I finnaly found time to finish off the holes for the fans I wanted to put in, so far I have had some interesting results....
these are only rough tests and I will post more conclusive results when they are available.
Firstly the 120mm side case fan blowing down onto the intel HSF seems to have reduced temps by a few degrees C, I made up a cardboard surround to duct the air more directly over the CPU (finishing close to the CPU fan) to my suprise the temps actually went up and the air flow through the case seemed to drop.
I also put a 120mm fan in the back above the mobo but below the PSU and have it blowing in and a 120mm fan in the front of the case down the bottom blowing out, to my suprise again the airflow through the case increased but the temps never moved...
as I said it's early days but at this point in time it seems cooler with 1 fan rather than 3 (plus the PSU fan)

Sunny Florida, you can keep the midwest!!
You are attempting this bassackwards. Heat rises, why have the fan sucking out at the lowest point. The other fan pushing in is just blowing air around the case.

I have my reasons for going from back to front, I am planning to use the air comming out of the case at the front for air flow through fins on a cooler, besides the amount of air flow going through the case will take care of any little amount of heat that rises
