Fan-Control

   Hello Everyone,

few weeks ago I received my Z370 Extreme4 with an i7-8700k.
Yesterday my new chassis (corsair RGB460x) arrived as well.

Now I wanted to setup my fans and i really dont know how to.

I connected all as they should be on the MB.
When I open BIOS I can adjust different Temperatures/Powers for each fan.
But on fan 3 I can choose between "PWM" or "DC" mode.[URL=https://www.dropbox.com/s/3dndv9k8t4oat7p/IMG_20181203_180854.jpg?dl=0]Picture[/URL]

I have 3-core-fans. So, if I choose PWM its much more louder than with DC.
What exactly shall i choose? Which settings i should use?
My actual Hardware is [URL=https://geizhals.de/?cat=WL-938813]CLICK [/URL]

Can u tell me which settings i should use?

It would be really nice of you!

Thanks in advance.

	"PWM" oder "DC" depends on your fan: - PWM-fans are using a 4-pin connector (V+, V-, Tacho and PWM). The PWM pin sets the speed of the fan with a dedicated digital signal. - 3-pin fans do not have the PWM pin. Their speed is set by voltage between ca. 7V and 12V. That's why a 3-pin fan runs at full speed if set to "PWM" (no PWM connector). On the other hand can a 4-pin fan be controlled by PWM OR voltage. In this case you should choose PWM. Some BIOSes have an "AUTO" function, that means, they detect PWM or DC automatically.
