Gigabyte GA-Z270X-UD3 Intel Z270 LGA 1151 (Socket H4) ATX motherboard

Smart Fan 5With 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.All Hybrid Fan Pin Headers Hybrid Fan Headers detect whether the cooling device uses PWM or Voltage mode and automatically switches settings accordingly.Supports up to 2 amps with built-in overcurrent protection—a must for high-end high current fans.New Smart Fan 5 SoftwareChoose 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 FansEach fan can be customized to operate at different speeds according to any defined temperature source input (except the CPU fan).Fan CurveCustomize fan curves based on specific temperatures with the intuitive graphical UI.Enhanced BIOS InterfaceThe enhanced BIOS interface also has the advanced features seen in the Smart Fan 5 UI, such as: the ability to set triggers based on different temperature sensors on the board, fan curve definition and the temperature interval setting, which can prevent fan rotation noise caused by sudden temperature changeâ€â
