What are you using for a CPU cooler? I see you have new Corsair RGB peripherals so probably using iCUE? You may want to check the forums for that software and devices as there are multiple posts about possible USB conflicts when the software is running to control devices instead of hardware mode configurations, including coolers connected to USB 2.0 internal headers. Definitely monitor temps or listen for fan noise disappearing. The only time my motherboard light goes out is when making BIOS changes to or within Performance Enhancer Level 3 or 4 (can't run 4 stable), saving the changes and exiting for immediate reboot.
