Introduction |
The fan cools the internals of a device, allowing it to not overheat while in use. Overtime, dust can block the exit path of the air, which would cause the device to overheat. The fan can also stop working as normal “wear and tear”. When a device overheats, it can pose not only a burn hazard in severe cases but will perform poorly. The response time will be noticeably slower. This is because the internal components of the device are sensitive to heat and can become damaged. [link|https://www.ifixit.com/Wiki/[HP_ 15-ay078nr_ Troubleshooting#Section_Computer_Feels_Hot_and_Performs_Poorly|Here]] is further information to determine if the fan is not spinning and or not adequately cooling the device due to dust or debris.
Before beginning, make sure the back of the device is cool to the touch. An overheated components can cause burns, therefore a cool to the touch device is ideal to work on. |
