Can a 3-pin case fan be controlled by MOBO through a fan splitter?

I have an ASRock AB350 Pro4, it has 2 case fan headers (CHA_FAN2 and CHA_FAN3) they will auto detect and allow to control a fan if it is 3-PIN or 4-PIN (PWM). The MOBO only has 2 ports but I have 4 fans. I will need to use 2 fan splitters and will connect the rear fans on one, and front fans on the other. I want to know if using the fan splitter will not allow the fans to be controlled. I am aware that when you use a fan splitter you can not control the fans on the splitter individually, I am fine with that. I just want to be able to control fans plugged into each header. I know this is a hard question but I would appreciate any insight. Thank you!

  1. If I'm understanding your question correctly, the answer is yes. I do it all the time. If the two fans on the same splitter are identical, the RPM shown will be the same for both. But use a splitter that has the tach feedback pin missing from one of the connector ends so there will only be one fan reporting. Example.
