I just built a new PC. Using the stock cooler and without any overclocking, my Kaby Lake CPU is running at 84C (core temperature, measured by lm-sensors on Linux) when all 4 cores are under full load. Is this a cause for concern? I know that 80C is considered high, but is running at 84C all the time OK? I'm using my computer mostly for scientific purposes, so I do plan on putting it under load for many days at a time.
