I recently updated the CPU, Motherboard, and RAM on my system. I am now running a Ryzen 7 2700x on an MSI b450 Tomahawk with 16GB GSKill Ripjaws DDR4 3200. The system boots and runs without error. However, when I shutdown the system all fans and RGB's on the entire system run at full blast; even a set of fans that are connected directly to the power supply do this, but did not before and I didn't touch their cables when upgrading. I tried flashing the BIOS and/or clearing the CMOS. No change. Thoughts? Help? Suggestions?
