How do I get my laptop fan quiet again?

I have a question because I don't know what to do anymore. My laptop, which I've had for almost a year, is something (broken). So the fan on my laptop has been very loud lately and I've tried many things to turn the fan down again, but nothing worked. I've even restarted the system and even that didn't work. Since I haven't had my laptop that long, no dust has collected either. Does anyone have any idea how to stop the problem?

How do you know how much dust has accumulated? It has nothing to do with age, it depends on where the thing is.

If he has a bearing damage then only swapping helps. If something is in the way then cleaning helps. Dirt can sometimes collect in a few days.
