never had a problem with my slim silver ps2,it looks great,plays great and is fully loaded,remember this ps2 has the network adaptor built in were the older models you have to fork out 30 quid for,so thats a bonus in its self,the only reason it could over heat is if you have poor venitlation for the console,e.g haveing it on the carpet,is near a radiator or other warm apliances,the slimline ps2 has to be well ventilated,to let cool air cerculate as with any appliance,wether it be dvd players or xbox 360s any thing if it cant breath it will get hot,and what a cool feature it turns itself off if its to hot means you been on there to long and need a break and the ps2 is telling ya it does to,this is still one of the best consoles on the planet for games library and entainment,and it also plays ps1 and ps2 games and dvds what more could you want,bargain in my opinion
