If it makes you feel better my cores are 33c, 40c, 37c and 21c at idle. I can't figure out why one core is so far less than the others nor why some are so high for idle either. All i can guess is that's a side effect of them using paste on the processor instead of the solder, less consistency perhaps? I too have reseated the cpu block thinking i botched the paste job but afterwards all cores were the same idle temps as they were before. If someone has an idea how to fix that i'm totally game for 4 cores in the high teens/low 20's 
. And the 20C difference is still there after getting the cpu loaded up for 20 minutes. Highest core is mid 60's and the one is low 40's.
