✅ The 80mm fan operates at a constant speed of 1600 ± 10%. This allows for significant increase in efficiency. ✅ The PC Fan airflow is up to 33 m³ / h and the noise generated by the blue LED fan propeller is 13,9 dB, which makes it a very quiet and efficient fan in its class available on the market. ✅ Highly efficient operation and 80x80x25 mm dimensions allow the fan to be mounted on the heatsink for efficient cooling of the processor instead of the loud noise of other fans from different Cooling Fan manufacturers. ✅ The Quiet Fan mounting is very simple - the fan is mounted on 4 screws, attached just like the standard, allows quick and easy replacement of the loud fan. ✅ The modern FDB (Fluid Dynamic Bearing) with oil fill ensures quiet operation and extended lifespan up to 100,000 h.
