Full Speed 12V Voltage Step-Up USB to 3-Pin and 4-Pin PC Fan Sleeved Power Adapter Cable(Pack of 2)

I bought this Gebildet USB fan adapter specifically to power my Noctua NF-S12B redux-700 fan. As you know, these Noctua fans are fantastic for quiet operation, but they're 12v fans and USB ports only put out 5v. This little adapter solves that problem perfectly. Plug and Play Simplicity This adapter is incredibly easy to use. It plugs into any standard USB port and then connects directly to your 3-pin or 4-pin PC fan. No muss, no fuss - just instant power for your fan. Powers Noctua Fans Perfectly I can confirm that this adapter delivers the full 12v needed to run my Noctua fan at its intended speed. This means you get the maximum airflow and quiet operation that Noctua fans are known for. Great for Various Needs While I use this with a Noctua fan, this adapter is a great solution for anyone who wants to run a 12v fan from a USB port. It's perfect for cooling down electronics projects, game consoles, or anything else that could benefit from some extra airflow. Overall Impressions This Gebildet adapter is a lifesaver for anyone who wants to use a 12v fan with a USB power source. It's simple to use, works flawlessly, and lets you enjoy the full performance of your fan. Highly recommended!

Really great USB to 4 pin fan headers for PC fans. I have used these to connect some unused Noctua fans so I can use them to blow air onto my Mac-mini servers running linux. The servers have USB-A ports which I use to power the fans. USB-A is pretty much everywhere still - so great to have around. I imagine these can be used for other things too, like lighting/RGB perhaps? Good build quality, price and easy to use.

Works as expected. Good value.

Simple solution to power 12v PC fan. Single speed as advertised.

Used this to power an old PC fan to cool a network rack.

just what i needed! as a pc builder i have lots of spare fans, ive used these to cool down settop boxes/routers etc. BARGAIN!

I had some 12v led lights for my arcade machine. Instead of spitting the fan socket in the pc it now runs from usb.

5v to 12v ,4A they work

Gewoon goed

Funzionano benissimo e sono adatti alle mie esigenze

Certains se plaignent de produit inaproprié; moi, aucun soucis avec celui ci. Le ventilateur tourne à sa vitesse normale; mais c'est un faible puissance autour de 0.1A; un petit dongle de ce genre n'est probablement pas fait pour du 0.5A. Ca semble juste produire correctement du 12V.

I almost forgot I bought these, they've been so reliable. They run from a couple USB-A power adapters to some Noctua fans that cool some SFP+ modules in my network. Haven't had a single problem with them, ever.
