What is a good idle cpu temp?

A good idle CPU temperature typically falls in the range of 30-40 degrees Celsius (86-104 degrees Fahrenheit). This temperature range signifies optimal cooling and efficient operation of the CPU without being too hot or too cool. It is important to monitor and maintain a good idle CPU temperature to ensure the longevity and performance of the processor. If the CPU temperature consistently exceeds 40 degrees Celsius even at idle, it may indicate inadequate cooling or ventilation in the system and should be addressed to prevent overheating and potential damage to the CPU.
