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.

Your temperatures are far too high, they should be in the upper 60s maximum at stock speed for everything except benchmarking. Poor airflow inside the case can also increase temperatures [in-case ambient]. My temperatures do not go above 60 degrees C [usually upper 50s max] while encoding videos with my Intel i7 7700K clocked at 4.6GHz on all cores with Noctua NH-14S fan speed set to 100%.

I do not know how much room you have in your case [vertical] or how much room you have [horizontal] over the motherboard. You need to measure [with a wooden ruler] how far it is from your motherboard PCB to the outer edge of the case.

Noctua makes some of the best coolers, even better than some water coolers.

Noctua CH-C14 can be good if your case is not wide...

Noctua CH-C14 can be good if your case is not wide enough for a tall cooler, however, last year I checked prices and Newegg was gouging customers at that time, and I believe it has been replaced by the CH-C14S [it uses a single fan]. http://noctua.at/en/products/cpu-cooler-retail/nh-c14s

I am using the Noctua NH-U14S. It is smaller than the D15 that The_Staplergun mentioned in his post above yet performs on par with them. http://noctua.at/en/products/cpu-cooler-retail/nh-u14s

The little brother to the NH-U14S is the NH-U12S. It does not perform quite as well as it's larger brother, yet is still in the top of the air cooling performers. http://noctua.at/en/products/cpu-cooler-retail/nh-u12s/specification
