Hi,

I´ve recently purchased the msi z370. I did connect my NZXT Kraken x72 to it and it seems that usage of its 3 fans is at most. I cannot lower it , and i am unable to see it ( cooling system ) in bios. I am pretty sure that it is connected properly but due to possibility of my mistakes i will take advices in checking the connections. Any ideas?
Thanks
