okay to answer the orginal question which is not asked but is implied.
"Why is the Fan on the side of the case blowing air against the flow of the cpu fan. "
answer is this.
the fan on the cpu rotates at a faster speed then the fans for the case air.
so in effect the cpu is punching through the air coming in from the side case fan.
or pushing its way bside the case fans output flow.
this can also be aproblem as it will tend to block most the air from the case fan getting to a direct flow route to the video and sound card's
how ever the extra air pressure does allow for some correction of the air being pushed away from the cards.
you by no means are locked in to this flow route.
you can make a little cone attach it to four posts. of which can be round ones or you can make them help with the airflow by being the shape of fins or wings.
but they need to beable to attach to the cone . and to the four corners of the case fan.
it should not stick in too far as that might press against some important part like the video card or the motherborad or the cpu.
which would be bad.
but the air flow correction hardware device does not have to be a cone it can be a flat wing with a bend in it if that is what you want it will direct the force to a route that is more of a direct route then the cone which is just to deflect it from hitting the cpu fan's out put.
the flat wing with a bend in it has a better chance of creating airflow all in one direction then the cone but both will work.
another way to make sure you have the best flow of air.
is to tape off with duct tape or use your soldiering gun and plug all the holes in the case bottom sides top and back. only use the holes in the lower front of the case and the exhaust fan for the power supply. that will asure you get only cool air from the side and the front and all hot air will go out the back.
for maximum cooling you can do all kinds of stuff like water cooling or high tech stuff. but a cheap way is to find the ac out let for your house room the computer is in. then take a flexiable hose no bigger in diamator then a vacume cleaner hose.
(if mom gets mad at you i did not tell you to use that hose)
but you tape it up to the ac grill for the room and hang the other end of it just in front of the case about 3 inches away from the case when you are using the computer turn on the ac so it is running the whole time the computer is on.
that will supply the computer with cold dry air. well if you have a whole house rehumidifer in your ac system then it wont be dry air. so move the hose to the 7 inch limit away from the front. and point it down not at the computer..
well it is a cheap way as in you not buying computer parts? but mom and dads electric bill will go up.

Proper Case Cooling Basics
I have one in the front((lit up blue, Yo!)), and one at the top((ALSO, lit up blue)). And then I have my CPU fan which I have a nob installed in the front of the case that allows me to controll the speed. I think I need more fans, DEFINETLY a HDD fan or two.
