Function: Increases the console’s fan speed by 50% of the demand.  Detail: In a standard, unmodified, console the fan will typically spin at  about 20% of full speed when cold. With this module fitted it will actually spin at 30% of full speed.  As it warms up and more cooling is required the console will ask the fan to spin faster; the module will continuously follow this demand, always adding 50%. So, if the console demands (say) 40% spin speed the resulting rate with the module fitted will be 60% of full speed.  In use, because the initial fan speed (and hence the airflow) is greater than normal, the console will take longer to warm to a temperature that requires additional cooling, and when it does it will be cooled more quickly, thereby decreasing the thermal stress on the APU which is a major cause of console failure.
