Noctua today released four new CPU coolers for Intel Xeon and AMD Opteron processors. Optimized for use in dual socket systems, the new DX (Dual Xeon) and DO (Dual Opteron) versions of Noctua's highly successful NH-U12 and NH-U9 series introduce the premium quality quiet cooling performance that has become synonymous with Noctua to the world of professional workstations and servers. "Maximum cooling performance at minimum noise levels and excellent reliability can be particularly important when it comes to high-end workstations and special server applications", explains Mag. Roland Mossig, Noctua CEO. "Due to the ever-growing demand for our Xeon and Socket F mounting kits, we decided to design new, customized versions of our coolers that are completely tailor-made for use on Intel Xeon and AMD Opteron systems, especially dual socket configurations. Enter the DX/DO series!"Just to name a few examples of the customizations for server and workstation usage, the NH-U12DX's and NH-U9DX's fin shape has been modified so that two coolers form an air duct on Dual Xeon setups, producing superior cooling performance at very low noise levels. Also, the all new SecuFirm2 mounting system for Socket 771 comes completely pre-installed in order to ensure maximum convenience and extremely short installation time. Fully compatible with the original Intel installation system, the new NH-U12DX and NH-U9DX work as a simple drop-in replacement for Intel's stock cooler.

Both the new DX series coolers and the NH-U12DO and NH-U9DO are fitted with Noctua's renowned NF-P12 and NF-B9 fans as well as NT-H1 thermal compound, making them complete premium quality packages that provide outstanding quiet cooling performance for Intel or AMD based workstations and servers.
