are you running the version 4.40? it is the newest version and it shows it has been updated for Z97 boards and yours is on the list.
edit: I looked at the top of the pic you posted and see that you are running version 4.40
so I would just say it's a issue with the software.
I never trust software to read temps or voltage on my system, I use a volt meter and for temps I have a inferred heat gun.http://www.guru3d.com/files-details/hwinfo64-download.html
