This is because the heat generated by running programs and using the internet escapes through the ventilation system, which includes a fan to help cool down your device.

Over time, dust can accumulate inside this area and make it difficult for air to flow freely – causing overheating! Cleaning your laptop fan is a great way to get it running faster and quieter. You’ll need some compressed air, rubbing alcohol, cotton swabs, paper towels, or tissues for this job. Don’t forget to turn off the computer before you start cleaning!
