Most fans hav an air flow indicator on the outside with a directional arrow.
If there is no arrow, the hub side is the intake side... pic #2 that is the hub side of the fan blades of wich the air would be drawn in.
Hope that helps

so on pic 2, air is being drawn in, thankyou.
would you rearange any of the fans for better air flow?

The side fan should be an intake fan, flip it.
The rear grills look very restrictive, think about cutting them out.

Also, you can tell by looking at the shape of the blade. The fan will always blow air in the direction of the concave blade side and pull it from the convex side. Another way is to simply turn the fan on and see which way the air blows

good luck

first of all. cable menagement is always good for increasing airflow. you wanna make it so that it's not cluttered. check out the rate my cables thread for some idea of what to do. As for the fans and the orientation of them, Think of a fan as a corkscrew scoop. it scoops the air and puches it downward. You usually have the front-most fans taking in the air and the back fans and top fans used for exhaust. You also wanna try to have 50% of the fans for intake and 50% for exhaust or there might be a slight vacuum or pressure
(nothing bad though).

Any other questions?

thanks for help. so i should flip the side fan so air blows inwards? it is blowing inwards right?

 

[dominique120]

here are some pics the side fans blow air in

The pic shows that it is already blowing out.

 

[The Duke]

the common basic is in the bottom/front out the top/rear.
But the oddity in your case, those foreward/top would likely be intakes.

 

[dominique120]

in this pic you can understand better

Try reading this.

Fire up your rig and feel. Or use a tissue or whatever and hold it in front of the fanblades on both sides.

*edit* dominique120: Not all cases have the same configuration.

Best way to tell What direction your fan is blowing saying its already installed is to use a piece of paper to see if is suck to the fan or blows away from it.

Dremel out the grilles on your case. You'll double the air that fan is able to push through there, easily. None of your fans can run at their rated capacity because those grilles block things off...and they provide a nice place for dust to 100% block your fans.

From those pics all five fans are blowing air out. From my understanding turbulent air flow gives better cooling (although noisier) than laminar. With all fans extracting you get more laminar airflow inside case. (You get laminar air flow in front of fans and turbulent air behind) As said before flipping the side fan to blow in might help by setting up turbulance.

Also is there no front case fan probably infront of the hdd's, that should definatly be blowing in?

Cabeling does seem restrictive beside cpu especially with side fan extracting you are losing a lot of cold air there. I'd definatly try changing the top fans to intake aswell with thier position on you case. Its worth a test run and see how your temps go.

And as kimosabi said test using a sheet of paper and experiment with what works best.

i agree. that's probably your biggest issue right now. i clipped out the intake grills on my 300 for a similar reason.

I did the same think on my Raidmax Smilidon and there is much more airflow and less noise. Your case's fan grills look to be extra restricting. In picture 1, you are going to want to turn around the fan on the case door. You want the air to be pushing in, not pushing out.

 

[BradleyW]

so the top side fan needs to blow in and the side fan needs to blow in. the bottom side fan blows out and the two top blow out?

should i don that and test it.

 

[BradleyW]

a lot of hot air comes out of the two fans at the side back area, should i just flip the side fan to blow in?
