Eh it might be one of the better ones on here but it could still be a lot better for the price, the Trio destroys it from what I can see. I assume you're not referring to the Aorus logo, in that case I have no LEDs on next to my PCIE connectors.
Send it back now in my opinion before it dies entirely. What PSU do you have out of curiosity?
A couple people have had that issue, mine worked out of the box, I have noticed that Afterburner won't show my fanspeed, it says it's 33% all of the time which isn't true. As much as Aorus Engine sucks at least it's not giving me false data. I have no Scanner option on my Afterburner either yet it's up to date. I'm currently idling at 30c with 0% fanspeed. I'll report back with gaming temps now that the semi passive option is on. Afterburner and Precision have no option for semi passiveness on this GPU. Seems unique to Aorus Engine.
Try rolling your drivers back to an earlier one. I have a game that is crashing when it didn't a few days ago, the only change is the driver and a game update but the dev blames the driver.
