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

I bought this to use with a 12 volt dehumidifying telescope fan. It works as expected and the fan runs at full speed.

Am using this to power a Noctua 120mm case fan to provide active cooling for my ASUS AC2900 Router. Works flawlessly. Couldnt be happier and am picking up another to have in my equipment arsenal.

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!

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.

Works perfect, no complaints here

Had to use to power main cooling fan on PC when the water cooler control board failed.

Very nice product if you are trying to hook up a case fan through USB. Loved the braided cable on this one, and it works as intended! Not much else to say. 10/10

This is great!

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.

Does what its advertised to do, tested on PS3. Was purchased to power up a 140mm PWM fan that is going to move air towards exposed SSD heatsink on PS5. Fan started without any issues when used PS3 USB ports, so far so good. No build quality issues observed on delivery. Will later test if it works with laptop ports. Also performed well in combo with a fan speed controller attached in chain towards the fan. Product recommended.
