Reedy Power 40mm Aluminium 8.4v High Voltage Cooling Fan

Lowering a motor's operating temperature improves efficiency and power output while extending its life. Reedy's HV (High Voltage) Aluminium Motor Fans feature a CNC-machined housing for maximum durability. Silicone lead wires provide extra protection against heat. A handy 195mm extension is simple to install by plugging directly into your receiver where it operates off BEC voltage. Because they feature HV compatibility, they can also be soldered directly to ESC battery terminals when using 2S batteries to achieve maximum RPM and cooling. Installing in the vehicle is as easy as double-sided tape or fitting it to your favourite fan mount or heat sink.
