Introduction

The fan and heat sink are components that prevent the device from overheating. The heat sink is usually made out of a thermal conducting metal such as copper or aluminum. Internally the fan has ball bearing that rotate and reduce friction. Over time these ball bearings can fail causing noise and eventual cause the fan to stop working.
