I don't have a heat meter to test this so I just want to ask from a physics perspective what is more likely to be more effective. I noticed that my PS4 gets quite hot. I have it horizontal on a wooden surface. Ideally on top of a metal surface probably it would have been better since heat conductivity for metals is better but I've noticed in many forums people elevating the console in order to reduce heat (putting rubber stickers on the edges). If you elevate the console, you get a flow of air underneath since the warmer air will start moving up and off the edges of the console while cooler air will fill in the gaps. However, air is a worse heat conductor from wood. Sure, the wood does get hot around the area of conduct and it does not diffuse that heat as effectively to the rest of its body but isn't better than just air?
