The computer is running hot and the fan sounds weird


My name is Leopold. I have an Macbook Pro Early 2011 that is a bit ill. The symptoms is

1. it is running hot

2. the fan sounds weird

3. as an result of that, the battery time is affected.

I have tried making an recording of it with my iPhone 5 and put it on SoundCloud. Here is the link, it is a 10-seconds recording: SoundCloud.

I have also tried using air to blow the fan clean. Still, same symptoms as above.

Anyone have any thoughts on what to do?

Yes, I have searched for it. "MacBook Pro Early 2011 Fan issue" and combination of it. Must be a language barrier because I have found some help but not much.

I have tried it with Mavericks, Yosemite and El Capitan. Same issue. Also, in El Capitan, Eduroam did not function properly.

Thank you Buddhika Mahesh. Much appreciated. A update on what has happened. I bought it as a refurbished B-grade from a company that specializes on refurbished computer. So after reading the guide I look up my receipt and I have still some warranty left. So I was like "I can do it myself, but I have a ton of stuff to do in school and option b is sending it in". So now it is repaired and working better. Next step is to removed the slow, old HDD and replace it with an SSD (Samsung Evo E540 250GB). While at it, I will upgrade from 2x2GB to 2x4GB. Maybe also upgrade to El Capitan. Kind regards, Leopold from Sweden.
