Fans using DC interfaces are relatively early fan technology, and they are generally simpler and easier to use than fans using PWM interfaces.
The speed of fans using the DC interface is usually not adjustable, while the fan speed using the PWM interface can be adjusted through the motherboard or other controllers.
If your motherboard has a speed-adjustable CPU fan connector, then you should choose a CPU fan that uses a PWM connector.
