Hello!

I have a Z390 Aorus Pro motherboard and 6 case fans connected to it. I installed the Smart Fan 5 software to control the fans via the motherboard, easy enough and (almost) works as it should.

The only problem i have is that sometimes, like once or twice a week, one fan starts to speed up to max speed and two of the other fans turns completely off.
To fix this i have to open the Smart Fan 5 software and apply my settings again. I run it on performance. I tried making my own fan curves and changing the mode to quiet but nothing fixes it.

Anyone knows how i fix it?
Thanks!
