Drop-in replacement for standard Intel coolers

SecuFirm2™ is fully compatible with the original Intel installation system so that the coolers work as a simple drop-in replacement.

PLEASE NOTE - The Xeon 1366 coolers can only be used on motherboards 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 don’t have such a backplate. Please choose the NH-U12P SE2 for these motherboards.
