I'm in the process of updating my existing desktop, a blend of newer and older parts that currently lives in and around an Antec 1200 case I bought a few years ago. The case is great for airflow but difficult to work in, and sounds more or less like a jet engine. Having looked at a few possible replacement cases, I've tentatively decided on a Fractal Design Arc Midi, which I'm hoping will (among other things) be easier to work with (better cable and drive bay management) and perhaps dampen the sound a bit while still offering good airflow if properly configured.
Which leads to the following questions:
1. There are two front and one rear 140mm fan mounts on the Arc Midi. For these and the other slots where a 140mm fan can be used, any suggestions on a 140mm fan or fans that would combine long life, low noise and decent airflow? I don't necessarily need silent as the grave, and I certainly want to keep my CPU and GPU cool, but I'd really like to get away from the turbine effect I'm now experiencing. I'm willing to pay more if that's needed, though obviously I'd prefer a cheaper solution if I can get most of the same benefit while avoiding a price premium.
2. Should I use a different fan for the 140mm exhaust(s) vs the intakes, assuming I want positive or equal pressure?
3. The top slot on the Arc Midi can mount either (a) two 140mm fans (well, three actually, but I'm not planning to put more than two there initially) or (b) one 140mm and one 180mm fan. Should I go with a pair of 140mm fans or one 140mm and one 180mm fan? If the latter, any recommendations on a 180mm fan, with the same considerations in mind?
4. This is likely going to leave me with more fans than the native case controller can accommodate (it can handle three fans). That's a difference from the Antec, which includes a control switch or knob for each of the case fans. With that in mind, should I be looking at 4 pin/PWM fans only or is that not really an issue? Would it matter if I decide to get a fan controller? I assume not.
Alot of questions, but I'm currently lost in a sea of reviews and specs (some of questionable accuracy/veracity), and I'd therefore be very grateful for any feedback you might have to offer. Thanks in advance!
