View Full Version : Cleaning Laptop Air Vents

10-01-2010, 11:53 PM
I really need to clean the vent on my laptop because it has overheated once or twice. I considered using a can of compressed air to blow into the vents but wouldn't that just shift the dust to another part of the computer rather than actually remove the dust?

I would love to take it apart but it has a 3 year warrenty (came for free so I said yes) and I don't really want to void that!

So I was wondering whether or not it would be ok to just run the vacum cleaner along the bottom of the laptop and over the vents to suck the dust out? Would this be ok or will I break something?!?

Yes if your careful a vacuum cleaner will do fine

Static electricity no?

Only if your vac tube touches sensitive gear inside the box.
Doing it from outside the vents should be fine.

Vacuum probably won't do much unless it's very powerful, compressed air will shift dust much better but then like you say it's hard to get out.

If you can blow compressed air in one side and suck it out the other side with the vacuum you might get somewhere.

But the best way of doing it is to take it apart and clean it properly. Unfortunately the warranty prevents this!

My mate used the upholstery attachment on his vacuum cleaner so he could make a kind of a seal over vent.

I cranked the air compressor up to 120 psi and blew rom bot inlet and outlett ports short bursts and the laptop has never been quieter... Did this 2 months ago and no fan problems

Yeah you probably blew the fans into pieces :p

But seriously, too high pressure compressed air can break SMD components clean off motherboards

Use the brush end of a vacuum cleaner.

Can anyone confirm if the spinning fan creates a current and can be dangerous for the laptop (or a desktop)?? I heard this once and always hold or stop the fan spinning if i am cleaning them out...
