Mac Pro dual CPU: Temperature difference between CPUs

[Parigot]

I have a Mac Pro 2009 (4.1) with a dual 2.26Ghz Quad-Core.
I realized that there is a ~10c difference between CPU A and CPU B.
I cleaned it up when I bought it a month ago. Removed a lot of dust, install new fans...but still.
Has anyone seen this or experienced it before?

I'm joining a screenshot of the iStat temperatures.

Thanks
