So, I've got this setup:

What is PWM and how would it affect those fans? There's a built in 5 slot fan hub thing in the Phanteks that allows the Mobo to control all 5 depending on heat, does that mean that those fans have to be PWM?

PWM stands for Pulse Width Modulation and it pretty much varies the fan speeds so they're quieter at lower temps.

so, many fans only have 3 pins.  PWM(pulse-width modulation) fans, have a fourth pin that allows you to easily change the speed that the fan spinning. 

the fans dont have to be pwm fans to plug into it, however i think for it to work properly, they have have to be.(although i could be wrong here)

It does not....

Pulse width modulation (PWM) is a fancy term for describing a type of digital signal. Pulse width modulation is used in a variety of applications including sophisticated control circuitry. A common way we use them here at SparkFun is to control dimming of RGB LEDs or to control the direction of a servo motor.

Two types of Fans: 3Pin vs 4Pin

3pin controlled by voltage, more voltage, the faster it spins.

While 4 pin is controlled by the width of pulses that drives the fan, this way it can be controlled more finely.

Thanks for the correction :)

I'm talking about in this case, I did not mean it's only used for fans. And management was just a typo, I corrected it.

Thanks! I guess I need PWM fans if I want to control them via "Sentry"?

IF it's like Ai Suite from Asus (with their Mobos) it should be able to control 3 pin fans too.

I'd prefer the flexibility of changing fan speed mid-game; rather than from the BIOS, is this possible with a program?
