MSI MAG Forge m100r ARGB issue

[elgsuset154602cf]

Hey, i've been using this chassing without any issues for the past 1.5y, but suddently the ARGB lighting on the fans stopped working, sometime it works others it dosen't wich doesn't make much sense.
The strangest thing is that if I remove the SATA connector and hotplug it, the ARGB works againg (obiusly until a restart my computer).

Any idead?
Thx

Do you mean SATA power connector? or just the SATA cable for HDD/SSD? The RGB should not have anything to do with the SATA.
Can you plug in the ARGB device directly to mainboard without the HUB and see if it works?
