Hello,

More or less worried about how to do the top fans.

Leave them as is.

Basic airflow - In the front, Out the top/back.

Two small hints.

1. For the two top exhaust fans, place them in the two rear-most locations at the top, and none at the front top location. A fan at the front top will just suck out all the air coming in from the front top fan.

2. Because the dust filters in front of the three front intake fans reduce their air flow slightly, this arrangement likely will result in a small interior vacuum pressure in the case. That can allow unfiltered air to enter the case at any leak point, whereas it is better to have a slight positive pressure to reduce dust intake. So arrange the connections of your fans so the three at front are controlled by one header, and the top two plus the rear are controlled by another. AFTER you have your system built and running, you can go into BIOS Setup and adjust the header for the three exhaust fans to make them run a little slower than the front ones. That can give you the right air pressure balance. If you want details on this, post back here:
