Is this a PWM fan?

The "3 / 4" Pin connector under specifications got me a bit confused.

Can I use it as a PWM fan?

Do I need an adapter or something to make it PWM?

It's a 3 pin fan http://www.coolermaster.com/cooling/case-fan/megaflow-200-silent-fan/ so it's not a PWM fan. You can use it with 4pin header but have to sat BIOS to use voltage for speed adjustment.

The paranoid among us would say your confusion may be by design from the promotional info. What it REALLY means is that this is a 3-pin fan (Voltage Control Mode, aka DC Mode control only) that comes with an adapter so that, instead of plugging into a mobo fan header, you can connect it to a PSU 4-pin Molex power output. That latter option would get you NO ability to control fan speed, but it can be useful if you don't have a mobo header to use and want a full-speed fan. For use with your mobo's headers, look in its manual for details of the SYS_FAN or CHA_FAN headers. If it says those headers can be configured either for Voltage or DC mode OR for PWM mode, OR if the headers have only 3 pins, it can probably work for you. If you can't figure it out, tell us the mobo maker and exact model number, and we can advise.
