## Overview

The CRJ Mini 2-Pin Fan Adapter Cables (2-Pack) are 4-inch black sleeved cables designed to connect 3-pin and 4-pin PC fans to mini 2-pin JST XH 2.5mm headers. Featuring durable RoHS-compliant construction and flexible wiring options, these adapters are ideal for power supplies, networking devices, and other electronics requiring compact, reliable fan connections.

## 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.
Review: Used along with Zalman FanMate and opposite cable to slow down Bitmain AW3++ PS fan. Works Great. - 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.

### ⭐⭐⭐⭐⭐ Worked as advertised and solved my problem.
*by J***N on October 30, 2025*

Worked great. I had to replace a noisy fan in a brand new astro-camera. This adapter allowed me to avoid cutting and soldering - something I would not have relished on a $1500 camera!
