Advanced Thermal and Acoustic Performance
A whisper-quiet 135mm fluid-dynamic bearing fan keeps temperatures in check without creating excessive noise. The fan’s intelligent speed control adjusts to system load, maintaining near-silent operation during light tasks while providing robust cooling under heavy workloads. This thermal design, combined with the PSU’s 94% efficiency rating, helps maintain optimal operating temperatures for all connected components.
Clean Cable Management for Better Airflow
The fully modular cabling system allows you to use only the cables you need, reducing clutter and improving case airflow. With cable lengths ranging from 61cm to 700mm for various connections, you can achieve a clean, professional build regardless of your case size. This modular approach not only enhances aesthetics but also contributes to better thermal performance by minimizing obstructions to airflow.
