fan configuration

I have my cpu fan, and 5 fans around my pc:

3 IN fans: back bottom and front

2 out fans: top

I have the 2 top fans and the bottom fan on a controller, which was more something I wanted to do than needed, I'm not overclocking or anything like that at this point, if anything I felt like I wanted my gpu to be cooler, it idles at like 51-54 C. Anyway, the fans even up all the way, don't really make a difference, but I was wondering if that setup was reasonable. The top two fans are covered with a mesh that came with my case, I was wondering if I should still have that on, even if those fans are blowing out. I was considering flowing air in through the top also, but I thought maybe that mesh would make the air flow less in that case.

this is my case:

Here is a drawing I quick whipped up for my case.

Blue is IN fans

Red is OUT fans

The thin red arrow is my GPU exhause (I think it is out the back)

The thin red rectangle is my psu fan, which I did not know worked as an exhaust until now. I thought my psu was solid on the bottom, in fact I kind of still think it is, but I should have a look when I get home.

Notes: all designated fan spaces on my case are covered in fans, so that's where those are located. There might be enough room in between the fan speed controller and the bottom fan for another fan if I rigged it, but I don't think it is meant for a fan, and it might take away all or all but 1 of my remaining bays to put a 120 mm fan there. And I would have to order another fan.

The only fan with a dust filter on it is the bottom fan next to the psu, as it is on carpet.

the gpu fan is on the lower side, and the board is on top in the pic



Looking at this now, it seems dumb, but how would you guys suggest doing it, keeping in mind that another fan could be an option. My GPU idles around 55 C, my cpu around 39 or 40 C, and my system temp around 44 C.
 
It's as simple as Front (Bottom) = In (though I try to stay away from bottom-fed air), and Rear (Top) = Out. Your setup as it stands now is creating a lot of turbulent air inside the case and preventing it from flowing properly. I would get rid of your rear intake and make it an exhaust, and probably remove one of the top exhausts as well. Also, if you remove the lower intake you won't be hurting anything. The pictures on Newegg were a bit vague, but if possible, I would put another intake fan above the one you already have on the front.

Don't screw with what works; anything else will most-likely either provide a non-noticeable decrease or perhaps even increase internal temps due to the lack of proper smooth airflow.
 
Either spin the rear intake round and use it as an exhaust or put it on the front of the case as an intake. I'd go with the first idea in an attempt to create negative pressure inside the case.

What GPU are you running?
