    Hi,
    my pc case is NZXT Gamma .It has 6 fan slots
    one NZXT stock fan with 45cfm
    I am planning to fix fans in other 5 slots .
    I am planning to fix

    2 x silverstone 120mm 110cfm fans in side panel
    1 x silverstone 120mm 110 cfm fan in front
    1 x amigo 120mm 70cfm fan in rear
    1 x stock nzxt fan with 45 cfm in top
    1 x zigmatek 61cfm fan in top

    I am not planning to use any fan controller

    total intake =front+sidepanel=110+2 x 110=330 cfm
    total exhaust=rear+top=70+45+60=175cfm

    is this a good setup
    If not plz suggest me some changes
    Experts PLZ help :banghead:

    Noisy, but it will work. The exhaust fans are going to be pushed harder than they should be, but nothing crazy. It's not rocket science. Just put them in the way you think they'll work and they probablly will.

    If I told u.. I'd have to kill u
    Its going to be a wind tunnel but will work fine. You will have some positive pressure in your case but some is not bad. The exhaust on the back and on the top will keep the positive pressure to a minimum. Its always smart to have more inlet air compared to exhaust for proper air exchange and to keep static pressure on your fan motors to a minimum. I run 3 120mm inlets with 2 120mm exhaust and I have a custom vent on the top because warm air rises. You also have to count the psu fan as an exhaust also. :toast:

    Computer fans will not be able to create pressure so great it will damage anything. No chance at all.

    Plus the case would have to be sealed tight, otherwise, air will just go out through some small holes.

    I have lots of fans pushing air in and only 1 fan pushing air out. No problem at all.

    yes on noise, no on damage. Unless you count dust.

    make the top and rear the exhausts. Other than that, ahem, go with the flow.

    The fans won't damage anything.

    Check online for actual fan tests before trusting manufacturer-provided CFM numbers.

    There's plenty of debate online regarding negative vs positive air pressure. Keeping it as close to neutral as possible is generally best.

    Once you get the fans, I'd recommend moving them around a bit to see what works best with your exact setup. Although chances are, it's not going to make so much as 2*C difference.

    note:

    By plugging the fans into the psu they are going to run at full speed. It you want you can plug some into your motherboard (if extra 3pins are available) and control the speed through software.
