Using this Titan CPU cooling fan is a breeze. First, make sure your computer is turned off and unplugged. Attach the two metal mounting clips to the CPU socket carefully. Then, apply the provided heatsink compound evenly on the CPU surface. Place the heatsink on top of the CPU and secure it with the clips. Connect the 3 - pin connector to the motherboard fan plug. When your computer is on, the fan will start working automatically. As for maintenance, it's a good idea to check the fan regularly for dust. You can use compressed air to blow away any dust buildup. If you notice any strange noises or a significant drop in performance, it might be time to replace the fan. Remember, always follow safety procedures when working inside your computer.
