CRJ DC Power Supply Plug to Dual 3-Pin and 4-Pin PC Fan Power Adapter Cable (2-Pack)

I purchased this to use on a custom laptop stand I made for my Lenovo Legion 5 gaming laptop. I prefer not using USB for my fan power on my laptop stand because I doesn't take away a port from your laptop and it allows you to run an increased voltage and to vary the voltage to vary the speed of the fans. I am currently running this with a set of Noctua redux 120mm fan and a 7.2v adapter and I gives the perfect fan speed for optimizing quietness and airflow. Also I found that if you get one of those universal multi voltage power adapters that you can adjust voltage and thus fan speed on the fly.

This operates dual cooling fans on top of a home theater receiver. These are powered by a load sensitive switch and has been perfect.

simple. it works

I purchased this cable to install two 80mm fans to an external power supply. The barrel end of the cable fit my "belker" power supply without any additional adapter. This made connecting the fans very easy and straightforward. This is a helpful workaround for the Dell prebuilt I was upgrading which had no case fans, a proprietary motherboard, proprietary power supply, proprietary power connector, and no extra fan headers or molex connectors.

All good

Great if you need to power up fans with ac adapter instead of USB. I used two Noctua fans on a laptop cooler pad powered by an ac adapter and it does the job perfectly.

Works like champs

worked to connect 2 computer fans to one power source
