Antec mod - in power We trust convex dual lighting Ring: convex designed dual lighting Ring offered best RGB lighting Effect. The slope of the Tangent line for the calculated Convex design is at 2. 76, which prove to yield the best lighting result. In simple words, Convex design kept RGB lighting Effect at a optimal point and left tolerance for other RGB components such as, Mobo/RAM, water cooling components, and SSD. 16. 8 million colors & 18 independent controlled LEDs: 18 separately controlled RGB LEDs painted you rig with16. 8 million colors. With dual ring, total 18 separately Controlled RGB LEDs smoothed out the overall RGB effect and leaves no gaps between LEDs. synchronizable RGB lighting via motherboard: sync ready with all Mobo houses including gigabytes, ASUS, MSI, and as rock. extreme cooling performance - 45. 03 CFM & 2. 56 mm: max fan speed up to 2000Rpm; Air pressure Max at 2. 56 mm; airflow Max at 45. 03 CFM. Pwn fan optimized heat dissipation and hydraulic bearing ensured Ultra quiet operation. : 2 years; do not connect non-addressable RGB fans into our addressable control hub. support: Please email us at support@antecmod for any assistance.
