Ideal for power supplies, networking devices, and electronics, these adapters offer a clean, durable solution with easy pin swapping for compatibility. Sold as a pair, they provide a professional, plug-and-play upgrade for your cooling setup. ## 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: 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. Review: Exactly as described, works great, fast shipping. ## Features - Sold as a 2-pack set, these adapter cables allow you to connect 3-pin and 4-pin PC fans to mini 2-pin JST XH 2.5/2.54mm headers, suitable for use in power supplies, networking devices, and other electronics utilizing this connector. - Connector Specifications: Features a 2-Pin Female Mini JST XH Connector (2.5/2.54mm pitch), with Pin 1 designated for Positive Voltage (Red) and Pin 2 for Ground (Black), the most common wiring configuration. - Compatibility Check Required: Given the lack of standardization for XH 2-pin fan connector wiring, some users may need to swap the pins on the mini connector for proper functionality. - Professional Build Quality: RoHS compliant with all-black connectors and high-density PET sleeving, these cables offer durability and a clean look with reduced wire visibility. - Total cable length (including connectors): 4.0 inches (10cm) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B083CRN5L6 | | Best Sellers Rank | #68,152 in Computers ( See Top 100 in Computers ) #206 in Adapter Gender Changers | | Brand Name | CRJ Electronics | | Cable Type | Fan | | Color | Black | | Compatible Devices | Printer | | Compatible Phone Models | No Compatible Phone Models | | Connectivity Technology | 2-pin Mini JST XH | | Connector Gender | Male-to-Female | | Connector Type | 2-pin Female Mini Fan Connector (0.984"/2.5mm Pitch, Xh-style) | | Customer Package Type | sealed anti-static bag | | Customer Reviews | 4.7 4.7 out of 5 stars (250) | | Data Transfer Rate | 3 Gigabits Per Second | | Ethernet Cable Category | Cat 6 | | Indoor Outdoor Usage | Indoor | | Item Length | 10 Centimeters | | Item Shape | Round | | Manufacturer | CRJ Electronics | | Maximum Voltage | 12 Volts (DC) | | Model | 4052 | | Model Name | Mini 2-Pin XH | | Number of Items | 2 | | Number of Pins | 4 | | Other Special Features of the Product | Braided | | Outer Material | High Density Black Sleeving | | Part Number | 4051 | | Recommended Uses For Product | Aftermarket fan replacements in power supplies, networking equipment, and 3D printers | | Specification Met | RoHS | | UPC | 720355064310 | ## Product Details - **Brand:** CRJ Electronics - **Cable type:** Fan - **Compatible devices:** Printer - **Connector type:** 2-pin Female Mini Fan Connector (0.984"/2.5mm Pitch, Xh-style) - **Special features:** Braided ## Images ![CRJ Mini 2-Pin Fan Adapter Cables (2-Pack) - 4-inch (10cm), Black Sleeved - Connect 3-Pin/4-Pin PC Fans to Mini 2-Pin JST XH 2.5mm Headers - Image 1](https://m.media-amazon.com/images/I/71In1UeO2sL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***G on 5 August 2025* I bought this to install a Noctua NF-A12x25 (4 Pin) to my GE Opal 2.0 (2 Pin).
