Airflow is looking OK, but I assume you are going to put an exhaust 120 on the back and possibly 1-2 on top? You currently have a lot of positive flow, zero negative.
Remember that your airflow in over your rads will be slowed down quite a bit, so don't assume you need to match 1:1 on intake fans and exhaust. You'd rather have neutral airflow or negative flow, if possible.
thanks alot this post help me alot.
yeah I aiming for a low noise computer, I tested just fans and made sure they have low noise, they also push wery little air.
I will have 2 weak 500rpm one exhaust rear and one in top.
Currently the rear is intake but I think I will make it exhaust.http://i261.photobucket.com/albums/ii50/blundnec/th_648.jpghttp://i261.photobucket.com/albums/ii50/blundnec/th_6482airflow.jpg
