Frequently asked questions

What is a normal temperature for the Intel Core i3-8145U?

Based on 2 community submissions, the Intel Core i3-8145U runs at an average idle temperature of 52.5°C and an average load temperature of 79.5°C. Anything between 73°C and 85°C under load is within the typical range for this hardware.

Is 79.5°C too hot for the Intel Core i3-8145U?

The safe operating ceiling for entry-level CPUs like the Intel Core i3-8145U is around 85°C under sustained load. 79.5°C is within the safe operating range. If you're exceeding 85°C, check thermal paste, cooler mounting, dust buildup, and case airflow.

What is the best cooler for the Intel Core i3-8145U?

For a 65W entry-level CPU like the Intel Core i3-8145U, 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.
