Novak’s Cooling Fan with Guard: 40x40x10mm provides additional airflow to R/C electronics for improved performance. This is the same fan that is included in the Novak Activ8 Racing ESC (#1725), and can be used with any other ESC, motor, or electronics that accepts a 40x40mm fan. To provide additional protection, an “X”-shaped, durable, plastic guard is included with four, socket-head cap screws. The cooling fan features a factory-installed, two-pin JST plug that easily plugs into the Novak Activ8 or any ESC that includes fan output fins that accept a two-pin JST connector. Operates from 5 to 7.2 volts.
