PS3 freezes after few minutes of GTA V

[Cola]

Hey guys,

Everytime I play GTA V on my PS3, singleplayer or multiplayer, the console freezes completely after about 5-10 minutes of playing. I can't even do one mission or job, and go back and save my game before it locks up completely.

The textures go bad, and the sound gets stuck. Only thing I can do, is to do a hard shut down on the PS3.

I have tried several cooling solutions. From leaving it be where it normally is, with only it's own fan cooling it. To putting it right next to an open window (2ºC outside) to get fresh cold air at the front intake, and having two 80mm fans placed at the top of the ps3, to suck out hot air from the vent.


Here's a drawing.
Cold intake air is marked with blue arrows, and hot exhaust air is red arrows.





Appreciate any help.
Regards, Frederik
