SuperMicro X11SDV-12C-TLN2F

Hi, I would like to know how to manually set fan curves if possible. My PWM fans don’t run at a high enough RPM, if possible I would like them to match the CPU FAN RPM. I really hope this is possible. Also, i am not sure which connectors I should be using on the motherboard, FAN1 is CPU, so FAN2 or FANA for chassis fans, can i split the fans between 2 and A, or should i gran a fan splitter to have the mall on the same fan header?
