LIAN LI has acknowledged user feedback about power delivery issues affecting some units of the recently launched HydroShift II LCD-C 360 AIO coolers. This issue appears to be caused by some motherboards not supplying enough power through the CPU fan header. LIAN LI has developed a solution and will be updating the HydroShift II LCD-C 360 to address the issue. Please see the full notice from LIAN LI below.
Revised Solution (Updated 10-6-2025)
To ensure user safety and ease of installation, we will no longer offer PCB replacements, as the process may be difficult for some and carries potential risks. Instead, we will be providing a new 6-pin power cable that offers a safe and straightforward solution for users who can't adjust their BIOS settings only.

Important Notice
Since the launch of the HydroShift II LCD-C 360 Series, we’ve received valuable user feedback regarding a few issues. Below are the findings and corresponding solutions:
LCD Screen USB Not Recognised by L-Connect 3 or Device Manager
In certain setups, the screen’s USB connection may not be recognised by L-Connect 3 or Device Manager when connected to specific motherboard models. After a thorough investigation, we found that this issue is caused by insufficient power delivery from certain CPU_FAN PWM headers. The HydroShift II LCD-C 360 draws power for the pump, screen, MCU, and RGB directly from the motherboard's PWM header. Due to differences in motherboard design and default BIOS settings, some headers may not provide adequate or stable power.
Solution:
• Enter your motherboard’s BIOS and set the connected fan header (recommended: CPU_FAN, AIO_PUMP, or PUMP) to PWM or DC mode (not AUTO).
• Additionally, set the fan port to Full Speed (100%) in either PWM or DC mode to ensure stable power delivery.
Revision
Starting June 12, 2025, all new LIAN LI HydroShift II LCD-C 360 units will be equipped with an updated PCB featuring a revised resistor to resolve this power-related issue.

Pump Speed Not Adjustable in L-Connect 3
We’ve identified a software bug in L-Connect 3 V2.0.29 that prevents pump speed adjustment for the HydroShift II LCD-C 360 when operating in USB mode (when unbound from L-Wireless Sync setup or not using the wireless dongle).
Solution:
This issue will be fixed in L-Connect 3 V2.0.30. Please wait patiently for the next software update.
