Intelligent fan control design. Achieve fan silence. You can map any fan to stop completely when temperatures drop below a specified threshold. Which fan stops, based on readings from which sensor, and at what temperature - all of it can be customized to your liking. Audio noise guard. Gigabyte motherboards feature an audio noise guard that essentially separates the board's sensitive analog audio components from potential noise pollution at the PCB level. LED trace path lighting Illuminates to show the separation of the PCB layers. Smart Fan 5. With 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. Hybrid fan pin headers. Assume complete control over your liquid cooling setup! Hybrid fan headers can automatically detect the type of cooling device whether it be fan or pump with different PWM or voltage mode.
