It happens with some fans. Just adjust the fan speed of that issue fan in bios to a speed that doesn't humm and call it a day.
Everything is normal mechanicly. But idk how is possible to make that noise. I hear it when is totally silent in room.
Maybe it is normal?
I set up rpm - different then other fan and for now it's good.
Maybe sound come because of same rmp's on both fans?
