Very Weird System Temps while running the I7 2600k @ 4.3GHz vcore not setting correctly on asus p8z68-v LE

Edit:
I found out that HWMonitor gives false readings on some motherboards. Which explains AUXTIN, CPUTIN, TZ00, TZ01. I'd still like to know why vcore isn't setting properly. And if 71C is too hot for TMPIN3 while running prime95

I don't know what's wrong with my temperatures but clearly something is wrong. I overclocked my Intel Core i7 2600k processor to 4.3GHz because when I bought my PC it had only 3.8GHz stock settings and It has liquid cooling. I seem to get stable temperatures and correct readings for the processor while running prime95 for a couple hours and they are stable. (I make sure it doesn't exceed 75C)

However, TZ00, TZ01, CPUTIN, AUXTIN are all messed up while running prime95. Apparently TZ00 and TZ01 are always @ 82 F and 85 F while CPUTIN is between 84C-91C idle and while running prime95 it goes all the way down to 13C? How is that even possible to be running @ 194F while idle and 54F under full load? Also, AUXTIN seems to stay @ 61-66C idle and while running prime95 this also decreases to 54C

Here are the temperatures after running prime95 for a couple minutes:

Here are the temperatures when my PC is idle:

TMPIN3 seems to be a correct reading. The temp stops at 70-71C which seems pretty hot to me but I'm no expert.

Why is it doing this? Also, why does my motherboard ignore my vcore setting for the voltage and pick its own? Say I put 1.35v for vcore voltage while running prime95 it'll say 1.304v and drop to 1.28v later in the testing stage until the system fails because it ignores my vcore setting

Motherboard: Asus P8Z68-V LE
RAM: 16GB 1600Mhz
Processor: Intel Core i7 2600k 3.4GHz -> 3.8GHz (Stock)

If it is less than 60 days the store might do an exchange on the board.
I would try for a gigabyte model the overclocks are limited but less chance of burning up the board there is always a tradeoff.
Asus does not limit their boards for engineering reasons thus the reason for a LN2 setting on there boards.
Gigabyte limits there mother boards to what a good custom water cooing setup with TEC’s can handle this is not a cheap setup to do but gives you some comparison to the types of limitations that I am speaking of.

After doing some research on the issue that you are having, it seems that a bios update may fix the temp reading issue, but if not a RMA of the board is necessary, there are some that had to return two boards before getting one that would work correctly. Sorry for the bad news, but better to know than to stumble through this. So try the bios update first see if that fixes the problem if not return the motherboard.

Applied update 4101 and the update worked. It turned my computer on an off by itself about 10 times until I finally Booted up windows (extremely fast) until I realized that my processor is now magically overclocked to 6.0GHz my computer shut down so quickly i couldn't even open up hwmonitor to see if it fixed it. I had to click on factory settings like 10 times until I can fix the clock speed to 3.8GHz. I click reset multiple times I ended up having 4.34Ghz. Sometimes the bios settings completely froze now. This -.- idk the mb is shit and the update on their website almost burned $300 on fire
