The LPC47M182 only supports 2 fans, so I'm pretty certain it isn't actually used for hardware monitoring on your machine. > I tried to take a photograph of the motherboard.

The ICH8 datasheet mentions 4 fan tachometer inputs, 3 fan control outputs (PWM), and two new busses to connect thermal sensors (SST and PECI). The bad news is that we don't support any of these bleeding edge technologies at the moment. -- Jean Delvare
