Ali's own Hardware Monitor that ships on the CD supplied with the Mobo.
A basic util that does the job, but the shipped one can cause shutdown problems. There is an email address in the readme file. Email them and they'll send you the latest version.
Option 2 is Motherboard Monitor 5 and the Ali module.
It works ok for temps but is a bit off with the voltages.
search google for Motherboard Monitor and you'll find what you need.
What gets me, there is NO link to the additional dll and ini files that are needed for the newer chipsets. And the link where I found it at OC.com is now gone. So I'll stick the zip file on my webspace. Download the beta ALI files here:
The CPU temp seems to work fine for both, but I think there's something wierd going on with the system temp thermistor or MBM - mine is reported at about 33C, when I have a senfu temp probe sitting inside the case right next to the system thermistor that tells me it's 25C.
