Fans Running at High RPM

[LuX_]

Hi,

 

So I just upgraded my system fans to Corsair ML120 Pro Blue and they are running very loudly. I did some research and adjusted my smart fan mode rpm%s and the fans are still running at 1400RPM my other system fans and CPU fans are running between 600-800 rpm. I have 4 system fans and 3 motherboard headers. One of the ML120 fans is on a splitter with the cooler master fan and the cooler master fan is running fine. Can anyone offer a solution so that they run at a lower RPM? 

 

 

Specs

CPU - I5 4690K

GPU - MSI RTX2080 Trio

Fans - ML120 pro, (and a bitfenix and coolermaster fan that I'm not sure what the name is)

Mobo - MSI M Power Z97

Have you tried adjusting the fan curve to be less aggressive?

^^ yuuuuuup you should do that

What should an ideal fan curve look like?

Not too sure how to use this software but AUXTIN2 is a bit of an anomaly?

So when I remove the fan splitter and just have my CPU cooler and the 2 other fans they all run normally? Could this be that the Fan Splitter is not PWM?

 

I also changed the fan curve so that is more liner and not as aggressive and it didn't fix change anything

Depends on if you want better cooling or less noise. Tune it until you find the right balance.

 

Here's one of my case fan's curve:

 

Turns off until in-case temps reach 36c, then jumps to 36%. Increases to 65% at 50c, and 100% at 62c. (That's for the temperature of my motherboard, not my CPU.)

 

It's really something that you'll need to play around with to find the right balance for, since it'll be different for pretty much every case and fan configuration.

That's possible. Does the splitter have three pins or four pins?

What software do you use to do that because my fan control in my bios is very restrictive and doesn't have an option for 'turn off until _' and the lowest I can set them to is 50% @ 40C. There is a grey square which I have no control over which I'm assuming is the below the bottom one I set and it is stuck at 60%

I use ASUS' AI Suite 3 (for ASUS motherboards). You'll have to use MSI Command Center for in-windows control over your fan curves.

The only fan headers on your motherboard that support pwm are the cpu_fan headers. The sys_fan headers only support dc control. 

Run your ML's off of the cpu_fan headers.

silence? 

 

You may need to back it a little but bit..

Nah, they don't get loud at all. They're running based off the motherboard temp (which is close to the air temp in the case), not the CPU, AIO liquid, or GPU temps.
