Best possible airflow?

[King3x]

I wanted to utilize all my case fans so I get best possible airflow.

I want this because my GPU temperature is a little high, when playing games mid 70s and I even saw it at 80C once!

How can I utilize best possible airflow?



I didn't want to make it too wide, so the one on top is my back and the top is where it is.

I have two fans in PSU, one southbridge chipset and the rest standard.

The one on the back, though small, is probably my most powerful fan, contributing to the most noise in my case.

The two on the side use to be exhaust, but my brother advised me to flip it so 4 in one out (temperatures taken from old build but so far, I see no difference)

EDIT : It seems I've left out a very important piece of the puzzle. I have a 7800GT (XFX 256MB 450/1050). The back and front are pretty much set so I just need help with the side.

Also, if anyone knows of a program that can be used to record temperatures that would be great. I know that there are programs and the nvidia control panel that can tell me the temperature, but I heard it goes down like crazy immediately after you shut it down, so just to make sure that really is the highest it goes.

If anyone can verify or supply a link that would be great.
