Before you begin, touch a metal part of the case to discharge any static electricity from your body, and keep your fingers away from the circuit boards. Dust likes to collect around the fan, ventilation holes, and disk drives. Try to vacuum the fan blades, too. If you can't get the tip of the vacuum between the blades, gently wipe them off with a cotton swab. Some fans have a filter where the fan is mounted. If you're really ambitious, remove the fan (be careful with the wires) and clean the filter. (Alternatively, take your PC outside and blow the dust out using your can of com pressed air. Be careful spraying the air against internal components. Compressed air can be very cold and can cause condensation to form on sensitive electrical components.) You can use a can of compressed air to blow dust off external peripheral devices as well, such as your keyboard and speakers.
