First, that mobo has no way to power and control the RGB lights in a lighted fan, so you need an RGB controller of the correct type to go with whatever fans you buy. Fortunately, several models of RGB fan by Corsair are sold in packs of three that also include the right controller for them. Which model of controller (and how the control changes are made) varies a bit. It appears in all cases that the controller boxes provide power and control to BOTH the fan motors and the lights in the fan frames. In such a case you do not need to make any fan motor connections to a mobo SYS_FAN header, and that may mean there is no automatic fan speed control in at least one case.
You need to get clear which fans you are talking about - there are no Corsair SP120LL fans. They do sell SP120 RGB fans, and the 3-pack comes with 2 boxes - a hub that you plug your fans into and that gets power from a SATA power output from the PSU, and a 3-button box of manual controls for colour displays and fan speed.
They sell the LL120 RGB fans in a 3-pack with two boxes, but different. The set includes that same lighting Hub plus their Lighting Node Pro controller. This latter device connects to a SATA power output from the PSU for power, to a mobo USB2 header and to the Hub. Then you download and use their iCue software utility that communicates (via the USB2 cable) with the Lighting Node Pro box to generate the light display and fan speed control signals by software, rather than by manual butons.
Corsair sells their iCue SP120 RGB Pro fans in a 3-pack with their new Lighting Node Core single box that combines the controller and hub functions into one box. It connects and operates similarly to give you iCue software control using a USB2 cable communication connection.
In all these cases, power and control of both the fan motors and the lighting components in the frames are done by the Control box system supplied with the 3-pack of fans. You do NOT do control of either function of the fans using your mobo headers, so there is no compatibility issue to be concerned about.
