Constant CPU utilization on consumer hardware



A computer in a manufacturing environment is running software that is in a constant communication loop with a PLC. An artifact of the implimentation is ~20-30% CPU utilization 100% of the time (24/7). Will the constant CPU cycling have an impact on the longevity of this hardware?


Answer



The simplest answer is not really, computers are designed to be used over long spans of time(Example, Google's server, Amazon's servers, your router, etc), though Is the performance of a CPU affected as it ages? makes the point that there is SOME wear and tear from the age of the component. Bottom line: Unless your CPU is running very hot, it shouldn't be very limiting on the life span to keep at 30%,
