ASRock's custom Striped Axial Fan delivers enhanced airflow to optimize cooling from not only the stripe structure on each fan blade but also the polishing surface on the bottom side.




 
0dB Silent Cooling

Spin For Cooling, Stop For Silence.
The fan spins when the temperature goes high for the optimal cooling, and stops when the temperature goes low for the complete silence.




 
Ultra-fit Heatpipe

Consolidated to Maximize the Contact.
The heatpipes are consolidated to maximize the contact among each others and also the GPU baseplate for the optimized heat dissipation.




 
Copper Base

Maximize GPU Contact Area.
