When i play CPU intensive games such as GTA 5 my CPU usage is usually 80+. However my temperature never goes about 70c and usually stays around 65c. So the simple question I can't find a straightforward answer to is does the usage matter much if the temperature is fine?

I have an i5 3570k @ 3.4GHz
