✅ The 40mm fan operates at a constant speed of 1900 / 3200 ± 10%. This allows for significant increase in efficiency. ✅ The airflow is up to 4,25 / 7,35 m³ / h and the noise generated by the propeller is 20,9 dB, which makes it a very quiet and efficient fan in its class available on the market. ✅ Highly efficient computer fan operation and 40x40x20 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 manufacturers. ✅ The mounting of this mini fan is very simple - the 4mc fan is mounted on 4 screws, attached just like the standard, allows quick and easy replacement of the loud 40 mm fan. ✅ The modern FDB (Fluid Dynamic Bearing) with oil fill ensures quiet operation and extended 3D printer fan lifespan up to 100,000 h.
