I just built a new 6600k skylake system I have just started to get in to overclocking. The system I built is 6600k msi carbon pro gamer 16gb corsair led 2666 memory. I overclocked the cpu to 4.5 ghz at 1.16 volts I have tested the system with aida 64 for 12 hours no problems also have done another 8 hours of gaming. My max temp during the 12 hour aida 64 test was 57 c. Is this normal or do I have a really good chip.
