[SOLVED] CPU fan runs too fast, fan curve doesn't stick in BIOS (MSI B450-A Pro MAX)

[Countess_C]

The fan curve doesn't want to stick in BIOS, so the CPU fan runs at full, or almost full speed all the time, making noise. I have tried to set the fan curve to Default, and it changes in BIOS, but it doesn't seem to affect the fan speed.

Motherboard: MSI B450-A PRO MAX
CPU: 3400G
Cooler: AMD Wraith Prism (a leftover from another build)

The BIOS is the one that came with the motherboard. E7B86AMS.M30

Any tips?

The Prism should be plenty to keep a 65w cpu in check. Under normal circumstances.

Are you using Ryzen Master?

How is the paste?

What temps are you seeing?

What vcore is showing in RM or HWInfo64?

 

[Countess_C]

No, Ryzen Master is not installed.

The paste is the one that came on the cooler. (Thought about replacing it with Cryonaut, but as you say, this cooler should be more than good enough!)

I'm going to install the HWInfo64 and check the vcore and temps later when I get home.

Faulty heat sensors or maybe the thermal paste has air bubbles, meaning it'd affect your temps negatively.
Might be a bios problem, i suggest updating your bios to the latest version

Many possible solutions to this problem ex. faulty mb, cooler, bios, thermalpaste

Would it be a good idea to install MSI Command Center?

CPU is 26º C and the fan is running at 1800 RPM.

I updated BIOS and set the fan controller to PWM and made my own curve. Have rebooted a couple of times and it seems to work now.
