Thanks for a brilliant program. Yours can read my Gigabyte MB GA-A320M-S2H sensor fine (IT-8686E apparently), whereas SpeedFan (now long out of date) cannot. I have managed to write my own mickey-mouse C program to read and control my old MB chip (Winbond W83627) but cannot find matching 'programming' info for the ITE chip. Do you know where I might find that, please?
