Computerkühlungslüftern

Computerkühlung refers to the systems and methods used to dissipate heat generated by computer components, primarily the central processing unit (CPU) and graphics processing unit (GPU). As these components perform computations, they consume electrical energy, a significant portion of which is converted into heat. Excessive heat can lead to performance degradation, component instability, and even permanent damage.

The primary goal of computer cooling is to maintain component temperatures within safe operating limits. This is typically achieved by transferring heat away from the hot component to the surrounding environment. Common cooling solutions include air cooling and liquid cooling. Air cooling relies on fans to force air over heat sinks attached to components. Heat sinks are designed with a large surface area to efficiently transfer heat to the air. Liquid cooling, on the other hand, uses a liquid coolant circulating through a closed loop. The coolant absorbs heat from the components via a water block and then dissipates it into the air through a radiator, which is also cooled by fans.

Passive cooling methods exist, such as larger heat sinks without fans, which rely solely on natural convection. However, for most modern high-performance computers, active cooling solutions are necessary. The effectiveness of a cooling system is often measured by its ability to lower component temperatures and its noise level. Proper airflow within the computer case is also crucial for efficient cooling, ensuring that hot air is expelled and cooler air is drawn in.
