Arctic Liquid Freezer II 280 Multi-Compatible All-in-One Liquid CPU Cooler The Arctic Liquid Freezer II 280 Multi-Compatible Liquid CPU Cooler delivers outstanding cooling performance, keeping your processor running smoothly even under heavy workloads. Featuring PWM-controlled fans with speeds from 200 to 1700 RPM, this cooler ensures efficient cooling while maintaining quiet operation. Thanks to its 0 RPM mode, the fans stop entirely at PWM levels below 5%, offering silent performance during idle times. Additionally, a dedicated VRM fan operating between 1000 and 3000 RPM provides targeted cooling to your motherboard’s voltage regulation modules, improving system stability and component longevity. The PWM-controlled pump, running at 800 to 2000 RPM, ensures smooth coolant circulation, keeping your system performing at its best. Built with a copper cold plate and micro-skived fins, the Liquid Freezer II 280 delivers excellent thermal conductivity, effectively drawing heat away from your CPU for maximum cooling efficiency. Whether you're overclocking or handling resource-intensive applications, this cooler provides dependable, high-performance thermal management. Optimized for AMD Ryzen AMD’s high-end AM4 and upcoming AM5 CPUs use a multi-die configuration, where the thermal hotspot is not centered. Arctic addresses this with a custom offset mounting kit, allowing the cold plate to align directly with the CPU’s hotspot. This design ensures optimal heat dissipation for current and next-gen AMD processors. Best CPU Water Cooler The Liquid Freezer II 280 has been consistently praised by independent reviewers for its performance, affordability, and silent operation. It has exceeded expectations in multiple categories and was honored with the European Hardware Award 2022 for Best CPU Water Cooler. Outstanding Performance Capable of handling thermal loads over 200W, this all-in-one cooling system is compatible with the most powerful CPUs from both Intel and AMD. It excels in heat dissipation, even during intense overclocking, and outperforms many competitors in both cooling efficiency and noise reduction.
