V52 - overheating?

I switched over to my bolt+ to find all the channels were in no signal mode. I tried the basic steps and ended up unplugging every cord and the cable card. Reconnecting got it all working again.

I did notice the unit was hot to touch and after rebooting it had an ODT of 61. I'm checking 5 mins later and it is at 65.

Anyone had experience with this? The unit is always on so it was a surprise for all the channels to fail like that.
