MBM5 is all fine and dandy (nice stuff you can do with Epox boards) but if you just want ease of use (and a systray temp readout) grab
CPU Cool.
Once you've got it installed just ignore the entire mobo maunfacturer/model thing. Just hit "I don't know" and it'll bring you to the main window. From there just go into the display options and check off which temps you want to show next to the clock when you minimize.
