Using this cooling fan is easy. First, identify the suitable location in your computer case or power supply where the fan will fit. The 80mm x 80mm x 15mm size makes it a standard fit for most cases and power supplies. Connect the 3 - pin connector to the motherboard fan plug. Once connected, turn on your computer and the fan will start working. As for maintenance, keep an eye on the fan's performance. If you notice an increase in noise or a decrease in cooling efficiency, it might be time to clean the fan. You can use compressed air to blow away dust from the blades and the housing. When handling the fan, be gentle as the ceramic bearings are delicate. Also, make sure your computer is turned off and unplugged before any maintenance or installation to avoid electrical hazards.
