I have one of my 3-pin chassis fan connected to the board 3-pin connector labeled CHA_FAN3.
From what is written in the manual it should have speed control but when I go in the UEFI advanced menu under H/W Monitor I can't seem to find Chassis Fan 3 Setting, there are only fan 1 and 2 setting. The manual explicitly states that there should be that setting (pag. 77). I have also checked that Fan 3 is correctly detected by the mainboard.
