PC Refuses to Turn Off Annoying Red RGB Light, Now My Motherboard Stands as Aesthetic Bother
Many users, including myself, have encountered an issue with the RGB lighting on the Asus Prime X370-Pro motherboard. Despite turning off the system, the RGB lightstrip on the motherboard continues to glow, even when the system is under the desk and out of sight.
The problem lies with the Asus Armoury Crate software, which controls the RGB lightstrip on the motherboard. Despite attempts to disable the lights via the software, the lighting defaults back to a red glow when the system is off. There seems to be no official or simple software toggle to prevent this behavior.
This issue is particularly frustrating because the RGB lightstrip is coordinated with the RAM and CPU cooler to emit a cyan glow when the system is on. However, even when the system is off, the RGB lightstrip can still be seen through the tinted glass on the Fractal Design Meshify C case.
Asus Armoury Crate officially supports lighting control mainly on newer models from the X570 series onward. Since the X370 is an older generation, full Aura Sync features may not be implemented or may default to keeping lighting on.
There are a few possible workarounds that users have tried, although none are officially confirmed by Asus. One such workaround is to disable the "ErP" setting in the BIOS. Enabling ErP (Energy-related Products) mode in BIOS can cut power to certain components on shutdown and may lead to the RGB lights turning off. Another workaround is to physically disconnect the RGB cables if they are accessible.
Some enthusiasts have attempted custom firmware or software to suppress RGB lighting on unsupported models, but this is risky and not officially supported. It is also worth checking for Armoury Crate software settings or updates, as occasional updates add better motherboard support.
In conclusion, due to the older nature of the Asus Prime X370-Pro motherboard and the default behavior of Armoury Crate automatically enabling RGB lighting on shutdown, there is no straightforward method to disable the RGB lighting fully when the system is off without resorting to BIOS-level power settings like ErP or hardware disconnection.
For future builds, I am considering components that use OpenRGB, which may provide a more reliable solution to RGB lighting control. I might also opt for a stealth build or a case without a side panel to minimise the visibility of any remaining RGB lighting.
This issue is not unique to me, as Sarah Jacobsson Purewal expressed similar views in a previous article. The frequent updates and prompts for account login or wallpaper addition in the Asus Armoury Crate software are also annoying and can be a source of frustration for many users.
