The pump noise is audible.
The GA II LCD AIO utilizes Asetek’s 8th Gen pump, originally capped at a maximum speed of 2600 RPM. To address the growing demand for CPU heat dissipation, we have unlocked the pump’s maximum speed to 3600 RPM.

We suggest using L-connect 3 build-in pump/fan profile function to set PWM curve, finding the optimal balance between noise and performance. The pump motor operates efficiently at 2200 to 2500 RPM for regular use, maintaining a friendly noise level.
First time installing GA II LCD and experiencing black screen on the pump.

1. Connect the USB type C header to the pump firmly. Ensure it clicks into place without any gap.

2. Connect the USB type C cable directly to the motherboard’s 9-pin USB header.
