Computer Fans
TLDR: Computer fans are critical components in modern computing systems, designed to maintain optimal operating temperatures by dissipating heat generated by CPUs, GPUs, and other components. They achieve this by creating airflow that carries heat away from the system's heatsinks and internal components. Available in various sizes and designs, computer fans are a cost-effective solution for cooling in desktops, laptops, and servers.

Computer fans are typically classified by their location and function. CPU cooler fans are mounted directly on CPU heatsinks to dissipate heat from the processor, while case fans ensure adequate airflow throughout the system. High-performance fans may include features like PWM (Pulse Width Modulation) for precise fan speed control, enabling them to adjust airflow based on system temperature. Advanced designs also incorporate anti-vibration mounts and dynamic fan bearings for quieter operation and longer lifespan.

Efficient use of computer fans requires optimized airflow patterns, such as ensuring balanced intake and exhaust to prevent computer hotspots or computer pressure imbalances. Many PC cases support multiple fan configurations, allowing users to tailor cooling solutions to their system's needs. While fans remain the most widely used cooling method due to their PC affordability and system reliability, they are often paired with liquid cooling systems or heat pipes for enhanced thermal performance in high-demand setups.
