I've read on Cooler Master's website that these fans use a 4-pin PWM connector (not a 4-pin molex), but I've read on other sites including this one that they use 3-pin connectors. Which is it? Do they have a 4-pin or a 3-pin?

Both. 4-pin PWM for fan speed/control; and a 3-pin 5V for addressable RGB

Is this fan compatible with Asus 470 motherboard and are the LEDs functional? In addition, I have a 3 pin addressable rgb header on motherboard.

The product information does not specifically state compatibility with the Asus 470 motherboard. However, the fan has addressable RGB LEDs and uses a 4-pin PWM connector for power, which may require an adapter or a compatible header to function with a 3-pin addressable RGB header on your motherboard.
