Computer case fans question

[salawow]

Hello ! (english is not my native language, sorry)

I have a Xigmatek Mach case (do yourself a favor a never buy that, it's really cheap). It has 3 preinstalled fans with possibility of 2 more on the side panel. It happen that i have 2 spare fan lying in a corner, so i thought i'd put them in my case. However, i know nothing about airflow, and i don't even know if it's a good idea to install both of them.

At the momment, there is:
a 120mm intake fan on the front bottom
a 120mm exaust fan on top
a 120mm exaust fan on back (top back)

The 2 slots for extra 120mm fans are on the side panel, one on top of the other. If i put my 2 fans there (exaust), the only intake will be from the front bottom fan, and from some little holes in the top, beside the top exaust fan.

What should i do ?

Thanks !

Side panel fans are not needed most of the time.

you want a positive pressure in your case so add another intake fan anyway. (front or side panel?)

Would it still be slightly better than nothing ? (since i have the fans in my desk anyway)

@tsuneo6

The only slots for extra fans are on the side panel. So you suggest i should put them on intake instead of exaust ?

 

[tsuneo6]

on the sidepanel you should put an intake fan. you want to have more air going in then out. it will result in better cooling and less dust intake.(you may want to put a dust filter on the bottom intake fan though)

Ok, so since i have 2 extra fans, i should put both of them on side panel at intake ?

 

[tsuneo6]

if you have them, why not?
