How to clean your laptop's cooling fans
Dec 19, · 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, . How to clean a laptop fan without compressed air? If you do not want to use a compressed air can, you can also clean the fan by a vacuum cleaner. Another way of cleaning the fan is by opening the laptop. Unscrew the bottom panel (and keyboard panel in some cases). Disconnect the cables of the fan. Clean it with the help of a cloth.
I've written about this subject in years clwan, but it's so important I feel obligated to repeat myself for those who might have missed it. 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 ln an air compressor—though tread lightly how to restring an umbrella clothesline 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 t 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 clexn 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.

Apr 09, · If the brush is not clean enough, you can use a wet cloth wipe the blades of the fan. In order to reduce laptop fan noise, you can pull out the fan blades with a little effort. Use a cotton swab to damp the lubricant and apply it to the fan shaft. Also apply a little on the fan base, especially the contact area.
Your laptop may even reduce its performance to stay cool. This presents a serious problem. You could dust out a laptop in a similar way— if only there was a way to open it up and get inside.
Your laptop may have a bottom panel or several bottom panels you can unscrew to access the internals. If a service manual is available for your laptop, it will walk you through the process. Depending on your laptop, opening the panel may or may not void your warranty. Use a can of compressed air to blow out the internals of your laptop. Be careful when blowing air at the fans in the laptop — if you make the fans spin too quickly, they could be damaged. Blow at the fans from many different angles, using short blasts of air.
We recommend compressed air — also known as canned air — for a reason. But dust does build up inside a laptop, whether you can open it yourself or not. Exercise caution when doing this. If you aim a blast of compressed air directly at a cooling fan inside a vent, you could cause the cooling fan to spin too quickly. How often you need to clean your laptop depends on the laptop itself and how dusty your environment is.
