As you might already know, Intel’s Sandy Bridge processors use different Socket, LGA 1155. New socket has always lead to problems as CPU cooler manufacturer had to release new models to support the latest socket or produce additional mounting plates for already announced solutions in order to fit the cooler. This time its different.

According to technical documents for Intel LGA 1155 Socket, the distance between mounting holes for cooling system is 75 mm. The same numbers are mentioned in specification for LGA 1156 Socket.

Intel LGA 1155 and LGA 1156 Socket dimension details

As its clear from the graph, measurement data for both LGA 1155 and LGA 1156 Sockets is the same. Therefore, to cool new Sandy Bridge processors with LGA 1155 socket, one can freely use cooling solution that have support for LGA 1156 Socket processors.

This fact was also confirmed by Thermalright:

All our models that support the LGA 1156 are naturally compatible with the Sandy Bridge, the LGA 1155. As the LGA 1155 shares the same screw hole design, you can just purchase the LGA 1156 BTK if you wish to upgrade your old Thermalright tower coolers to Sandy Bridge platform.

and a big thanks from me too! was worried whether my cooler master hyper 212+ would really fit my 1155 motherboard since the manual is only about 1156 :)
