hi I recently (after much frustration) downloaded the Smartguardian program from the ITE site, as the Asus Q-Fan control is crap. I found this prog to be quite versatile (although i still cant control fan2 & 3) I then found out that DFI actually have this prg listed in their support section, so i downloaded that version to compare. It would appear they r different versions, the ITE site version is 111kb, the DFI version is 5.7mb! Included extras in the DFI version are a prog called smart-speed-NF4, which i couldnt get to work stably on my asus NF4 I couldnt get a version number from the ITE file, but it has more options for fan control even though tis a smaller file. Does anyone know which version is newer? and does the smartspeed prog work ok on DFI boards?
