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

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.

Duha , fans appear to be spinning at full speed

Needed this to power a 2pin fan and i had no issues, quality cable!

couldnt use did not receive working item

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

Took off side panel of PC to vaccuum and blow out. The side panel fan connector came off...and could not find it. It was a 3 or 2 pin male connector. This inexpensive connector with 3 pin female went into an open USB port on back of PC. Came through the side panel back left corner, not drilling required. EZ solution, and the original an still works, so returned the fans I ordered.

Works perfect, no complaints here

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.

Working pretty good with my 200x200 cooling fan (12V, 0.42A)

Works as designed (regulates all input voltages to 12V). however did not meet my need as i hoped it would be proportional to input voltage. My mistake not mfrg.
