I recently got a Lenovo ThinkCentre M900 from a friend, though it was missing a storage device. So naturally I got a hard drive and ended up having to get an entirely new power supply just to connect it to said hard drive. Then I found out Lenovo uses proprietary 10pin connectors so I had to get an adapter. Finally after all that I installed windows 10, but the fans are so loud. I booted into BIOS but I can't seem to find any settings related to fan control. It sounds like a hotel AC unit and I can't find anything online regarding it. I've updated the BIOS and everything someone please help!
