What is the optimal temperature range for laptop CPUs?
The optimal temperature range for laptop CPUs typically falls between 30°C to 70°C (86°F to 158°F). Under normal operating conditions, such as web browsing or document editing, temperatures around 30°C to 50°C are common. However, during intensive tasks like gaming or video rendering, it’s normal for temperatures to rise to 70°C, and in some cases, slightly above.
When a laptop’s CPU temperature approaches or exceeds 80°C (176°F), it may trigger thermal throttling as a protective measure. This means the CPU will reduce its speed to lower temperatures, which can impact performance. Prolonged exposure to temperatures above 85°C (185°F) can potentially damage the CPU over time, so it’s best to keep the operating temperature within the optimal range.
What happens if a laptop CPU gets too hot?
If a laptop CPU gets too hot, it can lead to several performance-related issues.
