Noctua NH-U12DX 1366 CPU Cooler for LGA 1366 Xeon
Based on Noctua's signature NH-U12 series and fitted with the award-winning NF-P12 fan and NT-H1 thermal compound, the NH-U12DX 1366 forms a complete premium quality package that provides outstanding quiet cooling performance for Intel's LGA1366 Xeon 5500 CPUs. The new SecuFirm2™ mounting system for LGA1366 is highly convenient and makes the NH-U12DX 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-U12DX 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.
