Let's assume I have a processor running at 4.0GHz clock speed with 1.200 Vcore voltage. I could also overclock this to 4.4GHz with the same Vcore voltage. Both settings have the same Vcore voltage, but one is 400MHz faster than the other. There is minimal heat increase with the one that runs 400MHz faster. Does the clock speed affect the lifespan of the CPU, or is only heat and the voltage?

Well, a higher clock speed will, as a general rule, lead to higher heat. Regardless, the wear and tear caused by making a processor work an extra couple millions of cycles a second is fairly negligible compared to any heat or voltages you subject it to.

Semi-conductors, as a general rule, gain or lose half their life for every 10C of operation. I can't speak much for voltages, but it is how much energy you're pumping into those poor little transistors.

A processor designed to run more than 10 years..and hardly fail..(i'm still using a -barely legal- 18 years old pentium 133 mmx as my home internet server :D)
yes, too high temp and too much voltage will kill it..

as long as you keep it in the voltage and temp safe area, at least you can run your processor for next 5 years..
but i doubt that you still use the same processor in 2018..:D
