I've read up a little on some instances where people who have the older "fat" PS3's have experienced it shutting down due to the fact the older version had trouble processing and running GTA 5.  Supposedly prior to the meltdown the fan was running very hard to keep system cool. Eventually it conked out.  

As it turns out I have an older PS3 (maybe 4-5 years old) and have purchased GTA5. I don't think I have noticed any unusual amounts of the fan running but now I am paranoid.

Any truth to this story?
