If you have problems with it overheating try getting a Ps3 Cooling Fan to protect it.
Never use a cooling fan as most take the power away from the PS3 and have known to caurse more damage than not having one.
Ps3 do not tend to over heat unless it is faulty which does not happen as offten as the old PHAT versions.

Sony are stabbing their loyal family customers in the back - We have 3 PS3s and 3 PSPs all on the same IP address and all registered with Sony. Why can't we use them at the same time anymore?
Of course it does. Sony designed all PS3 models to overheat. /sarcasm
Seriously, no it doesn't. No PS3 console was designed to overheat. Some did, and this could be down to where the consumer had it running or down to a technical fault that occurred whilst it was being built.
If its a technical fault that occurred whilst it was being built then sony must replace the console even if it is out of warranty.
I agree with you, that its a possibility, but I think sony would dispute it.
