The NA-SC1 Sx2 is a set of two NA-SC1 3-way fan splitter cables that make it possible to power and control three fans through one fan header. By connecting the second triple splitter cable to the first, a total of five fans can be powered and controlled simultaneously. The NA-SC1 cables also feed the RPM signal of the fan on the first output connector back to the input connector so that PC motherboards or other fan controllers can read out the fan speed. The NA-SC1’s 4-pin connectors are keyed to prevent misalignment and compatible with both 4-pin PWM and 3-pin fans. While 4-pin fans can be controlled through PWM, the speed of 3-pin fans can be adjusted using voltage control. Thanks to the high-quality black fibreglass silicone sleeving, the NA-SC1 cables are ideal both for use in PCs and for home or multi-purpose ventilation applications. Caution: Some PC motherboard fan headers only support up to 1A/12W (check your motherboard manual). When using the NA-SC1 cables in PC environments, make sure that the combined current/power draw of the connected fans does not exceed this value!
3-way splitter for PC and other applications
The NA-SC1 splitter cables not only come in handy when building or upgrading PCs (e.g. if you want to control the fans on your 360mm radiator through a single header or if you add extra case fans and don’t have any free headers), but also in home and multi-purpose ventilation applications such as when powering several fans on a heating radiator through a single NV-PS1 power supply.
PWM control and RPM monitoring
The NA-SC1 1-to-3 splitter cables forward the PWM signal for speed control from the input connector to all 3 output connectors. They also transfer the RPM speed signal of one fan (output connector 1) back to the input connector for speed monitoring through the motherboard or other fan controllers (due to the signal specifications, only one fan per port can be monitored).
4-pin connector
The NA-SC1 cables feature a 4-pin connector that works with both 3-pin and 4-pin PWM fans. As such, the cables are fully compatible with all current Noctua 5V, 12V and 24V fans as well as many third-party models. Additionally, thanks to the keyed design of the connector, there is no risk of misaligning 3-pin fans.
High-quality black sleeving
The NA-SC1 cables come with Noctua’s signature braided fibreglass sleeving with silicone coating that is highly resistant against mechanical wear as well as heat and flames (up to 200°C, UL 1441 certified). As such, the NA-SC1 cables are suitable for use in critical applications and harsh industrial environments.

My new motherboard only has 4 fan ports, making it impossible to connect the 6 fans I installed on the case. This splitter made connecting everything so easy and very minimalistic. Gets the job done, I recommend it

Exactly what I needed to add another fan to the cooler! Simple but effective!

It works and feels more robust than stock ones that come with your case. I think that they look a bit better as well. Not much else to say.

High quality splitter for my PWN fans. Easy to install and perfect if you want to split more fans. The length is perfect to do its job. I recommend also getting their NA-SEC1 4-pin extension for better organization. Great value and I feel it’ll last a long time.

He conectado tres ventiladores Noctua NF-P12 redux-1700 PWM a un único conector de la placa base usando estos adaptadores y funcionan los tres sin problema. Mucho más limpio que usar un hub de ventiladores.

Très bonne qualité de fabrication.L'autre câble du même type mais de marque inconnu, je n'arrivais même pas à enfiler les câbles car la finition des pins était mauvaise.Là c'est impeccable et ça ne bouge pas une fois clipsé.Seul défaut un peu court mais ça peut aussi être une qualité selon le boitier et le montage.La régulation 3 en 1 des ventilateurs en pwm fonctionne parfaitement.

Were a must to install the six 140mm Noctua fans I have as side intake and bottom intake. If you’re a new/first time builder like me, these are a must since Noctua doesn’t have a “daisy chain” model with limited pwm headers on your motherboard. Very high quality, and adequate length given that the fans come with extensions. Can’t go wrong with Noctua, great value and high quality!

These are great if you have some standard fans and not a lot of headers.Issues come up if your fans don't have long cables or if you need a little more clearance to plug the fan into the header as these split right off of the plug.Both sets I got have good wiring unlike other similar splitters that I've bought in the past.
