The data sheet is here:
http://www.analog.com/UploadedFiles/Data_Sheets/878926113ADM1030_a.pdf
so this chip has two thermal sensors, one internal one external ( measuring CPU temperature I guess ) and it can control one fan, either by temperature or by maintaining a programmable RPM value, defaults to temperature.
Main differences are that the temperature thresholds can only be programmed in 4C steps as 5bit values with 3 bit specifying the range in which to control the fan in 5C increments ( so when reaching Tmin the fan will spin slowly, if the temperature raises it will go faster and reach full speed at Tmin+Trange ). And the fan speed reading is only 8 bit vs. 16 bit on the 7467 but that's hardly a limitation :)

have fun
