Does Sony reccomend a ps3 cooler? i have a link to one..?

First recommendation; do not keep it in the the cabinet while it's in use, even with the door open. Keeping it in a closed area like that doesnt allow for very good air flow. And no, the PS3 coolers actually make things worse and could break your console. All they do is keep the heat censor cool, so when the rest of the console is actually overheating the internal fan doesnt kick in and cool it down. The internal fan inside the PS3 is far strong enough to keep it cool, as long as you keep it in an open area and on a hard service (not carpet).
