OLC offers the world's smallest cross flow blowers/fans

with the best performance

They overcome three disadvantages of axial flow fans:

1. Axial fan hub has no contribution to the airflow, which lowers the efficiency of the airflow, specially the area close to the hub.

2. Axial flow fan generates a rotational or spiral airflow, which causes the turbulence noise when it reacts to the fins of heat sink.

3. Axial flow fan has the airflow inlet and outlet, which limits its applications where need lower profile.


The prominent difference from axial flow fan cooling is that OLC's cross flow fans provide the directional flat airflow parallel to heat sink and component to be cooled.

They eliminate a space or Z-high for the air inlet and outlet.

They are lower noise because of parallel airflow. Without the hub like axial flow fan, thye have higher cooling efficiency because the airflow runs through all fins of heat sink. Try us and see differences.
