Question Top fan configuration thoughts

[knght990]

I currently have a Cooler Master 690, circa, 2008-ish? I'm switching to a Meshify 2 for a new build.

The CM690 has one bottom fan, one front, two top, one rear and two side. I configured the front, bottom and one side fan over the gpu as intake. The rear is exhaust. The top fans, I configured one as intake in front of the cpu cooler and the other as exhaust behind the cpu cooler. All are 120mm.

As I'm planning fans for the new case, I wonder what your thoughts are about splitting the flow direction of the top case fans.

Bad idea. You will set up an airflow-loop between the fans that will reduce overall performance. You want the overall flow in the case to be in one general flow from in to out front to back without loops. Only put a top exhaust fan behind the cooler and seal the mount in front of it. Two fans in the front, one in the rear. Nothing in the bottom if there's a mount.

CM690 is from a different era. By today's standards, its fan mount options are a bit of a mess and the overall design isn't very good. I wouldn't use it as a reference point.
