Hi, I've got few days ago PS3 (I know i'm late xd) anyway, i'm aware of huge problem on PS3 which is overheating. So with my modded PS3 I also got modded housing which has holes above fan. Also to mention, I'm keeping my PS3 on open shell, so heat doesn't stay close to PS. Is this good enough to keep it from overheating? P.s. Do I also need to change thermal paste with all that?
