Introduction
This manual provides essential instructions for the installation, operation, and maintenance of your Lian Li Hydroshift LCD All-In-One (AIO) liquid cooler. Please read this manual thoroughly before installation to ensure proper setup and optimal performance of your cooling system. The Hydroshift AIO is designed to provide efficient cooling and a customizable visual experience for your PC.
Setup and Installation
Proper installation is crucial for the performance and longevity of your Hydroshift AIO cooler. Ensure your system is powered off and disconnected from the power source before beginning installation.
Component Overview
The Hydroshift AIO includes a radiator with pre-installed fans, a pump block with an integrated LCD screen, and tubing. The unique side-mounted coolant pathway integrates cooling tubes with the radiator for a streamlined appearance.

Mounting the Radiator and Fans
- Identify an appropriate mounting location within your PC case for the radiator. Common locations include the top, front, or rear of the case, depending on radiator size and case compatibility.
- Secure the radiator to the case using the provided screws. The pre-installed fans should be oriented to provide optimal airflow (intake or exhaust) for your system.
- Ensure the cooling tubes are oriented upwards from the pump block for optimal performance, as recommended by Lian Li.

Installing the Pump Block
- Apply thermal paste to the CPU's integrated heat spreader (IHS) if not pre-applied to the pump's cold plate.
- Carefully place the pump block onto the CPU, aligning it with the mounting holes on your motherboard.
- Secure the pump block using the appropriate mounting hardware for your CPU socket (Intel or AMD). Tighten screws evenly in a cross pattern until snug.
Cable Connections
- Connect the pump's power cable to an available SATA power connector from your power supply.
- Connect the pump's 4-pin PWM cable to the CPU_FAN or AIO_PUMP header on your motherboard.
- Connect the fan cables to the appropriate fan headers on your motherboard or to a fan controller.
- Connect the USB cable from the pump block to an available internal USB 2.0 header on your motherboard for LCD control and monitoring via L-Connect 3 software.
Operating Instructions
Once installed, the Hydroshift AIO provides real-time monitoring and customizable effects through its integrated LCD screen and companion software.
2.88IPS LCD Display
The pump block features a 2.88IPS LCD screen that displays critical system information such as CPU temperature, CPU load, and coolant temperature. It also supports dynamic effects and multiple themes.

L-Connect 3 Software
To fully utilize the features of your Hydroshift AIO, download and install the Lian Li L-Connect 3 software from the official Lian Li website. This software allows you to:
- Customize the display content and themes on the 2.88IPS LCD.
- Monitor hardware information in real-time.
- Adjust fan speeds and pump performance curves.
- Control RGB lighting effects on the fans.
Maintenance
Regular maintenance helps ensure optimal performance and extends the lifespan of your AIO cooler.
- Dust Removal: Periodically clean the radiator fins and fan blades using compressed air or a soft brush to prevent dust buildup, which can impede airflow and cooling efficiency.
- Cable Management: Ensure all cables are securely connected and routed away from moving parts or heat sources.
- Visual Inspection: Occasionally check the tubing for any signs of wear, kinks, or leaks. While AIOs are sealed systems, a visual check can help identify potential issues early.
Troubleshooting
If you encounter issues with your Hydroshift AIO, refer to the following common troubleshooting steps:
- No Display on LCD:
- Check if the USB 2.0 header cable from the pump is securely connected to the motherboard.
- Ensure the SATA power connector for the pump is properly connected to the power supply.
- Verify that L-Connect 3 software is installed and running correctly.
- Fans Not Spinning or Poor Cooling:
- Confirm that all fan cables are securely connected to their respective headers.
- Check fan speed settings in L-Connect 3 or your motherboard's BIOS.
- Ensure the pump is receiving power and is running (you may feel a slight vibration or hear a faint hum).
- Clean any dust buildup on the radiator and fans.
- High CPU Temperatures:
- Verify that the pump block is securely mounted to the CPU and making good contact.
- Ensure adequate thermal paste application.
- Check fan and pump speeds in L-Connect 3.
- Confirm proper airflow within your PC case.
