Ideal for aftermarket fan replacements in power supplies, networking devices, and 3D printers, these RoHS-compliant cables offer durable construction and flexible pin swapping for compatibility, ensuring a clean, professional connection in compact spaces. ## 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. ## 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 | 103,794 in Electronics & Photo ( See Top 100 in Electronics & Photo ) 33,853 in Hi-Fi & Home Audio Accessories | | Brand | CRJ Electronics | | Cable Type | Mini XH to 3-pin and 4-pin fan connector adapter | | Cable type | Mini XH to 3-pin and 4-pin fan connector adapter | | Colour | Black | | Compatible Devices | Printer | | Compatible Phone Models | No Compatible Phone Models | | Compatible devices | Printer | | Compatible phone models | No Compatible Phone Models | | Connectivity Technology | 2-pin Mini JST XH | | Connector Gender | Male-to-Female | | Connector Type | 3/4-Pin Male (Specialized Connector Compatible with 3-Pin and 4-Pin PC Fans), 2-Pin Female (0.984''/2.5mm Tilt, XH Style) | | Connector type | 3/4-Pin Male (Specialized Connector Compatible with 3-Pin and 4-Pin PC Fans), 2-Pin Female (0.984''/2.5mm Tilt, XH Style) Connector type 3/4-Pin Male (Specialized Connector Compatible with 3-Pin and 4-Pin PC Fans), 2-Pin Female (0.984''/2.5mm Tilt, XH Style) See more | | Customer Package Type | sealed anti-static bag | | Customer Reviews | 4.7 out of 5 stars 229 Reviews | | Data Transfer Rate | 3 Gigabits Per Second | | Ethernet Cable Category | Cat 6 | | Indoor Outdoor Usage | Indoor | | Item Length | 10 Centimetres | | Item Shape | Round | | Manufacturer | CRJ Electronics | | Manufacturer Part Number | 4051 | | Maximum Voltage | 12 Volts (DC) | | Model Name | Mini 2-Pin XH | | Model Number | 4052 | | Number of Items | 2 | | Number of Pins | 2 | | Other Special Features of the Product | Braided | | Outer Material | High Density Black Sleeving | | Recommended Uses For Product | aftermarket fan replacements in power supplies, networking equipment, and 3D printers | | Special feature | Braided | | Specification Met | RoHS | | UPC | 720355064310 | ## Product Details - **Brand:** CRJ Electronics - **Connector type:** 2-pin Female Mini Fan Connector (0.984"/2.5mm Pitch, Xh-style) - **Cable type:** Fan - **Compatible devices:** Printer - **Special feature:** 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) ![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 2](https://m.media-amazon.com/images/I/81Pwg9IhB-L.jpg) ![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 3](https://m.media-amazon.com/images/I/71aJip+sXEL.jpg) ![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 4](https://m.media-amazon.com/images/I/71EgZat3BWL.jpg) ![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 5](https://m.media-amazon.com/images/I/71SD-kgDm6L.jpg) ## Available Options This product comes in different **Size Name** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works to install a pc fan to GE Opal 2.0 *by on Reviewed in the United States 5 August 2025* 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. ### ⭐⭐⭐⭐⭐ Great product *by on Reviewed in Canada 3 January 2025* Great product and the quality was good. The price was just right. would purchase from the seller again ### ⭐⭐⭐⭐⭐ Used along with Zalman FanMate and opposite cable to slow down Bitmain AW3++ PS fan. Works Great. *by on Reviewed in the United States 29 September 2020* I can remember quieting down my CPU in the late 90s and it took me a while to find the product, which was a Zalman Fanmate. They weren't made anymore, but I found a bunch used in a lot on eBay. My ASIC miners along with the separate power supply were just too damn loud. They, however, make really great efficient space heaters. If using a proper space heater, they produce about the same heat per watt used, except at full blast, they are too loud for most unless someone enjoys the sound equivalent to a running handheld pistol styled hairdryer. I had found most of the noise to be coming from the cooling fan on the ASIC miner itself. Firmware was able to take care of the fan noise, but also mine at a reduced rate - which is fine for me as full blast, it was too hot for the room. After successfully slowing down the ASIC fans with firmware, I discovered that the PS also makes a somewhat obtrusive noise. It is the Bitman AW3++ PS in particular as the HP 750W Server PS I also had was quieter. After investigating, I found it was a 2-pin connection and this jogged my search for Zalman Fanmates, this item, and also its opposite.I had found that both the "CRJ Mini 2-Pin Male Fan to Standard 3-Pin PC Fan Adapter Cable" and the "CRJ Mini 2-Pin Female PC Fan Adapter Cable 2-Pack" along with the Zalman Fanmate in the middle was enough to slow the fan down to an unobtrusive noise-level. It's not quiet by any means, but now it sounds like I have a space heater running and it keeps my feet toasty since I have these setup below my desk. I'm spending about the same power as if I were running a proper space heater, I get about the same heat and noise-level as a proper space heater, but I get to mine 50 cents of crypto a day. LOL. Still mining at a loss, but would have set up a space-heater anyways.This review is also going verbatim under the other cable. It works for what I wanted it to do - which is insert a 2-pin Zalman Fanmate between the 2-pin built-in fan and the jumper on the circuit board. It fits without electrical or physical modification. I need two Fanmates in there if I want to completely stop the fan, but that's not directly relevant to this product. ## 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.com.au/products/426244491-crj-mini-2-pin-fan-adapter-cables-2-pack-4](https://www.desertcart.com.au/products/426244491-crj-mini-2-pin-fan-adapter-cables-2-pack-4) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-06-18*
