Ready Out-of-the-Box Installation
The ARCTIC Liquid Freezer III 420 A-RGB All-in-One CPU Water Cooler is designed for immediate use with minimal setup required. It comes pre-installed with radiator fans in a push configuration, ensuring optimal airflow right from the start. The fan cables are integrated into the hoses’ jacket, allowing for a single connection to the motherboard. This streamlined setup simplifies installation and reduces cable clutter. Additionally, the included MX-6 thermal compound ensures effective thermal transfer between the CPU and cooler, further simplifying the installation process.
Future-Proof Compatibility
This water cooler boasts impressive compatibility with both Intel and AMD sockets, including the upcoming LGA1851 socket. ARCTIC guarantees that the Liquid Freezer III will be compatible with future Intel processors without requiring a new cooler. This forward-thinking design ensures that your investment in the Liquid Freezer III will provide reliable performance even as new CPUs are released, making it a future-proof choice for both current and next-generation builds.
Silent and Efficient VRM Cooling
The Liquid Freezer III features an advanced VRM fan designed to provide effective cooling for the voltage regulators on the motherboard. The 60 mm PWM-controlled fan operates quietly while ensuring adequate airflow, especially in scenarios where tower coolers might fall short. This enhanced VRM cooling is crucial for maintaining system stability and extending the lifespan of voltage converters, particularly under high loads or overclocking conditions.
Innovative Contact Frame Design
The cooler includes a patent-pending mounting frame that addresses the issue of CPU deformation caused by Intel’s Independent Loading Mechanism (ILM). By minimizing mechanical stress on the CPU and motherboard, this design helps maintain consistent cooling performance and prevents long-term damage. The frame allows for easy installation and ensures that the cooler mounts securely to the CPU’s backplate, reducing stress and enhancing overall system reliability.
Optimized Water Pump Performance
ARCTIC has refined the Liquid Freezer III’s water pump for both performance and noise reduction. The PWM-controlled pump is designed with an extended fin surface and optimized water pipes, improving cooling efficiency while maintaining quiet operation. This optimization ensures that the cooler delivers excellent thermal performance without generating excessive noise, making it suitable for both gaming and professional environments.
Versatile Control Options
The Liquid Freezer III offers two distinct control modes for flexibility in cooling management. Users can opt for separate regulation, allowing independent control of the pump, VRM fan, and radiator fans via a splitter cable. Alternatively, an all-in-one control mode enables management of the entire unit through a single connection, simplifying adjustments and monitoring. This versatility allows users to tailor cooling performance to their specific needs and preferences.
Enhanced Radiator Design
The radiator of the Liquid Freezer III has been redesigned to enhance cooling efficiency. The 38 mm thick radiator now features a 23% larger cooling surface area due to an increased fin stack. This expansion not only improves heat dissipation but also increases the liquid volume within the cooling system. As a result, the cooler can manage heat buildup more effectively, providing sustained cooling performance during extended periods of high usage.
