The Core2Duo E8400 model, designed with an LGA775 socket specification, requires a compatible socket 775 cooling fan to work properly. Such fans either use screws or plastic knobs to fasten themselves to a motherboard, unlike the fans from previous socket generations that clipped onto the socket directly. The change to a fan that clips to the motherboard led to a much larger cooling-element capacity, allowing the fan to occupy much more space than the previous socket 478 fans.
Instructions
1. Place a drop of thermal grease or paste from a syringe on the center of the surface of your CPU.
2. Use a thick sheet of construction paper to spread the thermal component around the surface until it embraces the core completely.
3. Mount the fan on top of your processor with the metal plate below the fan touching the processor's surface.
4. Push down on the clips surrounding your fan and twist them so they lock. If you have screws on your fan, push them in and use a Phillips-head screwdriver to screw them in.
5. Connect the fan's power cable to the motherboard's "CPU FAN" connector to install the fan.
