Help me with my Fan layout

More informed individuals will respond. Listen to them!

I'm probably confused. it appears as if you have two fans mounted on the side of the case blowing air in and two exhausts. If those fans are indeed mounted that way it might work.

If they are internally hung fans that are merely forcing the air onto the board (memorya and ??) then that lower right fan should probably be an intake.

Except that I had one fan your picture is almost the same as my system. Mine had the top exhaust fan above the fan instead of below. When the fan in the lower right was turned around and converted from an intake to an exhaust it took 17 minutes before the beeping started. Luckily, I was in the room!
 
Well here is my take.

I have the two case fans, one for extra cooling on my PCI slots hence the fan in the lower left corner, the middle case fan is for overall cool air dispersal.

Then we have cpu fan blowing down, with a fan next to it blowing out to keep hot air from cpu getting cycled through the power supply making it even hotter.

The lower right fan is for pulling cool air across and hot air out of my hard drive bays, I have a raptor and a 160 gig down there. They give off alot of heat.

I have a fan port in the top of my case but do not want to mess up the air flow from my power supply. It sucks from behind and forward out of my case. If i had a top fan blowing it it would be recyling hot air from the back of my case and if it was sucking it would make the fan in the power supply work to hard to get air.
 
Well as only two are labeled case fan....the other is a sideways fan for the silencer. And the 120mm is mounted in the front of the case. Not on the door. It?s in front of the HD bay.
 
I'd reverse the 120 mm one so it'd cool the hd and some of the other heat could go to the video card....then the air would continue off to be sucked by the back fan. I dunno, test and check.
 
I was thinking that could be a possibility but i didnt want hot air circulating around my card and periphreals in my lower case. Then it might circulate to the cpu adding hot air to it.
 
From what I can see as to the pics, you have the 120 blowing out the front, 2 fans on the side blowing in, 1 on the back blowing out, and of course the supply blowing out, is this correct?
If that is correct, that is wrong.
Unless you have nowhere to get another fan blowing OUT the back, (which would be better), I would; Let the 120 in the front blow in, let the lower fan on the side blow in, let the higher fan on the side suck out, and leave the rear fan blowing out.
You need to remember that cooler air is Always lower, as hot air rises... Hope this helps.

I've always felt it was important to have good, single direction airflow. I'm not sure how much the side fans contribute, but I'd turn the front fan around. (agreeing with the people above) Your hard drives probably don't add noticable heat to the system. Yes, the raptor will run kinda hot, but nothing compared to the CPU.

Depending on how much air is being pushed by the front fan and the rear case fan, the side fans might not even be necessary. I guess it depends on how hot your overclock gets.
