Product Features
Single-Tower Cooling with 4 Heat Pipes: Built around a 4 heat pipe single tower design, this cooler is made to move heat away from the CPU efficiently. AGHP technology and the symmetrical all-aluminum fin stack work together to expand the heat dissipation area. That means you can push your system harder while keeping temperatures under better control. Daily use feels more stable when the cooler can keep up with sustained loads.



Quiet 120mm PWM Fan Performance: Cooling is handled by a 120mm TL-P12-S PWM fan designed to balance airflow and noise. With fan speed up to 2000RPM+10%, it can ramp up when you need extra cooling and slow down when you do not. Operating noise is rated at <= 29.8db (A), helping keep your PC comfortable to sit next to. The 4PIN PWM interface makes it easy to integrate fan control through your system.
Digital Screen Top Cover Monitoring: A digital screen top cover adds a practical way to keep an eye on system behavior while your PC is running. Using TRCC software, it can display CPU temperature, CPU usage, graphics card temperature, and graphics card occupancy. This makes it easier to spot rising temps during gaming or heavy work without constantly opening monitoring apps. The top cover design also improves the overall appearance of the build.
ARGB Sync Lighting Experience: Addressable RGB lighting is designed to synchronize through the 5V 3pin motherboard header for coordinated effects. Soft, colorful lighting adds personality to your system while the cooler continues doing its main job of heat dissipation. This helps you match the cooler to the rest of your ARGB components for a unified look. Performance and color come together without changing how you use the cooler day to day.
Wide Compatibility and Practical Fit: With a 151mm overall height, the heatsink is designed to fit most cases without sacrificing heat dissipation performance. Compatibility covers dual platforms including Intel 14/15th Gen and AMD RYZEN 7000 sockets. Installation accessories are included and can be installed according to the installation video or manual. For AMD platform installation, the original motherboard backplate is required.
