1. Forward/Reverse Rotation: Choose between forward (blowing air towards the back of the fan) and reverse (blowing air towards the front of the fan) rotation modes. The combination of these two options allows for a better display of the fan's hub, removing obstructions from fan brackets and creating a visually stunning and cool lighting effect. 2. Infinite Lens with Raindrop Illumination: The PC case fan features multi-sided high-definition lenses that create an infinite loop effect, resembling a gateway to a mysterious dimension. The raindrop design on the side adds a sleek and futuristic touch, perfect for creating a high-tech and visually appealing atmosphere. 3. Vivid and Detailed Color Effects: With external and hub illumination, this cooling fan supports for COOLMOON's 6-pin music controller for true color ARGB effects. It utilizes 16+10 high-density and high-brightness ARGB LEDs, capable of displaying 16.8 million colors, resulting in vibrant and saturated lighting without any light leakage. 4. ARGB Sync + PWM Intelligent Temperature Control: Connect to compatible motherboards with 5V ARGB headers from for compatible with ASUS, MSI, Gigabyte, ASRock, etc. If the motherboard doesn't support 5V 3-pin ARGB headers, an additional ARGB controller is required for software control. Moreover, ARGB CPU cooler supports intelligent PWM temperature control, adjusting fan speed automatically based on CPU temperature, providing energy efficiency and quiet operation for your enjoyment. 5. High Airflow Design for Efficient Cooling: The fan blades of ARGB pc case cooling fan are designed with a combination of biomimicry and aerodynamics, featuring seven large airflow dynamic fan blades. Even at full speed, the fan operates smoothly, generating strong airflow and a maximum airflow volume of 39.5 CFM for effective cooling performance."
