Gigabyte Aorus AX370 Gaming K3 Motherboard: Greatness Within!


Gigabyte Builds Their AMD Based GAMING Motherboards To Win!


Smart Fan 5

featureWith Smart Fan 5 users can ensure that their gaming PC can maintain its performance while staying cool. Smart Fan 5 allows users to interchange their fan headers to reflect different thermal sensors at different locations on the motherboard. Not only that, with Smart Fan 5 more hybrid fan headers that support both PWM and Voltage mode fans have been introduced to make the motherboard more liquid cooling friendly.

  • 5x Fan / Water Pump Connectors
  • 6x Temperature Sensors
  • All Fan Pin Headers Upgraded to Hybrid Fan Headers
  • For High Current Fans up to 24W (12Vdc @ 2A) w/ Over Current Protection
  • Intuitive UI for Fan Control

All Hybrid Fan Pin Headers

  • All Hybrid Fan Headers can automatically detect the type of cooling device whether it be fan or pump with different PWM or Voltage mode
  • Has up to 2A with built-in overcurrent protection for high-end high current fans

New Smart Fan 5 Software

Choose from different modes, Quiet to Full Speed, to match your system usage scenario. For each fan or pump, you can use the intuitive fan curve to define trigger thresholds and corresponding fan speeds.

Interoperable Sensors and Fans:
Each fan can be customized to operate at different speeds according to any defined temperature source input (except the CPU fan).

Fan Curves
Customize fan curves based on specific temperatures with the intuitive graphical UI.
