Hi, I am having some trouble understanding optimal case fan setup for an air cooled system. I have been reading around but different accounts conflict with one another. Specifically, some accounts say that using a top forward case fan reduces temps while others say that it increases temps.
Mounting points for for my H400 case are:
2x 120mm/140mm front
2x 120mm/140mm top
1x 120mm rear
I understand that front/bottom are generally best for intake and top/rear are generally best for exhaust. However, the case is fairly small and has no drive cage so it seems that some intake air will be exhausted by the forward top case fan before it has a chance to cool anything. This mount point seems more for an AIO/radiator setup.
My cpu will be air cooled and I don’t want to use a setup that directs intake air away from components. Right now, I have 2x 140mm intake and 3x 120mm exhaust but I am waiting on a few more components before I can start the build. I was considering changing the top exhausts to 140mm to help with noise.
Anyone happen to know if that forward top fan is a hindrance? If so, any ideas on how to balance my airflow without just reducing rpm on the intakes?
Many thanks for any help!
