The Adjustable Fan Accelerator (Green, Brown)

Function:

Increases the speed of the fan by a proportion as set

by the user, from 10% to 100% in 10% steps

Detail:

This module does the same as the basic version with the added facility of being able to change the amount of increase by setting the switch to the required position. Each position represents a 10% increase: Posn.1 Fan speed increased by 10% of that set by the console Posn.2 Fan speed increased by 20% of that set by the console : : Posn.0 Fan speed increased by 100% of that set by the console (Speed doubled) Adjustment is made using a small flat-bladed screwdriver to turn the switch to the desired setting. In a standard, unmodified, console the fan will typically spin at  about 20% of full speed when cold. With this module fitted and (say) set at “4” (40%) it will actually spin at 28% 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 40%. So, if the console demands (say) 40% spin speed the resulting rate with the module fitted will be 56% 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.
