PCfläktar

PCfläktar, or PC fans, are essential components in a computer's cooling system. Their primary function is to move air across heat-generating components such as the CPU, GPU, and power supply, preventing them from overheating. Overheating can lead to performance degradation, system instability, and even permanent damage to hardware.

These fans come in various sizes, with 120mm and 140mm being the most common for case cooling, while smaller fans are often found on CPU heatsinks and GPU coolers. They are typically powered by the motherboard or directly from the power supply unit. Fan speed can often be controlled, either manually or automatically through motherboard sensors, allowing users to balance cooling performance with noise levels.

PCfläktar vary in design and features. Some are optimized for high airflow, moving a large volume of air, while others focus on static pressure, which is important for pushing air through restrictive elements like heatsinks or radiators. Bearing types also differ; sleeve bearings are generally quieter but have a shorter lifespan, while ball bearings are more durable but can be noisier. Fluid dynamic bearings offer a good balance of both. The number of blades, their shape, and the motor's quality all contribute to a fan's overall performance and acoustics.
