Maximize performance and minimize noise!
The optional fan is specifically designed to provide sufficient airflow over the CPU power modules and chipset area when water-cooling or passive-cooling is utilized, ensuring effective heat dissipation for the entire system.

Maximize Water-Cooling Performance
The optional fan provides sufficient airflow over CPU power modules and chipset area in the event of using water-cooling or passive-cooling equipment. This protects the system from overheating due to the lack of airflow and insures the motherboard’s lifespan.

Minimize Rotational Speed and Noise
After countless experiments, 3,000 rpm was the best rotational speed of the optional fan to make the chipsets and MOSFETs temperature low enough and decibel acceptable. With this optional fan, one can enjoy quiet operation without system overheating problem when using water-cooling equipment.
