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?

2A CPU is designed to be used. 20-30% usage is nothing.– RamhoundDec 17, 2013 at 16:39

possible duplicate of CPU usage at 100% for several hours, What is the impact of running the CPU at 100% for long periods at a time?, Is it ok to have 100% CPU usage constantly– Ƭᴇcʜιᴇ007Dec 17, 2013 at 16:47

techie007 - all those questions are about using the CPU at 100%, this is about using the CPU at 20-30%– Joe TaylorDec 17, 2013 at 16:58

1@JoeTaylor If 100% CPU usage isn't going to break it, then how would 20-30% usage be any different/worse? If I come back and asked "If I run my CPU at 27%-42% all day, is it going to damage it?" it'd still be the same question (IMO).– Ƭᴇcʜιᴇ007Dec 17, 2013 at 18:19

@techi007 The 100% usage questions are about burst usage, this is about continual usage. Which I consider different. I may be splitting hairs buf I do consider it slightly different– Joe TaylorDec 19, 2013 at 8:16

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%,
