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

Works perfect with the Noctua NF-A12x25 PWM fan, I can now use the dial to increase the fan performance to low or high or in-between. This gives me the benefit of picking the right noise I want and if I do require a bit more better cooling performance I can increase the dial to push the fan more better but this comes at the price of more noise.Its expensive, but its the best fan controller via USB on the entire market, the others have cables that do similar are chunky have boxes and power inputs but this ones slim and simple and just works.

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 SimplicityThis 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 PerfectlyI 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 NeedsWhile 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 ImpressionsThis 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!

Works as expected. Good value.

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.

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

Used this to turn my 2nd Noctua AF14 fan into a desk fan, this allows it to run at full speed and the switch is also very useful. If you are using it for this purpose, make sure to get a fan grill, I 3d printed mine so i don't know how easy they are to source.

Works nicely with a couple of PC fans that I’ll be installing on the back of a media cabinet to help exhaust the warm air from the AV receiver and other equipment.The beauty of the built in voltage adjuster is the fans can be turned down to make the minimal amount of noise whilst achieving the air flow goal.The cable could perhaps be a little longer but that’s easily solved with a USB extension lead and I imagine for most applications they’re fine as they are.

This item is very poor quality, one of the solider joints was disconnected when i received the item. I had to repair this my self.If you dont have a soldering iron dont bother buying.8.99 uk is way to much for this quality.
