Best Airflow for my System

Before I get started this is my current set up in relation with airflow:
Intake:
Front 140mm intake fan
2x120mm side panel intake fans.
1x120mm bottom intake fan

Exhaust:
Antec Kuhler 920 Push Pull config.
1x140mm top fan
1x80mm (squeezed in) second top fan

Now all seems good overall, good stable temps never going above 45-50 degrees when prime95 is running for extended periods of time.

However when gaming, sometimes the fans become abit too loud for my liking, the inner ambient can go up to as much as 36degrees, (however it is hot at this time of the year in the UK). I find there is good airflow in my case except for around the CPU pump which tends to be abit warmer. Im considering switching my top fan round to provide that cooler air which can then be exhausted by the Antec 920, however I don't know if this is a good idea as it may mess with the airflow from the two side fans. Any reccomendations?


Full system specs:
GA-990FXA-UD5 Mobo (OC'ed NB @ 2600 stable)
AMD FX8350 BE @ Stock for now
16GB DDR3 Corsair Vengeance @1600MHZ
1TB Samsung Evo SSD
1TB SSHD
2xGigabyte R9 280x O'ced Edition (Crossfired)

NO DON'T your airflow is set up exactly right - you have more air being drawn in than expelled, creating pressure in the case, which helps the Kuhler do it's job. If you turn the top fans round, you are then working against physics, as hot air rises - top vents should ONLY be exhaust fans.

Really, you have a very good setup - I wouldn't mess with it.

If it's getting too loud, investigate quieter fans

Me? Corsair Vengeance C70 - which is noisy. Also a Fractal Define R3, which is much quieter, but has less room inside - the R4 is probably a better bet

Thanks dude, I'm using Corsair fans, always do as their much more quiet than some of the others, I presume it must be due to this crazy weather over here right now, at the mo my ambient temp is 28 degrees, used to be down at 19. Cant seem to find a definitive answer for safe inner system temperatures.... :/
