Asus P5B-VM SE (LGA 775) motherboard with an Intel Core2 Quad Q6700. The motherboard and CPU tempature readings are reversed. The Asus utility shows them correctly however. Have not had time to install previous versions to check for the issue.
I have an Asus P6TD Deluxe motherboard that shows them correctly in the latest version Speccy as well as all versions going back for two years.
Have an Asus P5G41T-M LX PLUS (also LGA 775) motherboard waiting for a new build so we will see if the same issues show up on that one.
I didn't see the same issue in the forums unless it is an older posting.
