Abstract: Provided is a neck fan for personal cooling which can be supported by a lanyard around a wearer's neck so that a cooling breeze may be directed to cool the wearer's face and neck area while the wearer's hands are free to be engaged in ordinary activities of work, leisure, play, —, —, etcetera. The geometry of the construction of the fan device is such that it lay close to the body of the wearer so as to minimize the fan device from coming into undesirable contact with other items in the wearer's environment. The lanyard which supports the fan device about the wearer's neck may be provisioned with an optional break-away safety link so that should the fan device become accidentally entangled with the environment, the breakaway safety link will permit the lanyard to separate before the wearer will be seriously injured. The lanyard system also provided length and angle adjustments.
