  1. Depends on the fans. Just saying 120mm or 140mm is not really any information.

  3. you have the choice for 120 mm or 140 mm but made shure that the cfm from input with match the one from the output for a same scale air flow .

    man it depends on the speed and the blades.
    x3 120 at 2500 rpm performs better than x2 140 2000 rpm bc its just 20mm
    there are some 3000 rpm 120 fans that can out perform a 2500 fan
    also it depends on the radiation area so 3 can take place more than 2.
    dont forget to put intake fans also.

    Still depends on the exact fans .
    I would just keep the 2x 140mm fans that come with it.

    List the fans.

    Different fans are going to have different CFM even if they are running the same speed.
