There must be some kind of sensor, but how does it tell the PSU to turn on the fan? Some kind of EEPROM?
 
I find the RPM it jumps to when it hits 45C is simply too loud, and I'd like to either increase the limit or lower RPM. Would it be possible with conventional means?

    There is nothing you can do to alter the fan speed without voiding the power supply's warranty. If you want to take things in your own hands and void the warranty, feel free to open it in a safe manner and modify it in a way which is safe and makes sense.

    Typically, in this application, the fan is controlled by a thermistor and simple electrical components with no advanced programming, logic, or eeprom.
