Using this fan is easy. First, find a suitable spot in your desktop or laptop computer equipment where the fan can be installed. Connect the 3 - pin motherboard plug to the appropriate slot on your equipment. If you're using it in a 2 - wire application, just ignore the middle wire. When it comes to usage, make sure your equipment is powered off before installing or removing the fan. Also, keep the fan away from water and other liquids. For maintenance, regularly check the fan for any dust or debris. You can use a can of compressed air to gently blow away any dirt. This will help keep the fan running smoothly and quietly, and extend its lifespan.
