Hi Al, > Intel SHG2 motherboard which I believe uses a Sahalee BMC. It also > employs an ADM1021 which I think does the fan control. (...) Not a chance, as the ADM1021 is a two-temperature chip. It doesn't deal with fans at all. The SHG2 manual mentions an ADM1026 instead, which is a full-featured hardware monitoring chip, and has some fan speed control capabilities. -- Jean Delvare
