How I Stopped My Laptop from Overheating With Compressed Air
So my gear gets around. I don’t drop it or crush it like some people, but it doesn’t get the baby treatment either. Sometimes I’m writing articles in 38c temperatures, dripping sweat on the keyboard with every keystroke. Other times I’m editing photos in dusty towns in rural Myanmar / Burma.
And that gets my laptop feeling very angry (hot).
In fact, it had been about a year since I last gave it a good cleaning, and it was getting hot to the touch. Seriously hot. Like “ow, don’t touch that part of the laptop again” hot.
A laptop has a bunch of electronic components in it, and surprise, they get warm during use So warm that most require some sort of internal fan to circulate air and keep it cool. If the temperatures are too warm for too long, you may experience performance issues, errors, and premature hardware failure. Yes, it can kill your laptop.
You see, when a laptop is in a safe, clean (read: boring) environment like an office, overheating isn’t much of an issue. On the other hand, when there’s so much dust around that you need a mask to keep it out of your lungs, imagine what’s accumulating in your laptop?
For many laptops, it’s a fairly easy process to blow out the dust that is caught inside. You’ll need a can of compressed air which you can pick up at many stationary-type stores or computer shops.
Note: Some Ultrabooks and some Macbooks are fairly sealed off, and the only way to really clean out the insides is to have it disassembled. We don’t recommend that you take your laptop apart unless you really know what you’re doing.
- Shut your laptop down and unplug it from the wall and other peripherals. It should be completely off, not just put to sleep.
- Flip it over, and check the sides. You’re looking for the air vents. These are our targets.
- While keeping the compressed air can UPRIGHT, give several short (0.5sec) blasts toward each of the vents from 15cm / 6in away. It is very important that you do not tip the can sideways or upside down, as the chemicals will come out and spray onto your laptop. This is bad.
- A few blasts in each area should be enough, and you may see some dust flying out. Don’t overdo it.
- Flip your computer back over, and boot it up. That’s it.
Note: If you’re a little afraid of tackling this yourself, find a local computer shop and ask them to blow it out for you.
I used the free software program SpeedFan for Windows to give myself a before and after look at the difference a few puffs of air can make. You may see a different set of titles depending on the sensors in your laptop.
My laptop no longer feels like it may spontaneously combust, and the fan that sounded like a plane preparing for takeoff is now just a quiet purr.
