Lian Li vs ARCTIC AIO Specs
radiator size
The ARCTIC Liquid Freezer II 420 features a massive 420mm radiator. This larger surface area allows for more heat dissipation compared to the Lian Li GALAHAD 240mm AIO. The Lian Li unit uses a standard 240mm radiator with high-density aluminum tubes. While the Lian Li design includes fourteen rows of aluminum tubes to maximize surface area, the ARCTIC unit simply offers more physical space for airflow. A larger radiator generally provides better cooling potential under heavy loads. You get significantly more cooling capacity with the ARCTIC model due to its sheer size advantage in this direct comparison.
socket compatibility
The Lian Li GALAHAD 240mm supports a wide range of modern sockets. It is compatible with Intel LGA 1700, 1200, 115X, 2066, and 2011, as well as AMD AM5 and AM4. The ARCTIC Liquid Freezer II 420 data explicitly lists support for LGA 1700 only. While the ARCTIC unit is designed for Alder Lake processors, the Lian Li cooler offers broader backward and forward compatibility across different generations of CPUs. If you plan to upgrade your motherboard platform frequently, the Lian Li unit covers more bases with its extensive mounting support list.
lighting
The Lian Li GALAHAD 240mm includes customizable RGB lighting with addressable LEDs. The 240mm version features thirty-five addressable RGB LEDs embedded in the block for complex lighting effects. It also includes an LED controller and syncs with mainstream motherboard software. The ARCTIC Liquid Freezer II 420 data does not mention any RGB lighting features. It focuses on functional cooling rather than aesthetic customization. If you want visible lighting effects in your build, the Lian Li unit provides this capability out of the box, whereas the ARCTIC model appears to prioritize performance over illumination.
fan control
The Lian Li GALAHAD 240mm uses 120mm fans with variable speed control. These fans operate between 800 and 1900 RPM in PWM or DC mode. They provide a rated airflow of 69.17 CFM. The ARCTIC Liquid Freezer II 420 features PWM-controlled fans with a speed range of 200 to 1700 RPM. The ARCTIC unit also includes an additional 40mm VRM fan that is PWM controlled. This extra fan helps cool the voltage regulator module. The Lian Li fans have a higher maximum speed, but the ARCTIC unit offers specialized cooling for VRMs which the Lian Li data does not mention.
build quality
The Lian Li GALAHAD 240mm utilizes a triple-chamber pump design. This combines the pump, connecting, and cold plate chambers into one unit to reduce friction and prevent leaks. It also includes a five-year warranty for worry-free liquid cooling. The ARCTIC Liquid Freezer II 420 features a quality control sticker indicating additional testing. It highlights a more efficient cold plate and pump design. The Lian Li unit explicitly details its leak prevention technology and warranty length. The ARCTIC data emphasizes efficiency and quality assurance but does not specify a warranty period or leak-proof chamber design in the provided text.
