Locate the power lead for the cooling solution's fan and the CPU fan header on the motherboard. Plug the cooling solution fan power connector into the fan header on the board. It should be keyed, but make sure it is properly plugged in.
Once these steps are taken, the CPU should be physically installed into the motherboard for proper operation. When all the remaining parts necessary for operation are installed, it will be necessary for the motherboard BIOS to either detect or be told what type and speed processor is installed on the board. Please refer to the documentation that came with the computer or motherboard on how to configure the BIOS for the proper CPU model.
