Nah, transporting the heat to the edge wasn't made up.  

  However, while that may decrease fan speeds on the case fans, you added two more fans.  

  Nothing's free, as they say.  I mentioned have the heat exchanger in the case because you actually don't decrease the amount of heat in the case - but you have more effectively moved a lot of it towards the edge of the case near the room air.  I just don't know how much heat that processor gives off...and I'm too lazy to look it up.
