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. It automatically detects impedance of your head-worn audio device, whether earbuds or high-end headphones to provide optimal audio dynamics - preventing issues such as low volume and distortion. Sulfur compounds in the air can penetrate tiny onboard resistors creating chemical change and causing these resistors to open or short. If either of these occurs the motherboard will fail to function. By equipping resistors with an anti-sulfur design GIGABYTE gives Ultra Durable motherboards an amazing meaning. Onboard LEDs indicate if a malfunction is occurring, allowing users to quickly diagnose which major component is malfunctioning so they may take action promptly.
