why not consider 110v boxers? No PS needed and they come in a variety of air flows.
At current my TV and PS3 both sit on top of a chest of draws. Come November I will be getting a PS4, so in order to accommodate both consoles, I plan to remove the top unused draw below the TV and use that level as an open shelf (approx. 660x180x390mm)to house both machines. However I am concerned about overheating, due to the build up of heat from the consoles' exhausts. And as the drawers are backed right up against a wall, removing the back would do little to improve ventilation.
The plan is to use a low noise PC case fan at the bottom rear of each side panel of the shelf, to draw the hot air directly from the consoles' exhausts, out horizontally. I'll connect the fans to a fan speed control device, and wire the device's power to a 12V AC/DC wall adapter (instead of a computer PSU, as it was intended to be).

Will this set-up work okay ? I'm still unsure of the fan voltage, I'm assuming it will work at 12V (the listed rated voltage). But what is the Start voltage(7V)? Does this mean the fan can run anywhere from 7-12V? Also would the wall adapter need to be regulated?
This is my first time doing anything like, so I'd really appreciate any answers/advice.
