Engineered for professional-grade durability and compatibility with power supplies, networking devices, and 3D printers, these RoHS-compliant cables offer a clean, reliable solution for aftermarket fan replacements, eliminating the hassle of splicing while ensuring a neat, efficient build. ## Description Sold as a 2-pack, these adapter cables allow you the ability to connect 3-pin and 4-pin PC fans to a mini 2-pin fan header. This cable is ideal for aftermarket fan replacements in many devices such as power supplies, networking equipment, 3D printers, etc. It is important to verify that this 2.5mm pitch XH-style 2-pin connector is compatible with your device as there is also a less common 2.0mm pitch PH-style 2-pin connector found on some devices which this cable is not compatible with. A quick visual check confirming that this cable has the same 2-pin connector as your original device will be sufficient. On the mini connector side this cable is wired for Pin 1 as the positive voltage (red) and Pin 2 as the ground (black). Some users may find that their device does not use this wiring arrangement and will have to swap the wires. Pull back the sleeving and use an instrument (small flathead screwdriver, pen, etc.) to release the pin retention clips and swap the pins. Review: Works to install a pc fan to GE Opal 2.0 - I bought this to install a Noctua NF-A12x25 (4 Pin) to my GE Opal 2.0 (2 Pin). It worked great, no modifications needed. It was worth buying this instead of dealing with the hassle of splicing. It is also a good length, combined with the fan cord to connect it to. This should work with most circuit boards to install pc fans. Overall its a great buy and looks like its a good cord.
