PWM air cooling solution featuring best in-class cooling performance with patent-pending heat pipe technology. AeroFlow Frame features curved guide vanes built into the frame of the cooling fan to direct and channel air flow better. Comes with built-in RGB lighting effects and compatibility with Addressable RGB motherboards or hubs. Powered by Heat Core Touch Technology (HCTT) with 4 ultra-efficient thermal heat pipes.

PATENT-PENDING HEAT PIPE TECHNOLOGY: Rime 4 heat pipes are designed with patent-pending composite wick material which vastly accelerates the evaporation-condensation phase. This speeds up heat transfer to produce significantly greater cooling performance.

BEST IN-CLASS COOLING PERFORMANCE: Rime 4 outperforms similar price point CPU coolers as shown by thorough cooling performance tests. When compared to other models of CPU coolers, Rime 4 comes out on top with lower Delta temperatures. Delta temperature or ΔT is the difference between measured temperature and ambient temperature which when lower, indicates higher performance.

AEROFLOW FRAME: Curved guide vanes built into the frame of the cooling fan direct and channel air flow more effectively, allowing for maximum cooling efficiency.

ADDRESSABLE RGB COMPATIBLE: Access 16.8 million colors using compatible Addressable RGB motherboards including ASUS Aura Sync and MSI Mystic Light Sync as well as Gigabyte RGB Fusion motherboards using 3-Pin XWD connector.

EQUIPPED WITH 12CM ARGB FAN: Comes equipped with 12cm Addressable RGB fan that can be controlled using Addressable RGB motherboard or LED control button. Translucent fan blades allow you to fully appreciate this fan’s beautiful RGB lighting.

PWM HIGH-PRESSURE FAN: 120mm high-pressure fan provides a stronger airflow to push heat away from the aluminum fins faster. Control your fan speed with ease up to a maximum of 1800 RPM.

HEAT CORE TOUCH TECHNOLOGY (HCTT): Four ultra-efficient thermal heat pipes provide a perfectly flat and smooth surface to maximize contact surface area. This allows for minimal heat transfer loss while in direct contact with the CPU to increase the efficiency of heat dissipation.

HIGH-TECH CERAMIC COMPOSITE COATING: High-tech ceramic composite coating for maximum heat dissipation. Black ceramic coating on fins increases the cooler’s thermal conductivity and heat dissipation capabilities.

HIGH EFFICIENCY FINS: Upgraded high efficiency aluminum fins for maximum thermal performance.
