[SOLVED] Fan splitter.

I ordered this fan splitter from amazon, i was wondering if it was normal that one of the cords have a yellow and the other one doesn’t?

Normal.
The splitter only connects to one fan with the yellow wire.
That way it can monitor RPMs.
If both fans were sending RPM signals it would confuse the software and controllers.
