The Gigabyte GA-B250M-DS3H comes with hybrid fan pin headers that can automatically detect the type of cooling device whether it be fan or pump with different PWM or Voltage mode. These headers support up to 2 amps with built-in overcurrent protection--a must for high-end high current fans. The 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 change--all without having to load Windows.
