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: Great product and the quality was good. The price was just right. would purchase from the seller again ## 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 | #73,546 in Computers ( See Top 100 in Computers ) #199 in Adapter Gender Changers | | Item model number | 4052 | | Manufacturer | CRJ Electronics | | Package Dimensions | 9.4 x 6.1 x 0.79 cm; 18 g | ## 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).

The price was just right. would purchase from the seller again ### ⭐⭐⭐⭐⭐ Review *by S***K on 7 March 2024* It turns out there are different sizes of two pin connectors on motherboards. There are lots of little fans out there that have a two pin connectors but they were too big / wrong size for what I needed. This little adapter cable fit perfectly. I just had to order a fan that had a three pin connector on it and it fit into the other end of this cable. ## Frequently Bought Together - 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 - Noctua NF-A6x25 FLX, Premium Quiet Fan, 3-Pin (60mm, Brown) - Noctua NF-A14 iPPC-3000 PWM, Heavy Duty Cooling Fan, 4-Pin, 3000 RPM (140mm, Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/397274842-crj-mini-2-pin-fan-adapter-cables-2-pack-4](https://www.desertcart.pl/products/397274842-crj-mini-2-pin-fan-adapter-cables-2-pack-4) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
