sure don't look right even yopr min is stuck at 3.5 ??? at idle it should drop way down to a low power state [look at mine at min and current when at idle and not under any load]
I guess you could try to clear cmos and with that reset the motherboards bios bact to default to see if a setting got changed by mistake
with that cpu used you also need to be sure your bios is 3.6 or newer
- Support Haswell-Refresh series Processors.
Note
You must use one of the following methods to update this BIOS.

I do know if you flash you need to follow the footnote instructions for using a refresh chip asus is the same and guys run in to issue as well
cause it almost sounds like you may not have the correct bios flashed for use of haswell refresh cpu's ?????
