The dc cooling fan listed here carries 5V, 12V, 24V, 0.7W, 1.1W, 1.65W, 2.52W, 3.00W, documented exactly as the manufacturer publishes it. Quantity and destination market determine the final price — tell us both for a firm quote.
Static pressure is the number that matters when a DC cooling fan has to push air through a filter, a heatsink or a packed enclosure, and this 75mm unit reaches 10.46mmAq at its top speed — several times what a general-purpose fan of the same size manages. Five speed grades from 3500 to 7000RPM let noise and airflow be balanced at design time. Available in 5V, 12V and 24V with flow control.
