Coretemp seems to be off quite a bit

I remounted the heatsink (side note: curse you, Intel - was that meant  
to be funny?), and didn't apply a single bit of paste other than what  
came on it.  I don't have the ability to boot Windows on this system,  
or at least not without some pain (it's a server with no extra drive  
space I could readily set aside to install it, for starters).

Since fiddling with the heatsink, the temperature was down to 45C at  
boot.  I did another "make -j4 buildworld" and it got up to 58C.   
Since killing that build, it's slowly working its way back into the  
high 40s (currently bouncing between 48 and 49).
