The diagram is tripping me a bit because I'm not sure where the mobo is. Case model? But I would say yeah, better to have more intake in this situation.So, I'm not the greatest at figuring out airflow... As I understand it, the fans that came in my case (bottom front, and top back) were the ideal setup when it was just them. I recently installed a a 240mm radiator/fan combo as part of an AIO liquid cooler. Now there are 3 output fans (2 as part of the AIO at the top of the case and the one in back) and one input (the single front bottom fan, see crappy illustration below).
The AIO runs great, even with my CPU overclocked I never hit over 65 on the CPU itself and the liquid hasn't peaked above 45ish... but I live in Arizona, and it's going to get a lot hotter.
So yeah, given the added fans pushing at the bottom, is this still an okay-to-ideal setup? Or should I move the back fan from exhaust and move it to the front as an intake to have a 2-2 intake/outtake?
(Just realized I didn't fully label the green lines, that's where the vents are in the case for the intake).
Just make sure air flows over components that are not actively cooled, like RAM and the Board itself, and that air still flows towards the GPU.
