The fan headers are not quite all the same, most of them are four pin fan headers that can work with both three and four pin fans.
IMO, since you don't have any fan control for the Chassis 3 fan with Fan-Tastic tuning, it is not missing by mistake. The Chassis 3 fan header on your board seems to be the same as the Power Fan connectors on other ASRock boards.
Are you using Fan-Tastic Tuning in the BIOS, in Windows with A-Tuning, or both?
The Fan-Tastic tuning in A-Tuning has a Fan Test button for each of the fans it controls. That runs the fan from its highest to lowest speed, and shows the RPM vs speed % setting in Fan-Tastic Tuning. Did you run the test for each fan?
What is the exact model of fan you are using on the Chassis 2 connector? Does it have a three or four wire connection?
All fans are different regarding their highest and lowest speed, what voltage they need to begin spinning, how much power they use, etc. There are very few standards about fan performance and speed. That means a few fans can have such unique operating characteristics that they need special adjustment or configuration to be controlled as you desire.
