1. A system comprising:an enclosure including two compartments wherein a first compartment is accessed via a door including a locking mechanism and wherein a second compartment is secured via a cover;
a game control unit, disposed within the first compartment of the enclosure, including a frame, two heat dissipation units coupled to the frame, a plurality of electrical circuit boards forming a game controller, coupled to an outside of the heat dissipation units adjacent to walls of the enclosure,
wherein the game controller includes a CPU, GPU, RAM, BIOS and a mass storage device storing game software and wherein the game controller executes the game software to control a wager-based game played on an electronic gaming machine;
a first fan disposed within the second compartment; and
a first plurality of apertures, between the first compartment and the second compartment, which allow air driven by the first fan, to move between the first compartment and the second compartment to cause heat from the heat dissipation units to be removed from the first compartment;
wherein the heat dissipation units in the first compartment are disposed adjacent to a first side of the first plurality of apertures such, such that when the door to the first compartment is locked via the locking mechanism and the cover and the first fan is removed from the second compartment for servicing the first fan, the game controller is not exposed to tampering allowing the first fan to be serviced by a service technician without a presence of security personnel.
