Noctua NA-FC1, 4-Pin PWM Fan Controller (Black)

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!

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...

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.

Reduced fan noise from annoying to almost nothing.

It meets my high standards. I also paired it with the Noctua NA-FH1, 8-Channel Fan Hub. I have been a happy user of Noctua products since 2008.

Had a noisy Lenovo AIO system fan. Cleaned fan and renewed the thermal paste. Still noisy,. So added this sound reducer inline to the fan wires. Fixed the problem. Only issue was the fan connectors were miniature 4pin PWM and the Noctua has normal 4pin PWM connectors. Solution : buy a pack of these. https://www.amazon.co.uk/gp/product/B08732SVX9/

For people with very specific needs, this product is for you! I needed to control my two PWM pumps but didnt want them to change speed according to what my motherboard wanted to do and this did just the job. It also allows you to connect it to the motherboard to apply a percentage change to the PWM signal and a zero rpm mode too. The package includes a splitter, extension and a cable to connect to the motherboard and power. Good quality instructions are provided too, overall well worth the money!

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.
