My old trainer told me 4K boxes run hotter, and now I check airflow on every single job
He came out with me on a job in Riverside last week and pointed at a 4K box I had tucked in the back of a media cabinet with 2 inches of clearance, saying the heat is what kills them before the hardware ever does. I started leaving 4 inches around every box since then, and no callbacks yet. Any of you notice more heat failures on the newer 4K units compared to the old HD ones?
