This thread inspired/reminded me to do some more testing with my own setup once I change my CPU cooling.

PSU fan never really turns on or if it does I never hear it. I have a voltage selector on my case for the fans connected to it (two front and top) and I run them at 7V 12 V is louder. I perhaps should try it as exhaust though, since I have positive air pressure (I refer this for dust cleaning reasons), and it might help slightly with temperatures (namely GPU temperatures if nothing else). My side intake is empty, as having a fan there as intake did little to nothing to temperatures, so it was added noise and dust. Granted, that was with my old CPU and it had a tower style heatsink, and since I changed my platform, I'm on the stock (not a tower style) right now so it could have changed, but I'm changing back to a tower style cooler very soon anyway. I tried the top fan both ways and it wasn't much different, but top as intake gave me the slightly lower results, likely as it brought fresh air in directly in front of the CPU. Reason being the front two intake are obstructed by many hard drives in the way. Top fan as intake isn't always necessarily unorthodox I have mine that way at the moment (I don't have the same case as the OP). Changing just one thing could change things.

As always, experimenting yourself and collecting results will give you the best answer though. and rear and (if applicable) top as exhaust seems standard as a baseline, and often gives good if not best results. Usually, front and (if applicable) the bottom as intake. This should provide you enough airflow you'll need.

#BEST FAN SETUP FOR CORSAIR 4000D AIRFLOW PC#
I hope everyone is doing well, I recently upgraded my pc case to a Corsair 4000D Airflow and was wondering the best fan configuration for my build, I have a Noctua NH-U12A CPU cooler with a total of 5 Noctua NF-A12x25 PWM Fans in total (1 on the back with the fan towards the back, 1 on the CPU cooler facing towards the front of the case and 3 on the front of the case facing towards the front) any suggestions would be great and I know there might be the possibility that I have the best fan configuration already, but I'm curious if there're any other configurations I haven't thought of, thanks in advance.
