i just bought an inspiron 5558 and it has a core i7-5500u 5th gen processor in it. i was on the dell support site and there as an option to run diagnostics so i selected it, the diagnostic feature ran a stress test on my cpu and it took my cpu usage to 100 percent and my cpu fan also started. after that every thing was normal and the cpu and computer passed the test. i just wanted to ask that have i damaged my cpu by running the stress test on it.? Rite now cpu temp is normal 25 roughly.
