What is the ideal temperature for a computer processing unit (CPU)?

While ideal temperature ranges vary between CPU brands and models, most processors should run between 70 and 90 degrees Celsius. Modern processors should not exceed 95 degrees C.

When a computer's processor overheats, it can cause a myriad of issues, including causing the computer to run slower and randomly shut off or restart. Keeping the computer clean inside can help maintain a cooler CPU, as can ensuring a proper amount of airflow around the computer. Computer fans and thermal paste can also help keep the CPU cooler. A CPU that continuously runs too hot often has a shorter life expectancy.
