What is Thermal Throttling?
Thermal throttling is a mechanism used by computer hardware to regulate temperature. When a processor or graphics card operates at high speeds, it generates heat. If this heat is not dissipated efficiently, the component’s temperature can rise to dangerous levels, causing damage or failure. To prevent this, the hardware reduces its speed, thereby decreasing heat generation. This reduction in speed is known as thermal throttling.
Causes of Thermal Throttling
Thermal throttling can be caused by various factors, including inadequate cooling systems, high ambient temperatures, and dust buildup. When a computer’s cooling system is not capable of dissipating heat efficiently, the temperature of the components can rise, triggering thermal throttling. Similarly, high ambient temperatures can exacerbate the problem, as the cooling system has to work harder to cool the components. Dust buildup can also block airflow, reducing the effectiveness of the cooling system and increasing the risk of thermal throttling.
Effects of Thermal Throttling
Thermal throttling can have significant effects on a computer’s performance. When a processor or graphics card reduces its speed, it can lead to reduced frame rates, lower processing speeds, and increased latency.
