can't get to work with asus mobo/corsair fans

[pine-serpent]

i have a asus b460 tuf pro mobo w/ corsair h100 cpu liquid coole with 2 120mm on the rad plugged into the corsair cooler and that is plugged into the cpu fan on mobo. also have 4 corsair rgb fans plus a noctua fan. 2 of the 140mm corsairs are using a splitter plugged into the mobo with 4 pin. 1 corsair is plugged directly into mobo 4 pin. finally last corsair is on splitter with noctua plugged in to 4 pin.

with fan control i can only control the singular corsair plugged into the board directly and the noctua on a splitter. even the corsair split with the noctua isnt controllable. also the cpu fan (which is actually the liquid cooler) is showing like 5000rpm constantly and cant be controled. it is not running at 5000rpm, maybe something to do with the pump? in hwmonitor is also says it is 5000rpm. in icue software the cooler fans are correctly reporting at around 600rpm.

any help getting my setup to work aith fancontrol?
