I'm thinking about affixing a duct running from my alpha to my inner psu exhaust fan. It is recommended you blow out with the alpha, and its blowing directly into the airflow line of my case exhaust fan. I prefer moving the air away from the heatsink because it brings a ton of fresh air directly over the motherboard, and it shows.
Does anyone have this hs? anyone tried reversing airflow or adding a duct? Here's some pics to show the case and where I want to set it up(keep in mind the height of the alpha)
All the way at the bottom

My main concern is that this is going to be about a 90º angle, followed by another 90º angle right after that. This could really impede airflow. Also, would it be advantageous to seal the other inner vent to make sure the cpu escapes the case? or would that overheat the psu?
...Another option is to duct the cpu to the case exhaust fan, and cut a blowhole at the top between the cdrom and the psu... but I'd like to avoid something where I could mess up the case.
ANY advice is appreciated.

I'm running a Celeron 2.0 with an Alpha heatsink. The airflow is provided by an 80mm rear case fan blowing directly on the Alpha using Zalman shroud off a Zalman 5700. Setup runs cool...cpu runs 4C over ambient at an idle.

You might notice a small fan sitting on the Alpha....it only turns on if the temp raises over 40C (almost never).
