Coolermaster Stacker side fan setup ideas

Ive just finished building up my new rig in a CmStacker 830 evo case which is currently relatively cool under normal usage (around 30-40 deg) and then jumps to high 50s when under load (batch processing large RAWs in this case). Thats all good and well but currently Im only using 3 120mm fans (2 intake in the front and one exhaust at the back) when I have room for another 3 as well as three 120 fans for that very purpose.
I was just wondering if anyone had any ideas on how the remaining fans should be set up?
For anyone not familiar with the stacker it comes with a removable 4 slot fan bracket/door, 2 slots at the top and 2 at the bottom. The 2 up top sit in front of my HSFs (im running a dual cpu system) and as such I cant use the top left slot as there isnt enough space between the HSF and the fan. That leaves me with one slot on the top right (just to the right of my second HSF) and 2 on the bottom.
I was thinking of having the top as intake and the bottom as exhaust, simply because it would be blowing cool(er) air towards the processors. That having been said, heat rises so I really dont know what the most sensible option would be :confused:
Also, does anyone know if 3DMark runs on vista 64, and if not can someone point me in the direction of a suitable benchmark program that does?
Thanks

heat rises... you'd want an exhaust at the top to pull all the warm air out.

Bottom/sides in, back/top out to get the warm air out asap.

That's the way I had it anyway back in the day when it mattered!

In a lot of cases side fans don't make much improvement in a case which already has good airflow. They blow against the mobo and can create a lot of turbulant air. In my Antec900 i actually found poorer results by installing a side fan, whether it was blowing or sucking (it seriously did suck). My suggestion is to try to create a high pressure area and the front bottom of the board, and low pressure at the top back. Of course, if you have a lot of HDDs in the case then the only really good way to generate airflow is using side fans as intakes. If you do have to use side fans as intakes then put them at the base. Especially if you have a cpu cooler that blows from front to back (like many of the high end designs).
