We use brushless motors, the faster they rotate, the greater the airflow produced, which enhance cooling effect. However, this also leads to increased noise. How often is the dust-proof cotton typically replaced? It usually needs to be replaced every 3 to 6 months. the dust-proof cotton can prevent dust from entering the laptop, thereby extending the lifespan of the laptop Why can the V12 series only reach a maximum speed of 2800rpm? Through repeated testing by our engineers and found that a 5.5in large-diameter fan only generates noise close to the maximum acceptable level at a maximum speed of 2800 RPM and achieving optimal cooling efficiency What are the differences between V12 and V13? V13 simply lacks RGB lighting; all other functions and heat dissipation capabilities remain the same with V12.
