- Attach fan to heat dissipater with screws, using spacers between.
- Attach fan/dissipater to chassis.
- Situate mounting ring according to diagram.
- Place special screw extenders into mounting ring.
- Apply thermal paste to the center of the CPU mounting position on the motherboard.

A 3-pin case fan can easily be connected to a 4-pin connector on the motherboard. The fourth pin is simply left blank in this configuration. In most cases, it will then run unregulated at a fixed speed. Some newer boards offer the possibility to adjust the fan speed by voltage.
Can a 4-pin fan connect to a 3 pin motherboard?
Yes! PWM fans come with a 4-pin connectors for fully automatic speed control via your mainboard’s 4-pin PWM fan headers. Please note that 4-pin fans can also be connected to your mainboard’s 3-pin fan headers though.
How do I connect 4-pin fans to PSU?
If you want to connect any fan directly to a PSU power source so that it runs full speed all the time, you will need a small adapter. The PSU output most often used for this is a female (with holes) 4-pin Molex connector about 3/4″ wide, with four round holes in a straight line.
