High-Performance Cooling: Our nine-blade fan reaches a max speed of 1800RPM and attaches directly to the motherboard via the 4pin interface providing optimal cooling for your case. PWM Control:The PWM function enables the motherboard to precisely control the fan speed as needed. This ensures adequate cooling while minimizing noise levels. 5V ARGB SYNC: Advanced ARGB lighting system with 5V 3PIN ARGB motherboard synchronization support. Switch between multiple RGB modes to add color to your computer case.Caution: Do not connect to a 4pin 12V RGB_HEADER. This will damage the LED strip. Low Noise: Equipped with eight soft anti-vibration pads, our fan operates at a maximum noise level of only 18dBA, ensuring a quiet environment while in use. Hydraulic Bearing Design: Our high-quality bearings ensure stable fan rotation, minimal noise output, and an extended lifespan of up to 40,000 hours per fan.
