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

I greatly underestimated how fast or loud powering a 120mm case fan with this would be. The cable itself isn’t anything special and feels sturdy enough. Most importantly it does what it is supposed to do. So if you need high rpm, high noise, 24/7 fan operation you cant go wrong.

This is probably just a cable with a micro buck boost installed in the cable housing, but its perfect for testing fans and/or using it to power up a spare fan for a desktop cooling device. Only thing Id knock is the price.

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.

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

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

Bought one and it worked well so bought more. All cables are working fine.

This works exactly as it’s described. I added a small cooling fan into the back of my entertainment center to cool my Xbox One X because it was in a rather enclosed space. The USB the three pin adapter allowed my to plug the fan into the back of my tv so now the fan only runs when my tv is on and the Xbox stays cool when I’m gaming. The construction of the cable is a little flimsy and would definitely not be hard to break. The heat shrink has already started to move around on the cable and I only touched it to install it. This would have been a five start review if not for the mediocre construction.

Works well, would be better if it had a dial to adjust speed for PWM fans. The usb plug is large and sticks out when I connect this to my dongle, but overall it works as intended.

This is great!

My son bought this to use with his custom 3d-printed laptop cooler/stand (designed/built/printed himself). He ran two 120mm fans off of it and it worked great. No issues with the USB port or the fans when using the cable.
