CRJ Full Speed 12V Voltage Step-Up USB to 3-Pin and 4-Pin PC Fan Sleeved Power Adapter Cable

Nice build quality, looks good, does its job so far. I used it to power regular case fans in my network cabinet. Much quieter than the muffing fans now.

I got this product to use an extra 140mm pc fan on top of my Xbox Series X. This adapter provides 12v and the fan runs at full speed which is ideal for me. The Xbox is much cooler to the touch and I feel better than the internal parts are cooler too. I used an extra USB wall adapter which provides 2 amps at 5/12v.

This was exactly what i needed to repurpose an old tower desktop fan. The fan was still great, it just needed that bridge from 3-pin to USB. That being said, as everyone mentioned, this is just a two pin setup. But the fans ran as soon as I hooked them up and plugged them in to a USB outlet or a plugin adapter. This will run the fans at full speed and you will get a fair amount of breeze. Perfect for how i wanted to use this to cool additional electronics.

I needed a 120mm fan for my Intel NUC. I 3D printed a custom case and all, but needed a way to power the fan. This works perfectly!

Ordered a 5v cord first time.. This works great for the higher RPM computer fans-- in ANY type of build. ANYTHING you could need one for.

couldnt use did not receive working item

Duha , fans appear to be spinning at full speed

I use a portable usb battery and one of my old computer fans with this cable to cool the inside my costume helmet. It works great.

First of all, it is important to know not to aim a fan so it is blowing at the exhaust of the PS5, if youre setting up a fan behind your PS5, have it blow the air away from the PS5. Youll probably want to set up your PS5 settings so it only supplies power to the USB port while the PS5 is on, that way the fan isnt running 24/7 while your PS5 is turned off.

This is exactly what I wanted and exactly what I expected. Im using this to power a case fan that I no longer need and use for other purposes.
