To give it a chance you would need to divide between the fronts of the heatsinks so that there are two halves. The left side drawing in cool air for the gpu, hot air out the back and the right side drawing cool air thru a cutout for the 120mm fan, exhausting hot air from the cpu out the right hand side grill.
So far its been running like this for a few weeks and the exhaust air from the rear fans is slightly warm. What you say above is something I have already considered but as you say, I cant really see what effect its having properly without taking some temp readings. This is a work in progress and when I get temp testing equipment I will experiment with some other ideas I have.
I have tested airflow with cigarette smoke. The air drawn in from the 120mm fan does exit from the right side grille and also from the front vent under the DVD drive. Its basically pushing more CFM than the rear fans are pulling - through the main GPU sink. Thats not to say the exhausted air isnt being drawn into the GPU though. Obviously some of it is.
Extending the GPU shroud out to the front of the case, and cutting out the right hand side grille will more than likely reduce temps further.
Thanks for your input
EDIT: Maybe reversing the 120mm fan will help. I'll try it when I can take some readings.This post has been edited by mikesnowdon: Feb 5 2012, 02:01 AM
