Though numbers are normal I had never seen something alike= =2E.. Two cores per socket, and 8 sockets on the board? If so, that looks absolutely fine to me. The average temperature is 36.8C but 43.0C is still well within spec. That difference of just over 6 degrees is not really significant and probably entirely due to different airflow patterns over the different CPU sockets. If you swap the CPU package in that socket with one of the other ones, you'll find the hot spot stays put. You might be able to even things out by rerouteing cables, but really it's not worth the hassle and won't make any perceptible difference to performance.
