Macbook Pro early 2011 banging!

[Dannyshing27]

Hello

I have a macbook early 2011 2ghz i7 with 16gb Ram that until recently has been working flawlessly.

However in the past day a loud banging noise can be heard every now and then from the back of the laptop. I have opened the laptop to see if I could figure what was wrong to no avail. I should also mention that the laptop uses two SSD (one in an optibay) so there are very few moving parts

please help!

can be the fans check the bottom plate for dents or marks which will be indicated on the dust coating it. Also just check the logic board for any signs of burns or anything just to clear any doubts
