Total cable length (including connectors): 6.0 inches / 15 cm Review: High quality splitter, works for Xbox! - 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/Sā€™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: Works as intended. - After my second round of ordering since the first order somehow got damaged in transit to me and ended up being returned to desertcart it functions. ## Features - The perfect cable for graphics card aftermarket cooling and deshroud modifications.

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. ## Customer Reviews ### ā­ā­ā­ā­ā­ High quality splitter, works for Xbox! *by 9***R on August 20, 2024* Have been waiting to try and hook up a small PMW fan to my series s just to see how it would work.

It is a quality made cable like the noctua splitter and works great for setting fan curves. ## Frequently Bought Together - CRJ Micro 4-Pin GPU Dual Fan Adapter Cable - 6-Inch (15cm), Black Sleeved - Micro PH (2.0mm) PWM Graphics Card Fan Adapter for Connecting Two 3-Pin & 4-Pin PC Fans - Noctua NF-A12x25 PWM chromax.Black.swap, Premium Quiet Fan, 4-Pin (120mm, Black) - Noctua NF-A9 PWM chromax.Black.swap, Premium Quiet Fan, 4-Pin (92mm, Black) --- ## Why Shop on Desertcart? - šŸ›’ **Trusted by 1.3+ Million Shoppers** ā€” Serving international shoppers since 2016 - šŸŒ **Shop Globally** ā€” Access 737+ million products across 21 categories - šŸ’° **No Hidden Fees** ā€” All customs, duties, and taxes included in the price - šŸ”„ **15-Day Free Returns** ā€” Hassle-free returns (30 days for PRO members) - šŸ”’ **Secure Payments** ā€” Trusted payment options with buyer protection - ā­ **TrustPilot Rated 4.5/5** ā€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/144538113-crj-micro-4-pin-gpu-dual-fan-adapter-cable-6](https://www.desertcart.be/products/144538113-crj-micro-4-pin-gpu-dual-fan-adapter-cable-6) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-06-18*
