My MacBook doesn't cool properly

My macbook pro isn't cooling properly anymore and also it is making an awful lot of noise, my dad says it's because there is dust inside it. I don't dare to open it up because I'm scared that I won't be able to put it back together. my question is: Is it safe to open the back of my computer to remove possible dust from the fan?

I need help.

Hello Douwe,

Don't be scared of opening up your computer. As long as you have the right tools, you should have no problem cleaning up any dust inside the computer. Here is a guide on how remove the fan, if that is the route you should choose.

It is also likely that the thermal paste should be reapplied. After a while, the thermal paste on the processors can go sour, causing symptoms just like you described. This guide will show you how to get the heat sinks off.
