Know before you buy
No. Because this adapter draws power directly from the Molex connector on your power supply, the fans will run at their full 12V speed at all times and cannot be adjusted via PWM software.
Yes, the connectors are designed to be compatible with both 3-pin and 4-pin PWM case fans.
The cable measures 12 inches (30cm) in total length, which is sufficient for most standard mid-tower PC builds to reach from the power supply to your fan mounting points.
No, this cable is strictly for power delivery. It does not include a tachometer wire, so your motherboard will not be able to detect or report the RPM of the fans connected to this adapter.
The high-density nylon sleeving provides a clean, professional look for cable management while also offering a layer of protection and durability for the internal wires.
