12 Fans Need to be Controlled

[lgilst83]

Hi, I just built my rig and its running 4 radiators and 12 fans (Corsair SP120 High Performance Fans). I need to be able to control the fan speeds, but I don't know how to do this? I have a Corsair AXi1200i PSU and a ASUS Maximus VI Formula Motherboard.

All of the fans are hooked up, but none of them hook into the motherboard.
To make a long story short, and get to the question... Is there a way I can control the fan speed of all 12 fans somehow? I've tried using a 4pin extension to hook a swiftech 8 way splitter to the mobo but that doesn't allow me to control them? Im only guessing im going about this all wrong... Any help will be GREATLY appreciated!

12 fan?
Way too much in my taste but.
Since a splitter doesnt work for u
U better get a seperate fan controller

yes, you can buy single 3 or 4 pin connector to multiple connectors. A single PWM signal controls all fans. Usually you use the speed signal from one fan back to the mobo.

So I have Y splitter that connects them all, and I can use the one extension to plug into the motherboard and then that will allow me to control the fans all at once? Say if I plugged it into Chasis fan 2?

I think You will feel Cooler by sitting on chair in front of PC with those 12 fans

I got this one for 4 fans, you can daisy chain them.

good thing is it takes power from your PSU, not your mobo. It only takes the PWM signal from your mobo and feeds the speed signal back from 1 fan to your mobo.

I made my own fan controller using a few POTs. Not the neatest work but still works fine

I connect my extension to chasis fan 1,2, or 3 but still have no control over all of the fans the extension is hooked too? why not? I should be able to right? Seriously this is aggravating because they are really loud. :\ Am I connecting it to the wrong pwm connector on the mobo?

Also the system is fully liquid cooled... so no CPU fan..

are the fans definitely PWM controlled fans? There are some which aren't and rely on a resistor to drop the voltage.
