Overheating ps3 when playing

help, Ive been playing prototype and i get overheated or something and the game freezes. Ive been searching for an inter-cooler and cant find one. Can you guys help me as to why my s3 keeps on overheating or something? I lay resonance or fate and it works fine before i played prototype. Its happens every 20-30 mins I think? it started on friday.

ok now the console is starting to freeze ALOT. Now it won't even instal ENDWAR correctly also now i can only play prototype for 20 seconds(yes I timed it.)redframe01

you better not play with it at all now,because it may break up,I think your problem is the thermal compound ,one of the people have put a topic about that here is the link of it

Is it an older model? If so then its about this time when they are starting to act up and die out on people. My Fat one died out on me in December, My advice is if you have the money get a slim, but only when your fat one dies out on you.

I have a 60 gig launch model last week i was playing and the screen went blackfor about 30 seconds so when it came back on I shut it down. I plan on backing up all my info when I try it again in case it breaks.

Make sure to back your saves up.
