140mm Case fan with/without PWM?

I'm trying to pin down the quietest, highest air flow 140mm, 4 pin (PWM) fan.

I really like the look of Cougar HDB's. Noctua is always everyone's first choice. Then there's also Phanteks.. Xigmatek?...

I currently have some cheapo 3 pins in my case, and a sabertooth z87. They seem to be controlled by the board anyway, I just don't like them... So I'm confused what I'm really looking for. 3 or 4 pin?

Thank you in advance

    That mobo has excellent onboard fan options, besides CPU fans:
    4 x Chassis Fan connector(s) (4 x 4 -pin)
    2 x Assistant Fan connector(s) (2 x 3 -pin)

    So stick with 4 pin PWM, unless they're all full. Can't go wrong with the names you mentioned, here are a couple more to muddy the water:

    That last one, the Prolimatech, is super quiet while moving huge amounts of air. Looks excellent.

    But also keep in mind, even if it's a 3-pin, you can often can control them through the BIOS by setting up some automatic fan curves.

    EDIT: added a couple more
  2. Not all three-pin fan headers are created equal. Some do not support voltage regulation. Your board pretty much has only 4-pin slots, and I am pretty sure that all of them support voltage regulation.

    Anyway, PWM depends on a type of "on/off" signal to operate the fan speeds, but it is fed the constant 12V.

    I like Cougar fans a lot, but I wouldn't trust any PWM variants. Xigmatek seems to be hit or miss.
  3. Thanks for the input guys.

    Yeah, I sealed off my case (Ostrog Gt) everywhere. Top bottom. Taped off all the nooks and crannies. Positive pressure, exhausting past the Zalman Reserator 3, out the back. I was gonna put in an exhaust fan, but it's not necessary. Positive pressure, and it's extremely quiet already. I'm eyeballing those Cougar HDB's, awfully hard. The assistant fans on the Sabertooth are kinda noisy, but not necessary. So I unplugged them. They're 35mm sleeve bearings.
  4. Wow. Never thought Rosewill would make something like that
