Question Will my motherboard support a 1 to 4 3pin Y splitter for my case fans?

Aug 27, 2019
I have a Define C TG by Fractal design Case with 2 of their 120mm 3 pin Dynamic GP-12 case fans pre-installed.

Motherboard: Gigabyte Z68MA-D2H-B3

This motherboard has only 1 4 pin sys_fan header on it and I'm currently using a 1-to-2 3pin Y splitter for the 2 pre-installed fans and they're working normally.

I would like to add 2 more 140mm 3-pin Dynamic GP-14 fans to my case, however, since they're controlled by voltage and are not PWM like the 4-pins, I heard that having a 1-to-4 Y splitter for all 4 fans on just one header might overload my motherboard/force it to output too much voltage for 4 fans via one single header.

Edit: The adaptor is Nanoxia 3-pin Fan Female - 4x 3-pin Fan Male

Ask me anything. Whatever extra info you need. Also, my whole build is in my signature.

Is it safe to place the order or do I risk frying my motherboard?
