Laptop clicking and producing smoke?

[pleasedontdieonmelaptop]

Hi, so I have an approximately 3-year-old laptop which has never had any problems before. I was using it earlier today when I turned it a certain way and suddenly it made a noise very similar to this: https://www.youtube.com/watch?v=i4uU3k_JHWg and it seriously looked like there was smoke coming out of the area between the screen and keyboard (fan? Sorry, I know nothing about computers). I freaked out and shut it down and left it for like two hours. Then I tried to clean the fan with a little vacuum thing as other forums recommended, opened it again and everything seemed fine for about five minutes, until that clicking noise and smoke started again! What do I do and how much will it cost to repair? This is the absolute worst time for my laptop to be having problems, please say it is an easy fix

check with the seller if this is compatible with your laptop as seller's is missing the "L" as in NP530U4B

So the fan definitely is the problem, right?
I don't feel comfortable doing it myself- if I were to buy this fan (assuming it is compatible), could I take it to a repair shop and give it to them to do, and how much would that cost?

check with your local computer store to confirm that the fan is the cause of the noise & smoke plus tell you how much it would cost to repair.
