Hello.

I have just received my second mikrotik 1016-12g
I hope this is just a bug and maybe someone has an answer my fan on the back seems to keep squeaking for a wile and then goes back to normal this has been going on all day.
I have also noticed that the fan switched auxiliary and then back to main on it`s own.
Is there an easy fix for this or is my mikrotik broken?
Thanks for any help
