I dun think Max 5 hours a day is a problem....


I once play my PS3 fat from 12pm till night 9pm none stop no problem
Then play Army of Two with my fren from morning 11am play till night 8pm no problem
Then Resident Evil 5 from 3pm afternoon straight play till 1am none stop also no problem
Even with Uncharted 2 i play like 8pm play till 3am also no problem although the fan was noisy like hell.

So i guess the 5 hours max stuff does not apply.... at least for PS3 fat.
