Carbide 500R Fan Setup (Help, please, first time builder)

The current set up for my Carbide 500R is...
Two 120mm front bottom, intake
One 200mm side (bottom-ish), intake
One 120mm back top, exhaust

I know the general rule is side + front = intake, and back + top = exhaust. Other than that, I know jack-diddly-squat. Just looking for the most efficient set-up.

So...

(1) Do I need to buy additional fans?
(2) How do I properly measure CFM to understand the flow of air?
(3) Since the case has holes all around, would it be better to create positive air pressure or negative air pressure?


I have not fully put together my first system (I will be doing it this saturday), so I do not have any heat metrics to share.

  1. You don't need to measure nothing , look at the specs of the fans ( CFM ) and do a simple math. Your intake is huge , in your place ill put 2 more fans on top for a better outake.And if you have fan controller put the side fan to a slower rotation.
  2. @sosofm, thanks, I appreciate your advice, but the Carbide 500R doesn't indicate the CFM of the fans. I've checked. I've also tried searching for that information online, and the only thing I was able to pick up from information floating around is that the stock fans actually aren't very good. I've heard it from a few different sources, but I don't know how true those statements really are.

    For some stupid reason, Corsair decided not to disclose the fan specs other than size, and that they are equipped with LEDs.

    Edit: *facepalm*

    I just came across this on corsair forums :

    Front 120mm x 25mm
    RPM - 1200
    CFM - 43.2
    dBA - 18
    Static pressure - 1.6mm H2O
    Power - 1.2 Watts

    Rear 120mm x 25mm
    RPM - 1200
    CFM - 43.2
    dBA - 18
    Static pressure - 1.7 mm H2O

    Power - 2.16 Watts

    Seems like the source is credible. I will continue to look for information about the side 200mm fan. If anyone knows that off-hand, I would really appreciate it.
  3. That is not such a big problem if you put the side fan to a lower speed and add 2 more fans on top of the case , if you do this you will have good air flow and good case cooling.

    Don't foget that your PSU will also act as an exhaust. To answer your specific questions:
    1. I wouldn't buy any additional fans unless you get high temps using the front/side intake and rear/top exhaust setup.
    2. You don't need to measure CFM...and wouldn't want to spend the cash to get the proper tools to do that. Simply monitor temps for your CPU/GPU. Your good to go as long as they aren't excessive at load. You can test this using CPUID to monitor hardware and running a stress test program like PCmark.
    3. Again...stress test and monitor...don't overthink this!
