Frequently asked questions

What is a normal temperature for the Intel Core i5-1235U?

Based on 18 community submissions, the Intel Core i5-1235U runs at an average idle temperature of 55.4°C and an average load temperature of 75°C. Anything between 62°C and 90°C under load is within the typical range for this hardware.

Is 75°C too hot for the Intel Core i5-1235U?

The safe operating ceiling for mid-range CPUs like the Intel Core i5-1235U is around 90°C under sustained load. 75°C is within the safe operating range. If you're exceeding 90°C, check thermal paste, cooler mounting, dust buildup, and case airflow.

What is the best cooler for the Intel Core i5-1235U?

For a 70W mid-range CPU like the Intel Core i5-1235U, 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.
