1. "Tiny Cooling Fan" improved hydrodynamic design - modify, adjust or introduce new blades and frame design, and thus enhance the effectiveness of the fan is a designer who always demands the most fundamental improvements in the way;
2. The extension of "Tiny Cooling Fan" life - Improved bearings, motor design, the use of new materials, the successful introduction of technology in various fields, in order to further extend the life of the fan, the design and manufacturer who racked rack their brains;
3. Reduce the "Tiny Cooling Fan" operating noise - fundamental solutions to reduce friction and vibration, improve performance, and the same thing can be described as the first two, but due to the current "mute" more and more attention, some manufacturers began as a center re-entered into the development plan, allocate research and development efforts.
