Custom fan curve problems

[msvelev]

Hi, 

I'm running:

Ryzen 3600

MSI Mortar MAX

Gigabyte 1660 Super

In Cooler Master Q300L

With 3 CoolerMaster MF120R and the stock case fan.

 

The problem is that the cooler master fans are REALLY REALLY LOUD. The stock case fan is DC and is really quiet.

I've setup a custom fan curve through BIOS, but it seems to be partially ignored. My curve runs them at 10% PWM until the CPU hits 70C, but they start to get really loud at about 55.

Do you have any idea why the custom fan curve set in BIOS seems to be ignored? Reviews of these fans suggested them as somewhat quiet, but that's not the case.

 

Thanks! 

 

EDIT: Forgot to mention that they're connected through the same header with a splitter.

What headers are they connected to? Have you remembered to change the header from DC control to PWM control?
