Change Header for Radiator fans?

[Vynro]

Hey guys, I am frustrated because my radiator fans that are all on my cpu 4 pin header (3 way splitter) and very loud. AI Suite 3 wont let those 3 fans run less than 100% and the motherboard i think makes the minimum 60! How can i go about getting these fans quieter?

 

I am thinking about getting a 10 way pwm spliiter, put all 3 rad fans, and 3 front intake fans on the splitter. If i plug this in to the cpu header should I be able to go lower then? Or should I put them on a chassis header? and if i do that, what do i do about the cpu fan warning in the bios! I have a little tiny VRM heatsink fan that came with my asus z390-E, should i put that into the cpu header instead of cpu_Opt?

You should be able to disable the CPU_FAN header in your BIOS.

You could also get a resistor and lower the fanspeed that way.

so then should I put my 6 fans through one controller onto say the chassis fan header?

Even tho I think it should be fine, I wouldn't do it. I don't know what those fan headers can handle and 6 fans might just be too much. I'd stick to 3 fans max per header.
Also do you know that you can then control them better?

Well, currently i have 3 per header, though the cpu header wont let me lower the 3 rad fans below 60. So I was going to put a *powered* pwm fan splitter in and hook all 6 up and control them with pwm from one header, but having power provided through the hub! and because the cpu header wont let me go less than 60, i was thinking maybe if i did chassis header it might with the controller! and what do you mean by i can control them better?

Sorry, I should've been more clear. What I meant is, that I don't know if you'll be able to go below 60% with one of the chassis fan header. You should try that out, before you buy a PWM controller. A powered PWM controller would definetily make sense here.

Okay thanks! Makes a bit more sense now!

What fans are you using and which header is the splitter plugged into?

Just get a powered hub. Also if you are using Asus suite, don’t use the auto fan speed thing. Sets the Lowest fan speed and won’t let you go lower. 

 

I have the issue but just use a hub with my noctua 2k fans on the cpu header. 

 

Doesnt work if you mix 3pin and 4pin though.
