A method and combination apparatus for cooling air circulated by a fan. A first step involves providing a fan having blades and a drive motor which rotates the blades. A protective cage encapsulates the blades, thereby preventing persons or objects from accidentally contacting the blades when they are rotating. A second step involves securing to the protective cage one or more packages of frozen matter. Air circulated by the blades of the fan is cooled as said air passes by the frozen matter.
