I have the same Problem an at first I thought your Video was the solution, but then I realized, that the MSI Control Center does not save the Settings you make... So after you restart you Computer everything is back to before and the fans spin uneccessary fast.
I tried SpeedFan, but it is extremely compliceted and I wasn't able to Change fan Speeds at all...
It's a shame that MSI does not allow fan Speeds below 50%..
