Problems with MSI MPG Z490 Gaming Plus fans

[Robertomcat]

Hello, good afternoon.

I am using this motherboard to do some work, I am not using it for gaming or anything related. The processor is a 10900K and is cooled with custom liquid cooling, which only has a 360 × 60 mm radiator and three Noctua Redux 1700 fans.

Each fan is connected to a separate pin on the motherboard, and from time to time the fans randomly stop working. For example, they are all running perfectly for four or five days, and the next morning one stops working. To fix it I unplug the fan and plug it back in. Then maybe four or five more days go by, and another fan is disconnected and I have to go through the same process again.

The configuration of the three fans is identical for all three, and I have them set to stop spinning when the processor is not working.

The system is up to date and all the software is up to date.

What can happen? Thanks!

Are the fans PWM or voltage regulated? Try to "force" the fan type in BIOS.
See if that change anything

Well now I don't remember very well how the fans are inside the motherboard, because I haven't touched it for a long time. What is the configuration that I should have in the motherboard management, PWM? Thank you.

It really depend on what type of fans you have ... how many PINs do they have?
Short intro (first Google result) https://resources.pcb.cadence.com/b... fans are supplied with,an extra wire for PWM.

All are PWM.

Try to set each fan as PWM in BIOS, set a curve for each as well. Disable fan control in software (Dragon Center i.e.)
In Dragon Center you can find fan control in "User Scenario" tab top right.
See if any difference

In the end I have not been able to solve, it was what you said, put in the BIOS that the fans were in PWM, I had them in DC. Thank you very much!
