Hello, I have two pictures here for you, the 2nd of which is what I was thinking I could perhaps do for my fans?

I dont have the side intake fans, but my main question was:

If i switched the first of the two top fans from exhaust to intake, would that not help cool the system (mainly overclocked gpu and cpu) a little more?

It seems like on the right side of the 3rd party cpu fan (where the intake part of it is, and above the gpu) it would create a little cooler vortext area, where the cases and the gpu's heat would rise to, the fan would try to cool that area, and the cpu intake fan would then take that and push it out the top and back fans.

Am I crazy for thinking this? I am thinking about this mainly for gpu cooling purposes. In the end all the air still goes towards the back left of the case and goes out.

This is the normal way:

This is the way I am thinking of. (don't have side fans, and sorry bout the blue, hard to see)

Solution
It could do, you can always run a test like prime95 and record the temps then turn that fan around.

The only danger I can see is that you push hot air down towards the GPU
General rule is Top and rear out and everything else in.

Modify that rule when you have more out than in.... ya wanna make sure that the rear grille is exhausting air.

Modify that rule when ya have radiators, these ALWAYS blow in no matter where they are.

Of you are overclocking a Haswell CPU under adaptive voltage, please don't use P95. Intel XTU, or better yet RoG Real Bench will be safer.
