Why L-Connect 3 still show "USB not detected" after connection, and why is HydroShift II not detected in Device Manager?

It may be due to lack of power from the connected PWM port. Please enter your BIOS and set the connected PWM port (recommended CPU_FAN or AIO_PUMP or PUMP ) to PWM/DC mode instead of Auto. Make sure to set the port to full speed.

Motherboard Doesn't Read Pump RPM

1.Use the 6-pin power cable. 2.Connect the 4-pin to SYS_FAN (for RPM signal), and the 2-pin to CPU_FAN (to ensure adequate power).

HydroShift II LCD-C – L-Connect 3 Doesn’t Detect Fan RPM

Ensure the power-supplying PWM cable is connected to the motherboard’s CPU_FAN or AIO_PUMP header.

AIO Cooler Bracket Installation Steps

1.Install CPU. 2.Mount water block bracket (notch to the right). 3.Secure screws with screwdriver (notch right). 4.Attach pump head (right to left) and tighten. For full details,please refer to the user manual.
