3x 120mm fans or 3x 140mm fans?

I'm building a PC soon, and currently have this build: http://au.pcpartpicker.com/p/fVy3K8
I originally intended to install 3x NF-F12s in the front and 3 140mm fans on the rad and rear.
However, i've noticed that the front can hold 3 140mm fans.
My question is whether the optical drives will block any airflow if I install 3x 140mm fans, or whether there is no difference between installing the 3x 140mm and 3x120mms.

Edit: Also on a side note, is it worth getting the WD Black 1tb or should I opt for the cheaper blue? Thnx.

  1. You need to post the permalink so we can see the build, but depending on the fan two 140mm fans will outperform 3 120mm fans.

    Oh sorry lol, thought i'd published it :) updated now
  3. Given your build, I think two 140mm intake fans would do perfectly well.

    Nooonoononono, I said that the front panel can mount EITHER 3x140mm or 3x120mm, and I was wondering which would be better (Getting NF-A14 PWM)
  5. Best answer
    (It can also mount just two)
    Between the two choices the 140mm option would move more air while being quieter (Larger fans, lower RPM) compared to 120mm

    Cool, thanks!
  7. Nice build! I have the fans you're looking at. They're sufficiently quiet you can run them flat out and they're barely audible. The 140s move good air and the 120s decent air. I wouldn't worry about air blockage. Get as much in as you can(preferably filtered!).
    I'd buy the blue, there's not a performance difference, just a warranty and possibly(HDs die, that's a fact, just it's a question of when) time span difference.

    I swear that the mastercase pro 5 allowed you to install 3 140mm fans in the front without compromise, could you double check this? I'm not sure :P
  9. I dont think you get what I mean.
    The case supports up to 3 140mm fans in the front. You can always put in less if you dont need them.

    If you put in 3, does it eliminate the possibility of installing optical drives?
  11. ohhhh, one moment
  12. Theres no solid information, but by looks alone it may block it. Im not 100% sure.

    That's what i'm wondering... there's probably a seperate bracket for fans, but idk. Some cases are weird, and coolermaster is probably one of those brands that do strange shit with their products :P
  14. either or, you're saying? lol
    Could always go with an external USB DVD drive.

    I guess, i'll probably just yolo it since the site says so, I can always RMA on false advertisement if I can't fit 3x 140mm :P
