To try and counter-act some of the heat issues with the Xbox 360, I thought adding some 80mm case fans to the back of the console might help(Since that is pretty much what the Intercool does except this won't fry it) and just cut the wires and us a 12v DC adapter as a power source. But then as I was searching google for tips I ran across this comment on some guys blog:
"The lamina flow of air around propellers is a complex science. Fitting two fans back-to-back does not seem to me to guarantee double the air flow. The fluid dynamics of air flow around fast rotating fans of different size and rotational speed seems haphazard at best. Worse it may actually reduce the air flow . Also if the external fan fails, its blades will block the existing fans exhaust route."

its true.
Also you should be weary of making your x360s fans turn faster than they should, since this could actually generate overcurrent since almost all electric motors can work as generators.

buy a little aircon for your x360 (not a humidifying one of course).

Ok thanks for your help. One more question though, would it be safe and/or efficient to just put one fan on the right side of the console (when it is sitting on its side) and blow air into the unit?

If you are just trying to blow air into your x360 like a pc remember that if you get the fan position wrong you would end up raising temperatures not lowering them.

anything further away than 5cm from the console amounts to heavy breathing and is basically ineffectual.

That is why i suggested lowering the ambient air temp using aircon.

I guess you could use a peltier device to lower the intake air temperature, but that might cost just as much as a cheap portable aircon device these days.

Connect multiple fans in series. I modded three cpu fans to work this way and my computer stays super cool even when I'm pushing it through a marathon gaming session. Oh it's also very quiet compared to running just the single fan.
