Same here.
Here's an article from the author of Core temp: http://www.overclockers.com/articles1378/
Looks like both CT and IDU use data off DTS on each die. I don't know what accounts for the difference in readings, though.

Since core temp conflicts with IDU I ended up just using the latter; besides I feel more comfortable since it's an Intel program with a defined temp threshold.
