✅ The fan operates at a constant speed of 600 ± 10% at 12V. This allows for significant increase in efficiency. ✅ The 140mm fan airflow is up to 100 m³ / h and the noise generated by the propeller is 8,6 dB, which makes it a very efficient and quiet fan in its class available on the market. ✅ Highly efficient operation and 120x120x25 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. White fan blades make it also more appealing than standard black ones. ✅ The mounting is very simple - the 140mm case fan is mounted on 4 screws, attached just like the standard, allows quick and easy replacement of the loud computer fan. ✅ The modern FDB (Fluid Dynamic Bearing) with oil fill ensures quiet operation and extended air cooler lifespan up to 100,000 h.
