Inaccurate temperature reading in PC Probe II and Everest

I recently purchased a new system based on this motherboard. Everything works fine except one peculiarity. When I enable PC Probe II and Everest at the same time, the temperature reading is erroneous. But when I run single software, the reading is correct. Is this normal?

When you execute two or more hardware monitoring software, such as PC Probe II or Everest, at the same time, the software may read/write from the super I/O chip simultaneously. This simultaneous read/write can induce conflict with the super I/O operations. Consequently, the temperature reading from the super I/O chip is not correct. To work around this issue, it is recommended to run 1 hardware monitoring software at any time.
