An added external fan might be the only solution for heat concerns and issues that would most likely be contributor for those cheap off the shelf HDMI boards failures found in cheaper AV receivers and processors.
However, I’ve had my Classe SSP 800 for years without a single issue with its HDMI board. But I sold the SSP 800 to my cousin last year cause I wanted Dolby Atmos & DTS-X setup which the Classe lacks supports of. But again the Classe SSP 800 wasn’t cheap at all and did retail for $9500 when purchased brand new when it was in production up until 2017. All components and parts that go into this unit are all high grades and not some cheap off the shelf parts found in Marantz, Onkyo/Integra, Denon, Yamaha, Pioneer, Sony AV receivers or processors.
My cousin still has the SSP 800 and he said it’s still going strong, the unit is roughly 8 to 9 years old.
