You can adjust the cable to 7v by crimping the internal pin on the molex, removing it and inserting it into the opposite farthest hole—so you added a pin on both sides. Or you can purchase a pre-made version.

The Molex Adapter lacks PWM functionality; it only works with fans that support PWM. Consider using a fan controller or a fan limiter.

This cable, when added, allows fans to operate at 7V with approximately 55% reduced speed.

The Molex Adapter lacks PWM control; it only works with fans that support PWM. Consider using a fan controller or a fan limiter. I resolved the issue by connecting it to the CPU fan header.

Where is the connection for your CPU fan located?

Where is the CPU fan connected in the first port with four pins on the adapter?
