Today I cut a hole the size of the label on the underside of the case.
Turned the device upside down.
Edited the vfd.conf file to both reverse the digits and to turn them upside down also, so the time/temp shows correctly with the device upside down.
Playing a UHD Satellite channel into a FHD monitor (as before) the temp maxes out at 65 C.
My intention is to find a heatsink soon to replace that metal plate that is fitted by default in the device with a better cooler, and I am expecting the max temp to drop to 60 C.
That is my aim … to get the temp during this test to 60 C or below.
It appears I am on the way …
