Roku Premiere suddenly overheating?

[MrHT]

I bought a Roku Premiere last October and it’s been rock solid for the six months I’ve owned it. However, I just encountered a unusual problem today. I was watching for just 30 mins and got the warning message on my screen that my device is overheating. I felt the Roku and it did feel unusually warm. I’ve never had this problem before and there have been times where I’ve watched for hours with no overheating issues.

I’ve done some google searching and it appears many people have had this problem, but am wondering if this is a cause for concern. Is this a sign that the Roku is already dying?
