One heatsink retention module (BKT-0005) and two screws are included in the retail box. Once installed, these are used to help attach the heatsink to the CPU. To install, position the module so that the CPU backplate standoffs insert through the holes on the heatsink retention module and the four feet on the module contact the motherboard. Secure the retention module to the backplate with the two screws provided. See Figure 2-1.
Note: BKT-0005 is included for use with third-party heatsinks only. When installing
aSupermicro heatsink (SNK-P0026), only BKT-0004 (CPU backplate) is needed. The BKT-0005 retention module was designed to provide compatibility with clip- and-cam type heatsinks from third parties.
