Review on 🔌 RackTeck PWM Fan Splitter Cable 1 to 4: Extension for 3 Pin & 4 Pin PC Case Fans (12 Inch) by Jacob Sriubas

This is a strong rope. Love the quality of the sleeves and haven't had any issues with crooked pins. This cable runs 3 fans and everything is fine. I noticed that all but one of the cables are missing a third wire, as another reviewer did. Although I was a little annoyed, a quick Google search revealed that the missing wires were for the tachometer (RPM sensor). Makes sense, you can't hook up multiple sensors in parallel and expect the computer to figure it out. Connect all 4 wires to whatever fan you think is the most important, as the computer will "see" that one.
