Narrow bezel CPU fans are specifically engineered to address the space constraints in some modern computer cases. These cases are often designed with a focus on compactness and aesthetics, leaving limited room for traditional-sized CPU fans. The narrow bezel design allows the fan to fit into tighter spaces while still providing effective cooling. The reduction in bezel width is achieved through careful engineering of the fan housing and blade design. The blades are typically designed to be more slender and efficient in generating airflow despite the reduced overall size of the fan.

One of the main advantages of narrow bezel CPU fans is their compatibility with small form factor (SFF) and mini-ITX computer systems. These systems are popular for applications such as home theater PCs, media servers, and compact gaming rigs. In such systems, every millimeter of space matters, and a narrow bezel CPU fan can make a significant difference. For example, a narrow bezel 92mm fan can often provide sufficient cooling for a moderately powered CPU in a mini-ITX system without taking up excessive space. Additionally, these fans are usually designed to be relatively quiet, as noise can be a more prominent issue in small and enclosed computer cases. They may use advanced bearing technologies and optimized blade designs to reduce noise levels. However, due to their smaller size and narrower bezel, narrow bezel CPU fans may have slightly lower airflow and static pressure compared to standard size fans. But in the right application, where space is at a premium, they offer an excellent compromise between cooling performance and space utilization.
