Stupid question about intake/exit case fan

I'm building my PC and am going to have 3 intake fans, 2 120mm in front 1 140mm on side. and 3 120mm exit fans, 2 on top 1 in back. My question is because I haven't fired it up yet cause I'm waiting on the processor and GPU, which way do the fans face for intake/exit?


Is this fan going to blowing air "towards" you if looking at it or sucking the air away from you?

Sorry if it doesn't make sense if I need to elaborate let me know! I feel dumb for asking this but I wanna make sure I got em right before I fire it up. Haven't built a PC in about 8 years >.< thanks!!

    That will suck air away from you.

    A general rule is the air will blow out the direction the concave side of the fins point.
  2. Yes ^^ C _ for -
    Also --
    Here it is- Lower fans [bottom] they should be installed as to inhale air as air in the bottom is cold , as for upper, they should exhale, as upper part contains hot air. Hope it helps
  3. Cold/in/front/bottom

    Exhaust/out/back/top

  5. ... Almost every fan has two arrows on the side frame showing the direction of blade rotation and the direction of air flow...

    They're subtle, but they should be there I would think.
