Benchmarks: Temperature
It has been smooth sailing for the benchmarks thus far, but under-load temperatures reveal that the combination of high overclocks and low noise are a challenging balancing act. Both the CPU and GPU get noticeably warm, and our conversations with Scan's engineers suggest that Core i7-8700K could become a silicon lottery.
The engineering sample we received for review had no trouble maintaining 5GHz across all cores with just 1.275V. The first chip Scan tried needed 1.375V to make it happen, and the second, residing in our review machine, managed 5GHz with 1.325V.
Those of you with good memories will recall that Core i7-7700K began life at 5GHz in some machines, but mixed headroom on retail parts inevitably led to system integrators dialling said chip back down to 4.8GHz on most builds. It remains to be seen whether or not Core i7-8700K will widely accept 5GHz when the dust settles, but the 3XS Z370 Vengeance Ti remains a good way of guaranteeing such high speeds with the added peace of mind of a three-year warranty.
