If your MacBook is overheating and/or slow, dust could be the cause

If you have a car, or when in Holland a bicycle, you would take it to a garage or shop to get it checked out every now and again. Specially if you have a feeling that the car (or bike) isn’t quite what it used to be.

Well with computers it’s the same thing. If you look after it, it will return the favour and look after you.MacBooks and computers in general, are finally tuned pieces of equipment we can’t live without them. I know I can’t, I run my business with mine.

I read, I play and I even listen to music now and again, so when the tools we have show signs of wear we need to take heed and give then a little TLC.

Below is a picture of a MacBook Pro fan. There is only one fan in a 13″ MacBook Pro and it needs to work hard to keep the unit cool. So if it’s working harder that it supposed to bad things could happen.

You can see by the image below that it’s not too bad, just a little dust. Upon further inspection of taking out the fan I found the fan blades and the heat sink covered with dust.

Below we see the fan removed and the dust clinging onto the heat sink. This is a killer for MacBooks. If your Mac can’t breath then the fan has to work harder and at some point it will give up and break, when that happens your need to replace the fan.

Even the bottom case is full of dust that’s clogging up the rear vents. this too would cause issues.

Feathers? Really? Yep, found some of those too…

The sooner this MacBook gets a clean the better. This time it worked out fine, I was able to clean out the dust by blowing compressed air into all the vets.

While cleaning some units, in the case below a MacBook Pro 15″, I noticed more dust under the logic board. This had to be cleaned to get to the underside of the unit.

All was well with this unit, thankfully. But if you think your MacBook is not behaving, or the fans sound like a 747 plane trying to take off. Even if you notice the unit getting hotter than you expected then this could well be the cause.

I have had units that have been left far too long in this state and these units have on occasions just died.

There’s a failsafe on Apple Macs where if the unit is too hot it would just shut down as a safety precaution. Often people just carry on using the unit once it’s cooled down, but this can cause other issues later on in the life of the unit.

How is your unit behaving?
