What is the longest time that your PS3 has been running specifically for GT5? Mine has been turned on for over a week now, B-Spec endurance through the night and A-Spec/Online races/B-Spec throughout the day. So far I haven't had any problems and I regularly check it for feeling too hot but it's always just warm. My older brother had his running B-Spec 24 hour races every single day for nearly 3 weeks without turning it off once and he never had any problems, that was using one of the first "fat" PS3's as well (like mine).
