of course la, the fan is not that strong enough to circulate the air to the front, plus it is an enclosed area, with a little hole at the back I see, there are little or no air flow inside the cabinet, not good for your ps3. Ideally, you need to put it outside i.e open air area where there are sufficient cool air around.

hmm, put on top of a small table in front of the cabinet also can as long as it's outside in the open
