|Cooling is so important!|
One of the biggest threats to keeping your desktop cool is dust. Because of the fans on your computer dust will collect in and around the vents and even on the inside if kept on the floor, near pets or in a room with the windows open or even just a warm environment. With a dry cloth, wipe down the vent panels of your computer. If you are in a very dusty location use a can of bottled air to blow out the dust on the inside of your system. If you aren't comfortable with doing this, contact a professional.
Make sure there is plenty of room around the computer! Airflow helps keep your system cool and if it is blocked, you are raising the temperature inside your computer and putting it at risk. If your computer desktop inside a desk slot, be sure to keep the door open while it is running.
Laptops are notorious for having overheating problems and it truly does reduce the life of your laptop. Never use your laptop where it doesn't get airflow to the bottom, such as "on your lap" or on the bed. Remember that they can still get hot on a desktop which is why I recommend investing in a laptop cooling fan. Many can be found for less than $10 online. Most laptop fans are powered by the USB on the laptop.
Keeping your computer cool will extend the life of your computer and less problems for you in the long run. ☺
