My laptop fan is really loud, so I downloaded Speedfan. It said my temperatures were REALLY high, like high as in core temperature was 93 degrees celsius, so I blew into the fan compartment to try to clear out dust, but it made this really weird noise and it looked like something that wasn't dust came out. I didn't want to do it again to find out... Was that bad? I left it overnight and now it's a lot quieter and my temperatures are almost normal, but it seemed like blowing into it was a bad idea? Should I stick to doing that or buy compressed air?

 

 

 

EDIT: I just noticed it's blowing air out of it now, I don't think it was doing that before? Or at least I didn't notice it.

Clearing some of the dust in that thing was definitely the right thing to do. Only thing is that I remember my laptop fans sucking air in to keep the core cool, but if it's keeping your machine cool enough, then it should be alright.

You should still bring it to a computer shop to make them clear the dust, opening a laptop is not as easy as opening a desktop to get the dust out of them.

Agreed, you would be amazed at how the dust collects on the inside of the vent, and you can easily kill your laptop by opening it up if you don't know what you're doing.
