Support
HDMI 2.1, which is backwards compatible with HDMI 2.0/ 1.4 and offering 48 
Gb/s of bandwidth twice times more than previous generation. This unlocks the 
potential for users to transfer multiple video streams, as well as a native 
cinematic 21:9 ratio (which most movies are shot in), Full HDR and HDCP 2.3 
support, to offer the best visual experience for viewers.

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. 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.

Hybrid Fan Headers
  - 5 Temperature Sensors 
  
- 3 Fan Pin Headers 
  
- All Fan Pin Headers Upgraded to Hybrid Fan Headers 
  
- Interoperable Fans and Sensors 
  
- Intuitive UI for Fan Control

Achieve fan silence. With Fan Stop, 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 temperatureall of it can be customized 
to your liking.


Intelligent Fan Control Design

Hybrid Fan Pin Headers
Assume complete control over your liquid cooling setup! Smart Fan 5 receives 
up-to-the-second information on flow-rate and water-temperature through the 
Hybrid Fan Pin Headers or external thermistor sensorsgiving you absolute mastery 
over your PC.
  - All Hybrid Fan Headers can automatically detect the type of cooling device 
  whether it be fan or pump with different PWM or Voltage 
mode.

New Smart Fan 5 Software
Choose from different modes, Quiet to Full Speed, to match your system usage 
preferences. For each fan or pump, you can use the intuitive fan curve to define 
trigger thresholds and corresponding fan speeds.

RGB FUSION 2.0
With B550 Motherboards, RGB Fusion 2.0 is even better with Addressable LEDs. 
RGB Fusion 2.0 offers users the option to control onboard RGB and external RGB / 
Addressable LED light strips* for their PC build. Already feature filled with 
colors and patterns, RGB Fusion 2.0 are now upgraded to improve the Addressable 
LED support. With external Addressable LED strips, where each LED is digitally 
addressable that users can experience even more patterns, styles, and 
illuminations.
With B550 Motherboards support the external 5V Addressable LED lighting 
strips and up to 300 LED lights. RGB Fusion 2.0 with Addressable LEDs comes with 
new patterns and various speed settings with more to come.

RGB Fusion 2.0 Software
With an integrated intuitive user interface, the RGB Fusion 2.0 provides you 
a better solution for customizing the lighting effects across all supported 
devices. From motherboards, graphics cards to the peripheral products, you can 
personalize your gaming rig with your own style and show off your build by 
sharing the profiles. In addition, the new gaming mode makes the lighting 
effects interactive with selected games to bring you the most immersive gaming 
experience.

Sync with one click

Individual control as you wish
GIGABYTE RGB Fusion APP
Don't just make your PC shine, make it a work of art that friends will envy.
