Ozcraig-one of the reasons i brought this topic up is because it triggers my alarm when the fan goes off. The fan activates intermittently , so you don't really know when the bloody thing will turn off completely. I need to somehow wire the alarm so its independent of the fan.
Also i have 1 10" fan on 4 core radiator. I'm not sure whether its enough. Well nothings fried yet, so time will tell!
