Noctua NH-U9DX 1366 CPU Cooler for LGA 1366 Xeon
Based on Noctua's compact NH-U9 series and fitted with the award-winning NF-B9 fan and NT-H1 thermal compound, the NH-U9DX 1366 forms a complete premium quality package that provides excellent quiet cooling performance for 4U Xeon 5500 (LGA1366) workstations and servers. The new SecuFirm2™ mounting system for socket LGA1366 is highly convenient and makes the NH-U9DX 1366 a tailor-made drop-in replacement for standard Intel coolers. To make your Xeon 5500 systems quieter has never been so easy!
Caution: The NH-U9DX 1366 can only be used on mainboards that have a backplate with screw threads for CPU cooler installation (such as the Intel reference backplate for Xeon 5500). The cooler is thus incompatible with Xeon 3500 and Core i7 mainboards that dont have such a backplate. Please choose our NH-U12P SE2 for these mainboards.

Completely pre-installed, the new SecuFirm2™ mounting system ensures maximum convenience and extremely short installation time.
Drop-in replacement for standard Intel coolers
