iMac core (not heatsink) temps

[Hookflash]

I recently purchased an i3 iMac, and I'm starting to get a bit worried about the temps. Temperature Monitor is reporting a CPU temp of 60-65 C under heavy load (e.g., while transcoding with Handbrake), which is fine; however, after enabling TM's "extended x86 driver" (Monitor -> Install driver for extended x86 support...), I'm seeing actual core temps (i.e., not the CPU heatsink temp that you see by default) of 80-85 C.

Is this normal for core temps?

They're referring to CPU heatsink temps, which aren't really a concern for me. I'm worried about core temps (i.e., the actual internal temp of the CPU cores).
