Aerocool EasyWatch Fan Controller Auto Fan Control? (How Does Auto Function)

[fcastro]

Hi everyone,

I am looking at a fan controller for my system since gigabyte decided to only include 1 fan speed controller on my new motherboard (EP45-UD3P). I have been looking at the Aerocool EasyWatch Fan Controller because its an auto controller of the fans and it has no knobs (my case door has little to no space when it is closed.

Question: Does anyone know how the Aerocool decided at what speed to run the fans at? I know it had a few temperature monitor probes but how does it decide to run a fan at 100% versus 20% without it being given any range of specs?
