My Motherboard has 2 cha_fan Connectors, but my Case has 6 Fans. How Do I Connect the Fans?

[cole2435]

My case, the 570x, has 3 pre-installed fans. I purchased 3 more fans (SP120 RGB) with the hope to improve airflow. Now, as I look at my motherboard, the ASUS ROG STRIX Z370 E, I only see 2 cha_fan connectors. I don't know if there is anywhere else I'm supposed to plug the connectors into, or if I can only have 2 fans. Please help me.

P.S, this is my first pc build.

You have to get connectors that change the connections to,4 pin and hook straight to PSU

Are all the fans in your case PWM or 3 pin voltage regulated? If PWM you can purchase a PWM fan splitter to control all the fans powered off one header on the motherboard. Akasa make a PWM fan splitter as does EK/Gelid and Swiftech also make one that supports upto 8 PWM fans.

im a bit late, but i have 6 pwm fans on a Deepcool FH-10 hub

uses sata power and connects to 1 pwm header on your motherboard, all the fans run at the speed at which you set the 1st one

Is there a difference between using a sata powered hub/controller vs a 1 to 3 splitter?

I have 3 fans connected to one header using a splitter. 2 are 2000 RPM PWM fans and 1 is a 1200 RPM non-PWM. Will they each spin at a rate proportional to their max RPM, or does the speed of one limit the speed of the others?

it would be best not to draw too much power from a single header, the hub has 10 fans connected to a single header but it uses sata power

My mobo has 1A available per header. My 3 fans together don't exceed 0.6A.

yes that is ok, as long as you dont go over 1A
