Air cooler AEROCOOL Rime 4 120 mm hydraulic bearing fan, 4 heat pipes, TDP 230 W, black

The Aerocool Rime 4 is a 120 mm air cooler designed to provide efficient CPU cooling with a hydraulic-bearing 120 mm ARGB fan and a maximum airflow of 75.3 CFM. It uses four heat pipes with Heat Core Touch Technology (HCTT) and a high-efficiency aluminum fin stack with black ceramic composite coating to improve thermal conductivity and dissipation. The cooler supports a wide range of sockets including LGA 2066/2011/1700/1200/115x and AM4 and is compatible with addressable RGB control via 3-pin ARGB headers.

Advantages

Patent-pending heat pipe technology with a composite wick accelerates the evaporation–condensation cycle to improve heat transfer. The AeroFlow Frame integrates curved guide vanes in the fan frame to better channel airflow for increased cooling efficiency. The 120 mm PWM high-pressure fan offers up to 1,800 RPM for stronger airflow, while the translucent blades and built-in addressable RGB lighting provide 16.8 million color options when connected to compatible ARGB motherboards or controllers. Heat Core Touch Technology ensures a flat contact surface between heat pipes and the CPU to reduce thermal transfer loss.

Suitable for

• Desktop PC builds requiring efficient air cooling for mainstream and high-performance CPUs
• Systems where ARGB lighting synchronization (ASUS Aura, MSI Mystic Light, Gigabyte RGB Fusion) is desired
• Compact or mid-tower cases where a 155 mm cooler height fits

How to use

Install the cooler following the motherboard and cooler mounting instructions: attach the mounting brackets to the motherboard socket compatible with your CPU, place the cooler so the flat heat-pipe base makes full contact with the CPU heatspreader, and secure the cooler with the provided screws. Connect the 3-pin ARGB cable to a compatible addressable RGB header for lighting control and plug the PWM fan cable into the CPU_FAN or SYS_FAN header to allow automatic speed control. Verify clearance inside your case to ensure the 155 mm height and 120 mm fan fit without obstructing RAM or other components.

Recommendations

For optimal performance, apply a thin, even layer of thermal paste between the CPU and the cooler base, ensure the ARGB and PWM headers are connected properly, and maintain unobstructed airflow inside the case by managing cables and using case fans as intake and exhaust. Regularly clean dust from fins and fan blades to preserve cooling efficiency.
