i'm looking to whack 2 120mm 240v beast's on my heatercore, but i want to be able to controll them with my hardcano rheobus.

i have had a proffesional electrician tell me it cant be done. i dont belive him. i reckon it might be possible with some kind of relay, so that the voltage accross the 12v line is directly proportional to the voltage accross the 240v line (12v=240v, 10v=200v, 6v=120v ect.) i have no clue how to do this :shrug:

any ideas guys? come on, i know your all genius's... or genii?
