Figure 10 shows the Blizzard T2 with the Intel stock-like pressure clips installed, compatible with LGA775, LGA1150, LGA1155, and LGA1156 CPUs. For use with AMD processors, there is a simple lever that makes it compatible with all sockets.
You must remove the fan before installing the cooler, for better access to the pressure clips. Just press all the four clips to secure the heatsink in place.
After that, just fit the fan to the heatsink.
