Datorfläktar

Datorfläktar, often referred to as computer fans, are essential components in a computer system responsible for dissipating heat generated by various electronic parts. These fans actively move air to cool down critical components such as the central processing unit (CPU), graphics processing unit (GPU), power supply unit (PSU), and the overall case interior. Without adequate cooling, these components can overheat, leading to performance degradation, system instability, and potentially permanent damage.

There are several types of datorfläktar, each designed for specific purposes. Case fans are the most common, circulating air throughout the computer chassis. CPU coolers typically incorporate a fan mounted on a heatsink to draw heat away from the processor. GPU coolers also feature fans, often integrated with a heatsink, to manage the high temperatures produced by graphics cards. PSU fans are built into the power supply to cool its internal components.

The performance of a datorfläkt is typically measured by its airflow (measured in cubic feet per minute, CFM) and static pressure. Airflow indicates how much air the fan can move, while static pressure is its ability to push air through resistance, such as heatsinks or filters. Fan speed, often adjustable, is measured in revolutions per minute (RPM) and directly impacts noise levels. Higher RPM generally means more cooling but also more noise. Datorfläktar are crucial for maintaining optimal operating temperatures and extending the lifespan of a computer.
