Hello CFLORES00552 and welcome to the forums
That doesn't sound at all healthy! But let's see what we can do to sort it all out for you.
I would suggest holding a vacuum cleaner to the fan vent (perpendicular to the fan) and let it suck all of the crap out for a while. You will be surprised how much will come out, when I did this so much stuff came out, I still don't know how the fan was able to spin before then!
Top right, you will see the fan intake, put it on there and turn it on
Do this for about 2 minutes, moving it around on that vent.
Let us know how this goes
Maybe we will have to take your computer apart if this doesn't work, give it a proper clean out
