90B Fan error (CPU fan isnt working) on startup but it DO WORK... How to fix?

[Zoxi57]

What is wrong with my system/bios? I have no fan connected in LCfan but I got my 2 fans connected to a split to the CPUfan.. I changed from the AIO cooler to a fan cooler. It cant detect my cpu fan I guess? Becuz I can see the other fans in the bios (rear/front) running normal, but it cant see the CPU fan, why? It sounds like its loud too, I guess it runs on max becuz it cant detect it? Am i missing a cable that can see the cpu fan and temp?  Do I need the cpu fans where the pump was going maybe?
