▋Product Description

Lori Best 4U Active Air Cooling CPU Cooler for AMD Ryzen Processor AM5 Socket

The air cooling cpu cooler is designed for AMD Ryzen 9 Processor like AMD Ryzen 9 9950X or other processors, AMD AM5 socket. The AMD AM5 cpu cooler is aluminum fins soldered on the copper base with 5 heat pipes for 4U server cooling solution, Support 180Watts CPU Power Heat Dissipation. If swithcing to a 6000 rpm fan，TDP can be up to195W. The 4U server active cpu cooler has been fully tested and validated by Lori to ensure the best quality and cooling performance.

▋Key Features

01
High-Efficiency Cooling with 5 Heat Pipes
Equipped with five high-performance heat pipes that rapidly transfer heat away from the CPU. Combined with a copper base and aluminum fins, this design maximizes thermal dissipation for stable operation under intense workloads.
02
Powerful PWM Fan with Wide Speed Range
Features a 4-pin PWM fan capable of speeds between 1900-3800 RPM. This allows for dynamic cooling—quiet during everyday tasks and powerfully active when you need it most.
03
Dual Ball Bearing Fan
Built with a dual ball bearing structure that offers longer lifespan, better stability, and consistent performance compared to standard sleeve bearings—perfect for 24/7 operation.

04
Optimized Airflow & Low Noise
Delivers up to 61.46 CFM of airflow while keeping noise levels as low as 44 dBA at maximum speed. Enjoy a balance of strong cooling performance and a quieter computing environment...
05
Perfect Fit for AM5 Sockets & 4U Chassis
Specifically designed for AMD AM5 platforms with a compact footprint. Its 4U height compatibility makes it an excellent choice for space-constrained cases.
06
Supports High TDP up to 180W
Handles thermal design power up to 180W, making it suitable for overclocked Ryzen 9 CPUs and extended gaming or rendering sessions.
