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

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.

Using with 12v fan to silent a very noisy network switch. Works great and has been working great for over a month now, no issues and good build quality.

Basically I purchased a little desk on Amazon so I could use my gaming laptop on the couch. The little desk had a cheap fan. I upgraded to a Noctua Fan and needed a way to power that fan by USB. Everything worked flawlessly. Ive only had it a short while so Ill update this review if it dies prematurely since I will be using it practically every day. I was surprised this product even existed but Im glad it does!

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.

Tested out a few fans and a pump with this 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.

Im using this to add a little more airflow for the PS4 Pro exhaust. With a 120mm fan, the noise is quieter and less distracting than the PS4 alone when the fans would spin up high.

Ive pugged this into several different charging blocks. Works great, awesome for testing fan motors. I bought it to use in a soldering vent setup, keep using it to test computer fans.

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.

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.
