well it looks ok to me. voltage wise.
quite frankly without mucking around in your actual bios and trialling various settings i cant think of anything else to do. the board as it is set is dynamically adjusting voltage as it alters frequencies up and down on the cpu which is ideally what you want it to do. by manually setting core voltage and core frequncy (by not using auto) this would give you more control. in my opinion. are you saying you cant change from auto to manual in the "advanced""cpu configuration" menu in the bios?
cpu load line calibration might help - set it to manual and try out the different llc options. sometimes this will actually raise the cpu voltage for added stability, but you wont know until you try the different settings. perhaps try disabling llc. this might lower the voltage aswell. but personally ive always selected the load line calibration manually. ie enabled and set to a specific level.... trial and error (and trial and success
) whatever gives stability at the lowest voltage.
disable load line calibration this will lower your cpu voltages give it a go.
hyper 212 evo cpu sink is a good price to performance. many people swear by it.
