So far I'm impress with the Koolance board and software, I receive it today and make a quick install with only the pump tach attach to it, with the setting show on hte pic it shutdown my PC in around 3-5 secondes, it use a bypass wire connected to the power button connector of the motherboard, you simply conect the button wire on the other end of the by pass. I order a flow meter and a coolant probe, when I'm gonna receive it, I'm gone install also the 5 temp sensors include with the kit .
