Finally, someone else posted their temps. I started a thread long ago when the Ultra first came out reporting temps like that and even higher. Nobody would ever go into the menu and post their temps. https://forums.roku.com/viewtopic.php?f=28&t=96790
I guess it is normal though since I've had it running at those temps for almost a year and a half now.
