Works great for my situation.
I have an Alienware Aurora R16 that I wanted to add an additional intake fan to. However, the manufacturers didn't bother including the extra fan header for me to connect one. I didn't want to try attacking my motherboard with a soldering iron, so I got this instead. It has two different connectors, one 4-pin and one 3-pin. The 3-pin connector still has a PWM signal so the fan that's connected to it still spins at a controlled speed. The missing pin is a tach signal which is used for reporting RPM (if the BIOS receives two tach signals from the same header it might freak out). This works great if you're adding another fan to your case but don't have enough headers on the motherboard to connect one to. The package contains two 4-inch long (10 centimeter) braided cords, so I didn't have to worry about the cable length of my new fan.

Two Fans, One Connector, Zero Problems
These do what they‘re supposed to. I had more fans in the back of the case than there are connections on the motherboard. These adapters fixed that. Seems like they’re well made and they work OK.

Does the job
These do the job, which is to split power between computer fans. Things report correctly, both get power. Air moves. Good to go.

A split shorty when you need one
Thes splitters are well constructed, with the sheaving and end heatsink termination. They mate easily and the connection is firm. The short length helped with the general cable layout so that there wasn't a lot of tiebacks. Everything you could want in a simple fan cable.

La calidad esta exelente mas sin embargo dice que es de 4 pines y solo un el conector macho y un conector son de 4 pines, y el otro conector es de 3 pines, se supone que todas las conexiones deben de ser de 4 pines

Works very well, both fans that are connected to it are PWM controlled as confirmed in BIOS.

Cable Matters has proven to me to be a reliable source of well-made cables and adapters, and these Y-splitters are no exception.
