I have 2 PS3 and really wanted to keep them from overheating. I've never had this problem with either of them, but I wanted to make sure I never had. I originally bought a PS3 Mega Power Mini Cooling Fan, this item was a joke. It's not going to stay tied to the PS3 just like that. So I returned it to Revain and bought 2 of these. When you turn on your PS3, this fan will turn on shortly after. To an extent, it's a bit too loud for a small fan, but it seems to get the job done. It attaches to the back of the PS3 unlike the other items that just plug into the USB port on the front of the PS3. After you turn off your PS3, this fan will continue to run for a few minutes before turning off. I have to say it was a great purchase. If I had to do it all over again I would buy this item first and not start with another. If you are worried about your PS3 overheating, I would suggest buying this item, it should protect your PS3 from overheating. If it ever stops working, you'll know because it's loud enough to hear it turn on and off. I have no regrets buying this item and will buy again in the future if one of the fans stops working.
