I've had my PS3 on for months without shutting down. I never got one message saying it was too hot.....hell I didn't even know they would inform us in the first place. Just keep it ventilated and you'll be fine.
yea, that's what I figured...
a messaged just popped up on the upper right hand corner while I was playing COD4 saying it was getting hot and to turn it off... I realized the fans weren't turned on in the enclosure afterwards...

On other note, I found out yesterday if you shake the controller a little the camo goes back to normal

it was by accident too
