The Externally Variable Controller (Yellow)

Function:

User can vary the console’s fan speed anywhere

between demand and full speed.

Can be used to set higher-than-standard minimum

speed.

Detail:

Same function as the red/white but these modules can be fitted to your console and allow the speed of the fan to be varied from outside the case. They will not, however, allow the speed to be reduced below that which the system demands. In other words, there will never be too little cooling. The control potentiometer (pot) is designed to be fitted through the console case and secured with the nut (provided) which will require at least one hole to be drilled, although there is no reason why the cable shouldn't be passed through a small slot and the pot attached to the outside of the case using glue or double-sided tape... or even just left hanging! A drilling template will be included with the module. This version of controller is only available for certain consoles as the more recent boxes have too little space inside to fit the required control pot. However, if you are happy to find your own means of mounting the pot in one of the consoles with limited space, I’d be more than willing to create a one-off controller for your needs.
