The Intel Core i7-8700 runs at an average of 77.4°C under load based on 8 community submissions. The hottest 10% of submissions report temperatures above 93°C, while the coolest 10% stay below 58°C. Idle temperatures average 60°C.
High-end CPUs typically run 70–85°C under load with a good air or AIO cooler. Sustained loads at 90°C+ usually indicate a cooling issue, dried thermal paste, or restrictive case airflow.

Based on 8 community submissions, the Intel Core i7-8700 runs at an average idle temperature of 60°C and an average load temperature of 77.4°C. Anything between 58°C and 93°C under load is within the typical range for this hardware.
The safe operating ceiling for high-end CPUs like the Intel Core i7-8700 is around 90°C under sustained load. 77.4°C is within the safe operating range. If you're exceeding 90°C, check thermal paste, cooler mounting, dust buildup, and case airflow.
For a 75W high-end CPU like the Intel Core i7-8700, a quality 240mm AIO or a high-end dual-tower air cooler (Noctua NH-D15, Thermalright Phantom Spirit) is generally sufficient to keep load temperatures well within safe limits. Higher TDP variants (overclocked or PBO-enabled) benefit from 360mm AIO cooling.
