## Overview

The CRJ Micro 4-Pin GPU Dual Fan Adapter Cable is a premium 6-inch sleeved cable designed to connect two 3-pin or 4-pin PWM fans to a single micro 4-pin GPU fan header. Engineered for modern graphics cards, it offers a stealthy all-black look and ensures precise RPM monitoring for optimal cooling performance. Ideal for aftermarket GPU cooling mods and AIO setups, this adapter delivers reliable, clutter-free fan connectivity trusted by enthusiasts and professionals alike.

## Description

This adapter cable allows your to connect standard fan header devices to your graphics card. Most graphics cards use a proprietary mini 4-pin connector for their fans but the electrical connection is identical to traditional 4-pin PWM enabled fans. This cable is especially ideal for use in graphics cards modified with an AIO cooler where the nearby fan and pump can connect directly to the graphics card. One important thing to highlight is that not all connections in a fan splitter can be split. Pin 3 (RPM tachometer) is the signal that is generated by the fan (or pump) and sent back to the fan header for software RPM monitoring. This signal cannot be split to multiple fans as it would cause inaccurate RPM reading. Please take note which can connector has the 3rd pin as it will be the primary device sending the RPM signal back to your graphics card.

Review: Have been waiting to try and hook up a small PMW fan to my series s just to see how it would work. The fan header on Xbox series X/S’s is a 4pin micro GPU style plug. The CJR splitter works perfectly but I did have to cut the end off one of my noctua 4pin fan extensions and solder the male end to the stock series s fan so I could simply plug into the CJR splitter, went with a noctua 40x10mm PMW cooling fan for this set up and the series s has no issues powering stock exhaust fan and the noctua fan! No usb wires ran all over the exterior, noctua fan starts, revs up, revs down and shuts off as stock fan does with the PMW controls. Was a bit tricky getting the splitter and extra wires tucked into mobo shell but got it and have two 3-4 hour gaming sessions down with no issues. The CJR splitter is very good quality, sturdy plugs and all pins were nice and secure on all ends. Would buy again and recommend!
Review: Natürlich ist der Preis viel zu hoch. Aber im Gegensatz zum Konkurrenzprodukt für 6€ von Gelid rutschen die Lüfter Kabel nicht von selber wieder raus. (Noctua Redux in meinem Fall).

## Questions & Answers

**Q: is it safe to plug an aio to the gpu fan header using this ? planning on a g12 setup**
A: We have not received any issues from customers using the cable in this configuration, but there are a few things I'd like to note. First is that most of the AIO pumps are 3-pin and will operate at full speed with this cable (GPUs only support PWM for speed control) which is ideal since they're usually quiet even at full speed. We recommend using the fan connector on this cable with the omitted 3rd pin. The reason for this is that the 3rd pin is used for tachometer RPM feedback being sent back to the GPU. Splitting it across multiple fans leads to inaccurate RPM values. The fan connector with the full 4 pins should be used for your fan, either for the VRM fan on your G12 (which is often upgraded to a 4-pin PWM fan for fan speed control for this reason) or the radiator fans.

**Q: Does this work with the rtx series gpus?**
A: Depends on which card. Some of the brands use 12pin(?) connectors that double as rgb and fan headers, others separate the 2 plugs. This worked for my Gigabyte 2080 Super Gaming OC

**Q: Just to be sure, this cable controls both ends via pwn but one of them doesn't have the rpm speed control pin right?**
A: You're exactly correct. Both fans will receive the same PWM signal and thus will operate at the same % speed. Unlike all the other pins, the RPM tachometer (pin 3) is the only wire where a signal is being sent back to the GPU. Sending the signal from both fans would result in an inaccurate RPM reading. All properly designed fan splitters in general also follow the same practice of leaving just one fan connector with the RPM tachometer wired.

**Q: Using with NZXT G12. How would this connect? Rad fan to this adapter and just plug into any sysfan and it reads gpu temp? How does it know gpu temp?**
A: This connector goes directly to the gpu, the Temps are read from the card through the pcie to the board not from the fan connectors. Connecting like this would allow the rad fans to be controlled by the gpu just like the stock fans would, however you might want to see if it's better to have the fans or the aio controlled by the gpu. There should be plenty of forums discussing the g12 use on GPUs.
