[SOLVED] Need help with case fan splitter

[basketballthebest23]

Hey guys, I wanted to buy these fan splitters in a 2 pack https://www.amazon.com/Rosewill-Splitter-Duplicator-Converter-Adapter/dp/B076HBQTD5/ref=sr_1_2_sspa?ie=UTF8&qid=1548393133&sr=8-2-spons&keywords=case+fan+splitter&psc=1 . And I have a 4 pin connector for my back 2 fans and a 3 pin connector for my front two fans. My question is If these connect to a 4 pin on the mobo, then will it connect to my 3 pin connector on my mobo?

If you connect one 3pin and one 4pin on same 4 pin/3pin header they would both work only in DC mode.

But if the spot on my mobo for the fan is 3 pin and I plug in a 4 pin splitter what will happen? Will the splitter still work?

Yes, it will still work in DC mode instead i PWM mode. If you look at that 4 pin connector you will see that a notch is not in the center but a bit off so it can plug in a 3 pin header.
