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

Duha , fans appear to be spinning at full speed

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

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.

This is great!

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.

There are a couple of comments re frail materials/build on this one, while I can see whats being referred to, and yes, the join on the fan connection end could be better finished, I really cant see where this would cause a problem with normal use. After all you should be treating any cabling gently and well. A USB 3 connection fired the PWM12 fan up and it certainly cooled the object(s) in its path!

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.

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.

couldnt use did not receive working item

Tested out a few fans and a pump with this cable.
