As you use your computer, the hard drive and other devices in the computers central processing unit (CPU) can heat up and cause your computer to run very slow or even stop completely. To prevent this, a fan has been installed in your CPU, and is vented out the back of the case for your desktop computer. This allows the interior hardware to remain cool and continue working normally. Regular inspection and troubleshooting of your CPU fan will keep your computer running and may even extend the life of your system.
1.Check the location of your CPU to verify that the back of the case is not up against a wall or being covered up by and loose materials. If needed, relocate your computer to an area where it can vent out the back of the CPU properly.
2.Turn the computer off and remove the case from the CPU by undoing the screws in the back of the unit with a screwdriver. Slide the case forward and remove it from the CPU base.
3.Locate the CPU fan on the inside of the unit near the back and check for any dust or debris around the fan. Use a can of compressed air to remove the dust from around the fan. Check the back of the unit where the air is vented out for any signs of dust build up as well and use the compressed air to clean it away.
4.Follow the electrical wires from your CPU fan to the power supply and remove any dust from around the electrical connectors in the power supply with the compressed air. Unplug the connectors and check for any signs of decay or anything that would prevent their normal operation. Once you have inspected the electrical connectors, reattach them to the power supply.
5.Turn the computer back on with the top of the case still removed and check to see if the fan is working normally. If the fan is still not functioning, you will have to replace it by unscrewing it from the back of the CPU and installing a new CPU fan.
6.Slide the CPU cover back over the top of the base when you have completed your troubleshooting of the CPU fan. Secure the cover by reattaching the screws in the back of the unit with a screwdriver.
