    Do they intake from the sticker side ?

    I have this fan , whats the direction of airflow on this ?


    Also whats the airflow in cfm on the default case fans on this case ?

    What relatively quiet high cfm fans should i upgrade to ?

    Needed 1 92mm , 1 120mm , 1 140mm fan .

    Already have this, how good is this ?

    well if you are looking right at that package the air is going in that way and out the other side.

    the sticker side with the amp ratings and etc.. is the side air flow.

    What you want is high CFM (flow) and low DBA (noise)

    Radioshack is having a super clearance on Thermaltake stuff i bought a bunch of their 120mm fans and misc stuff. They sold out online but you can find them in their store if you have them in your town.

    then just go to type on the side PC case fans.

    is it hooked up to the MB ? what's the RPM it is running ?

    the side with the structural plastic brackets is the side the air would come out.

    the side opposite to the sticker is where the air will be coming out of ?

    most fans blow the direction the stickers are on them (stickers facing out) to the back exhaust fan and stickers facing in as a intake fan.

    If you look on the sides of your fan there should be an arrow pointing in the direction of air flow and also rotation of the fan blades

    as for quite high CFM fans SilenX has the most quiet with 18dbA and 90CMF but at a cost of $20 for 120mm

    take a look at some of the Antec line of fans they have a small lil switch to adjust the speed and are fairly quiet with good CFM.

    Usually fans that have a CFM of 90+ are running around 2k rpm and have a 40dbA reading which is very noticeable if you have more then 2
