Overheating is the most common Xbox 360 problem. If you are
playing non-stop, there may be a tendency that your Xbox 360 will
crash or freeze due to overheating. If you are the type of gamer
who spends most of your time playing than sleeping, you may want to
consider the location of your console.
Make sure that it is in a well-ventilated environment and do not
put them on cabinets, as there is poor ventilation if they are in
an enclosed area may cause to overheat quickly. You may also want
to consider purchasing a cooling unit to avoid overheating during
long sessions of gaming.
