Hello to everyone in the community

I am opening a new thread (I thought that it would be better to create it, instead of writing in an older thread of the same matter, since that thread received an answer as a solution), to describe better my case.

I have recently built a PC in this Corsair 400R PC case, with the following configuration:
- PSU: Etasis ET750 750W Gaming.
- Motherboard: Asus P5Q Pro Turbo.
- CPU: Intel Xeon X5482.
- CPU Cooling: Corsair Hydro H100i v2 Liquid Cooler, with its Intel Mounting Bracket specially modified to adapt to socket 775 holes.
- RAM: 4 x DDR2 OCZ Platinum Dual Channel Kit OCZ2P10664GK, total 8GB.
- RAM Cooling: Corsair Vengeance Airflow.
- GPU: MSI Radeon R9 270 Gaming 2G 912-V305-001.
- System Disc: SSD 256GB ADATA Premier Pro SP900.
- Storage Discs: 3 HDDs
- Optical Drives:
(A) Pioneer BDC-S02BK BD-ROM/DVD-R-RW SATA Drive.
(B) LG GSA-H50L DVD-R/RW IDE Drive.
- Expansion Cards:
(A) 1 x AverMedia AverTV Capture HD727.
(B) 1 x PCI-E to 4 x USB 3.0 Card.

Please, observe the following photo:

At this moment, I have configured the fans airflow as follows, as you can see from above photo:
1) The Corsair CPU Cooler Fans are blowing air into the case (recommended by Corsair).
2) The front lower fans of the 400R are also blowing air into the case.
3) The back fan is set as exhaust fan (blowing air from the case internal to the environment)
4) The Etasis PSU fan is sucking air from the case internal and it is blowing out to the environment.

(The yellow arrows show the airflow direction of the case fans and the PSU fan. The smaller orange arrows show the GPU fans airflow direction. The RAM cooler fan is blowing air directly on the RAM DIMMs. There is no arrow for the RAM cooler fan in the picture.).

However, I still have to configure the side panel fan or fans. This case can accept two more fans at its side panel, 120mm or 140mm each. At this moment, I am thinking to put only one 120mm fan at its lower position and set it as an intake (blowing in) fan, to provide an air stream for the GPU (the lower position is closer to the GPU than the top one). I am thinking to let the top position free, without any fan at it or - alternatively - to put a fan, operating as exhaust (blowing out). I am also thinking to operate this PC with a moderate overclocking on the CPU and RAM.

In my mind the second solution (lower side panel fan "IN" - top side panel fan "OUT") seems better, since it provides a higher cooling flow to the PC internals, but I am not so sure about it.

I would appreciate your suggestions.

Thanks.

For your information, and after thinking as an engineer (I am a marine engineer, anyway), I considered the following setup for the side fans of the case.

The lower fan is blowing air in the case, almost directly on the GPU, while the upper fan is taking air out of the case, thus making total air flow more "balanced" in the case internals.

So far, this seems to work fine and it keeps temperatures low enough of all components.
