Can't keep system cool

[galey]

Hi just built a new system which I can't keep cool.

I have a fx 8350 NOT OC ( standard settings ) running a GTX780 GPU
I have good airflow 2 intakes in front 120mm of case 1 in bottom and 1 in side both 140mm and a 140mm exhaust top rear plus exhaust tray on top of case.
Using a Noctua CPU cooler
It's idle temp is 40c and mainly runs in 50 -55c range however running games like crysis3, COD ghosts,batman arkhams it blows out to 67c as soon as you get out of the games it cools down again.

I was hoping to OC ( reason I went with AMD ) I'm starting to have second thoughts )
I'll post case pics when I get home from work ( where I em now )

Any advice welcome.
Thx

I think it is partial not having good airflow. From front and side are "mixing" with eachother and then the back/top is not blowing ideally, maybe. Does having the case open help at all with temps?

And is 67c an actual case temp or cpu temp?

67 is cpu temp. I have tried re-applying thermal paste re- configure case for better airflow.
Took side of case of which did lower temps a little.

Swap one of the case fans to a Delta. As you found out, those cheap fans don't work well enough for a modern high performance machine.
