Push pull would likely be preferred yes, but more so if the fans were blowing down. If they are blowing up, sucking from the base, depending on how much pressure differential they are creating, and how close the base of the console sits to the floor, dust could certainly be an issue. Thermal expansion, yes. As the air goes up it deals with less pressure and loses energy, making it cooler. When it's windy out though, depending on how windy, the hot air will mostly go sideways, but also up. The difference is an open space is quite a bit different than an enclosed, if not sealed space. Not to mention controlled vs constant variation. An enclosed controlled console, in an enclosed controlled building, with fans blowing down through the console, will receive little to no thermal expansion resistance. The entire room will have roughly the same air pressure and temp, so forcing air down though the console would be easy, depending on how the internals are laid out. |
Dust shouldn't be much more of an issue than any other console really. Depends on how much CFM they are pushing.
In an environment where there isn't much "breeze/wind" the hot air will rise as consoles are typically contained in a "compartment" like on a shelf under the TV in a unit. - You don't want to be sucking the warm air from top to push it out the bottom.
It's hard to explain, but when I had the fire stations thermal camera the top few inches of air in my cabinet where my console resides was warmer than the rest due to hot air rising from thermal expansion.
Either way, Microsoft has likely done the appropriate testing and ascertained which approach is suitable for them, highly doubt we will ever see a RROD v2.0 ever again.
