A LM78 by any chance? > The manual says that it is a Winbond W83781D Hardare monitoring IC to monitor the system temperature (cpu & system), voltages (core & i/o), and fan speed (chasis & cpu). I don't think too many of us will buy the specialized chasis/cpu fan so it won't detect the rpm for the fan. And I don't know what other ICs are currently being used. It is just an interesting little statistic especially if there are many systems in a room or many hard drives in a computer (i.e. many hot scsi drives). Would be nice to be able to determine from a remote machine what the temperatures are... sort of like a PC health monitor of sorts. > I've had a look at the specs for this device and it shouldn't be too hard > to write a driver for it.
