You see, like desktops, laptops can suck up lots of dust. And because everything in a laptop is packed together so tightly, dust is even more dangerous. When the cooling fans have to run constantly, it’s just a matter of time before the machine start to overheat. When that happens, it may lock up. It may damage system components. And it might even kick the bucket.
Fortunately, as I’ve mentioned before, this is easy to fix. All you need is a small screwdriver and a can of compressed air (or an air compressor—though tread lightly with that, as noted below).
Turn off the laptop, flip it over, and remove the battery. I recommend unplugging the AC adapter, too. Look for an air vent on an outer edge of the laptop; there should be a nearby access panel on the bottom.
Unscrew that panel and remove it. You should see the fan right underneath. Your mileage may vary, but the three laptops I have here all have panel-accessible fans.

Now it’s time to blow out the dust, something you might want to do outside. Hit the fan in short bursts from lots of different angles, making sure to blow most frequently in the direction of the air vent. If you’re using an air compressor, as I did, keep the pressure relatively low, and don’t get too close with the nozzle. Too strong a burst and you could damage the fan or something else.
After you’ve blown out all the dust, replace the access panel and battery, then power up the system. I’ll wager that it runs much quieter (and cooler) than it did before.
If your laptop is more than a year or two old, it’s long overdue for such a cleaning. (Same goes for your desktop.) Don’t wait until it’s too late. And add a reminder to your calendar so you remember to do this again every couple months.
A laptop fan is essential in keeping your laptop cool and reduces the chances of overheating. Learning how to clean a laptop fan can save you money by not taking it to a laptop repair store or laptop replacement parts shop. Here are some steps.
Things you need: Screwdriver, Screws Container, Cotton swabs. In case of dropping and losing screws while removing and attaching them, you can choose to use a magnetic screwdriver, try to label the screws from by part.
Step 1: Unplug the laptop. Turn off the laptop and unplug the battery. It is important that you don’t try to clean a laptop fan with the laptop turned on or the battery plugged in. This will only cause you to end up destroying the laptop and to risk electrical shock or even injury.
Step 2: Remove the RAM cover. Turn the laptop upside down. Unscrew and remove the computer’s RAM cover. The RAM cover is typically located right near the battery compartment. Remove the screws and slowly lift the RAM cover. Remember to put the screws in the container as you take them out. Remember to never force the RAM cover off of your laptop. If it doesn’t want to come off, look carefully at the area and find out what the problem is.
Step 3: Remove the ducts and covers. These are the metal covers over the wide cylinder surrounding the fans, and they are held in place by very tiny screws. You need a number one size screwdriver. Remove the screws very carefully so as not to lose them, especially anywhere within the laptop’s interior.
Step 4: Gently wipe and use compressed air. Wipe or blow away all dust collected on the fan blades and the fan’s copper heat sinks. You need to do this very gently with cotton swabs and small cotton balls to get the big grime off. Compressed air will work best as long as you don’t send the dust anywhere else within the laptop’s interior.
After you finish the above 4 steps, just screw the ducts and covers back on the fan, then re-attach the RAM cover and connect the battery.
