hmmm PS3 running where got cool...
will get warm... when i attach the fan... and when you put ur hands on the air out take it feels really warm..
funny tho... i setup my PS3 in its vertical fashion.. the back of the PS3 with all the other ports HDMI, Power port area feel warm.. (tats where i attact the fan) but at the top of the PS3 feels cool..
The PS3's top vents(at a verticl position) and the vents above the USB ports acts as vent-intakes for the PS3, not as a vent for air-dissipation.
Also, the PS3's fan design is not the same as the 7/9-bladed arc fans you see commonly on PCs.
The fan blades aren't curved, but instead they are made absolutely in a vertical form.
Here is how it looks like:

The fan draws in air from the top vents and bottom vents and then exchaust it out through the back. A much better design than the 360, which only places 2 fans at the back and exhausting hot air.
An extra fan at the back isn't needed at all, and infact can actually disrupt the optimum airflow of the PS3.
