Features: brand new and high quality Made of high-quality material, durable, firm and has a long service life.4PIN PWM intelligent temperature control speed control pin + 5V 3PIN ARGB motherboard synchronization pin.Supports AURA SYNC. The use of 9 high-brightness lamp beads and the transparent frame have less light decay. Hydraulic bearings. Long-term use guarantees greater oil storage, longer life, and at the same for time reduces shaft disturbance, and supports PWM speed regulation with a wider range of precise adjustment. Strengthen the frame structure design. The black shading frame reduces stray light, and the combination of full transparency and matte multi-faceted brings a variety of diffuse light effects. 9 fan blades design. Increasing more air intake and enhancing the air renewal rate in the chassis can make the major hardware work better and more stable. Frosted materials are more diffuse. Vibration damping, low noise, quiet and efficient. Eight large-area rubber shock absorbers are distributed to help smooth operation and reduce vibration and additional wear.
