What is a fanless computer and how is it different from a regular computer?

Fanless computers use passive cooling (metal casing, heat sink fins) instead of fans. Compared to ordinary computers, they have no mechanical fans, produce near-zero noise levels, and are well sealed to prevent dust. Ordinary computer fans easily accumulate dust, produce 30-50 decibels of noise, and have a lifespan of only 2-3 years. For example, the RK3288 fanless computer, equipped with a quad-core Cortex-A17 architecture chip (clocked at 1.8GHz), uses an all-metal body for passive cooling and can operate stably in temperatures between -10°C and 60°C. This makes it more adaptable to environments with similar specifications (suitable for temperatures between 5°C and 35°C). Furthermore, the RK3288 fanless computer has no fan losses, resulting in a 30% longer lifespan than ordinary computers. It also avoids dust accumulation and system crashes, making it suitable for scenarios such as industrial control and medical equipment.
