Abstract
Methods, apparatus, systems and articles of manufacture to implement cooling fans with selectively activated vibration modes are disclosed. An example cooling fan assembly includes a motor and a fan coupled to a shaft of the motor. The motor is to rotate the shaft in a first direction to cause the fan to move air. The motor is to rotate the shaft in a second direction to cause vibration from an eccentric mass coupled to the shaft.
