After the CPU is securely seated, install the appropriate cooling device. We strongly
recommends a heatsink/fan combination. Consult with your retailer for other
cooling options. See the figure below to install the heatsink/fan.
Locate the cooling fan connector J1 on the motherboard. Plug the CPU's cooling
fan cable into the cooling fan connector on the motherboard.
There will be a plastic clip assembly that will force you to connect the
fan cable correctly.
