Help with case fans setup and control

Helllo everyone,

I've been having some troubles with the cooling on my new build (it has an RX 580 "HOT LAVA" Edition) and got 4 case fans + CPU AIO. So, my mobo only has 2 headers for sys_fans which 1 is already occupied by the CPU AIO fan and only got space for 1 out of the 3 case fans I have. Now, I know I'm able to connect them to the PSU but that only makes them go extremely loud and I would like to configure the fan speeds as tempereture rises.

 

Question is, what Fan speed controller or setup do you recommend to be able to control the speed via software. I saw the Corsair Commander Pro but seems too much to spend for the purpose. Also saw THIS in Aliexpress, would it work?

 

Thanks!

 

Setup

CPU: Ryzen 5 1400 with Corsair Hydro H60

GPU: RX 580 MSI GAMING X

CASE: CoolerMaster Q300L

MOBO: MSI B450M Gaming Plus

FANS: 4 Corsair AF120 + 1 CoolerMaster ML120

The powered pwm splitter would only work for controlling 4pin pwm fans. The fans would receive 12v which means 100% rpm for 2-3pin fans. 

What fans are you using?

3-pin fans don't necessarily mean 100% at all times. Depends on motherboard. MSI motherboards for example can step power on 12v down to ~7v for ~50% and even ~9-10v for ~75%. Everything being approximate(~) because it all depends on fan, motherboard, and psu power delivery efficiency.

I have 4 Corsair AF120 and 1 Coolermaster ML120. All are 3 pin.

Yes I was able to connect 1 to the mobo ( which is the only available one I have) but the other 4 fans are all connected directly to the PSU. And it sounds like a wind tunnel , works great but can't listen to my own thoughts.

Did you mean ML120L? That cooler comes with a 4pin MF120R fan. 

Which AF120's do you have? There are different variants such as Quiet Editions, Performance Editions, and LED.

You can plug two of the Corsair case fans into each sys_fan header with standard splitters and the Cooler Master AIO fan into the cpu_fan header. https://es.aliexpress.com/store/product/Mainboard-CPU-4-PIN-Fan-Extention-Cables-PWM-4P-Adapter-Cable-Computer-Case-Mainboard-4-PIN/605305_32961035056.html?spm=a219c.search0104.3.11.6e0f3fbfxhUP7m&ws_ab_test=searchweb0_0,searchweb201602_8_10065_10130_10068_10890_10547_319_10546_317_10548_10545_10696_453_10084_454_10083_10618_10307_537_536_10059_10884_10887_321_322_10103,searchweb201603_54,ppcSwitch_0&algo_expid=4115f28e-6643-4fcd-a827-68ff28a463f6-1&algo_pvid=4115f28e-6643-4fcd-a827-68ff28a463f6

The pump can be plugged into the psu with a molex fan adapter. 

The fan software in the motherboard settings should be plenty for control.

Thanks, I did have the pump on CPU_Fan works better plugged directly to the PSU.

 

As for the 2 fans on a single mobo header, wont it overload the Mobo?

Will the fans be able to reach full speed with these fan splitters?

No, it won't overload the headers and the fans can run at full speed. Fan headers generally support up to 1A each and the AF120 LED 2018's you're using draw 0.3A at max rpm.

Tried the recommended setup and got a couple 3 way splitter for the fans, it worked perfectly to control all of the fan and adjust the curve as temp rises.

 

Temps are now at an acceptable range and quiet when not underload.

 

Thanks all!
