Hello, Here is mine research: DHG chip is wired as follows: in0 is Vcore in1 is 12V in2 not used in3 is 3.3V in4 is 5V temp1 is MB temp fans are fan2 is cpu, fan5 is not, fan4 is not There is some unknown i2c chip at 0x38 which measures voltages, and fans It measures: Cpu voltage, DDR voltage, SB 1.1V voltage SB 1.5V, CPU PLL voltage, NB 1.1V Dram VTT volrage, VTT CPU voltage, And also fans: Chasis fan1 Chasis fan2 Power Fan And some Opt fans, I know what registers are there (mostly up 0xa0 for fans) So we need to find out what chip it is, because it measures a lot too. The NB temperature etc etc is measured by some chip at 0x40 it seems it also controls some fan temperature??? Definitely what is the output of i2cdetect 0 i2cdump 0 0x40 i2cdump 0 0x38 Thanks, Rudolf
