fin depth, the NH-U12DX i4 ensures easy access to the RAM slots. When installed parallel to the slots, it will not overhang the memory on LGA1356, LGA1366 and LGA2011 Square ILM even with two fans installed, thus providing full compatibility with tall RAM heatsinks.
While the superior cooling performance of the NH-U12DX i4 makes it ideal for quiet workstation builds, the 125mm height of the NH-U9DX i4 makes it fully compatible with standard 4U server cases.

Pricing and availability The NH-U9DX i4 and NH-U12DX i4 will be available shortly at suggested retail prices of EUR 59.90 / USD 64.90 (NH-U9DX i4) and EUR 69.90 / USD 74.90 (NH-U12DX i4).
