Shouldn't be, if your system case, fans and vent holes are properly designed
and capable of removing the heat they need to.
If you have a system with poorly designed cooling then the biggest heat
sources will probably fail first, and graphics cards are big heat makers.
Fanless cards require even more careful consideration of airflow through the
case.
24/7 operation also needs to be considered in the overall system design, radio
gear used to carry two specs, "CCS" and "ICAS" (Continuous Commercial
Service, Intermittent Commercial and Amateur Service), CCS needed better
cooling systems.
Given your history I'd suspect a poorly cooled system, or perhaps you have
broken a mirror in the last 7 years.
