Review on 💻 12-inch PWM Fan Splitter Cable - TeamProfitcom Braided Y Splitter Adapter for Computer CPU Fans - PC 4 Pin Fan Extension Power Cable - 1 to 4 Converter by Peter Zouhair

Upon further investigation, the missing pins are for motherboard connectors that are not needed in the splitter. Product works as intended, first review below is OLD, READ ABOVE*** 3/4 wires are not making contact. I read customer reviews and decided to take a chance; Take my advice and don't risk it. This is seriously poor quality control. I think the picture should speak for itself *** THE PRODUCT WORKS PROPERLY!
