P106 fan speed spikes

fan-speed
#1

Hello.

My setup contains 13 P106 from MSI.
I can’t use driver’s auto-fan since when I set fan speed to 0, it immediately go to 100%.
I’m using HiveOS auto-fan, but from time to time (few times per hour) some of my cards fan is spiking to 70, 80%.

I’ve enabled log in autofan script and this is how it looks like:

Take a look at GPU 1, all of a sudden it went to 70% and then it is slowly going back to normal.

What can cause such behaviour?
I’m on driver 418.56.
