About a year ago, I purchased a secondhand PS3 slim from my buddy. After a couple of months the fans started being extremely loud. I decided to ignore it but a few weeks ago a "Your PS3 is overheating, please turn it off,etc" message popped up so I stopped playing for a while. I tried the fan cleaning trick and dusting and vacumming parts of the PS3(I never opened it up). I tried placing it in a vertical position and ensured it had proper air circulation and it seemed to help at first as the message never popped up again. I only played it sparingly afterward and only remasters(ICO, Okami) and the message didn't pop up again. Then a week back I tried to play GTA V but the overheating message popped up barely a minute later and the console shut itself down. I tried directing a fan on it but the same thing happened when I tried to replay GTA V. I've not turned it on since as I fear I might damage it further( if I haven't already). Can I do anything to fix it? Cheers GAF.
