NA-FC1, Compact PWM 4-Pin Manual Fan Speed Controller

I never knew these existed. My fans are 4 pin so they fitted first time. If you have 3 pin fans you’ll have to do your own research.What a great piece of kit! I have managed to reduce my supersonic blast off server to almost acceptable volume levels now.Well worth buying

Have you ever had the problem of wanting more fans into your pc, and havent enough headers on your motherboard, and if you plug the fans directly into a molex/sata lead from your powers supply they will spin full speed all the time without any way of controlling them? This little device solves that problem right away! easy to install, set up, and makes your PC a lot quieter! yes you have to pay for this, but Im sure that it will prolong the life of your fans, as you can significantly reduce the RPM and workload of them! Made by Noctua, to me (and countless others) are one of the best, if not the best company for PC fans/cpu coolers, you are getting a useful piece of equipment that is very well built, and is a must for anyone who has cooling issues! The control unit, is small, well hidden and takes literally minutes to install and set up! Rather than "overload" each CPU header with multiple "Y" connectors, I can have piece of mind that I know that my motherboard isnt being overloaded! Its ideal to use with Noctuas' Industrial fans, as they use more power than the "normal fans". I can control 3 of the 3000rpm fans so you can not hear them! cant recommend this device enough, should of got one years ago!

Exactly what I needed to slow down my 5 fans

To have easy access to fan control expect to have more cables than desired outside the PC case, will look a bit messy, (minimum 2 long extensions cables will be outside case, you will need to buy separately) Or more visible with what comes in box, see photo, used velcro tape to mount. Works well, simple to use.

Excellent little device. Works exactly as described. Lowered rpm of my Noctua NF-A8 5V PWM fan to a point where it still provides plenty of airflow to my 3.5 external sata enclosure while making the fan completely silent. Very happy.

Sometimes, particularly if you have a non-standard fan configuration, or if your motherboard doesn't support PWM speed control, you may want to step in to manually control your fans' speed. the options here are: 3-pin fan connector - you can set an absolute fan speed; 4-pin connector - you can step down the speed of your fans while leaving them under the control of your motherboard. There's also a "non-stop" button which prevents the fan from spinning down completely.It's very easy to fit this little device electrically (it comes with suitable cables), although you need to find somewhere in the case to place it. It does the job really well, and although it's no substitute for a BIOS with proper fan control it's a good substitute if you're confident you know what fan speeds you actually need.Noctua make lovely cooling fans. This little device is hardly as lovely, but it is very practical.

Used this to control a vent fan I added to a PC desk which has the PC in an enclosed (but open backed) cupboard.Works well and allows you to quiet the fan down as it's not really needed to run as full RPM for my use case (just needs to create some negative pressure to draw air from the back of the cupboard).The wire connector is prone to falling out though and could do with a clip mechanism to keep it attached...

Great speed and cooling controller for their fabulous range of fans!

Good and practical; controlling a 3000rpm exhaust fan.

versatile, pouvant s'adapter aux différentes situations possibleà partir du moment où l'on monte soi-même sa touret qu'on a des exigences de silence pour ses ventilateurs.Permettant de s'adapter à tous les cas de figure rencontrés

Very useful product. Really liked it 👍👍

The Noctua NA-FC1 PWM fan controller is an outstanding addition to any setup where fine-tuned fan control is essential. As expected from Noctua, the build quality is top-notch, and it performs exactly as advertised.Pros:Excellent Build Quality: Noctua consistently delivers durable and well-designed products, and this controller is no exception. It’s solid and compact, perfect for managing fan speeds in any setup.Precise Fan Control: The NA-FC1 allows for smooth adjustments to fan speed, letting me dial in the exact balance between cooling and noise for my system. It’s simple yet very effective.Minimal RPM Button: A standout feature is the button that, when pushed, ensures the fans maintain a minimum rotation speed. This is especially useful for keeping a quiet but steady airflow in the system without letting fans stop completely.Overall: If you need reliable and precise fan control, this Noctua controller is a fantastic choice. With its sturdy design and thoughtful features like the minimum RPM button, it’s an excellent tool for quiet, efficient cooling. A solid 5 stars for a simple but well-executed product.

i use this to control my PWM fans in a server cabinet. Does precisely what it says and controls my 3 cabinet fans with no trouble and the rande of the knob is wide enough to allow for rather precise speed control. THis is a genuine noctua, so not cheap, but a great value for money - no buzz, works great, and I was shocked how tiny it is - the size of a pack of chewing gums - it is super tiny!
