Gigabyte APP CENTER has quite a few apps. Smart Fan 5 is a utility within the SIV (system Information Viewer). This utility has many features for setting the fans to cool the system fans. This utility was not working for me and many other users. To-days download has fixed this.
I have done a guided tour for the "Smart Fan 5" utility.
