systin 40c tmpin3 54c and tmpin6 45c
hwmonitor says tmpin5 is 127c though that's worrying although another thread stated this is an error but I did swap thermal paste recently.
And if any part of the cpu hit 127c it would obviously shut down right?

You'll have to check the manual, but tmpin sounds like an external temperature input that is not currently plugged in. These will sometimes show a max temp of 127C if not plugged in.

I was considering msi cpuz, but I read a reddit thread claiming cpuz can install adware, hwmonitor I thought was pretty reliable, but im not sure what to do now if I cant trust the software I use to monitor temps. I don't want to shut off and go to the bios just to check my temps every time.

You will see it's in the mobo section in hwmonitor. These sensors are not standardized and are read incorrectly on many mobos when using 3rd party software. It will only be read correctly by the mobo software. I doubt it's an external temp sensor unplugged. It shouldn't read a random number plus most consumer mobos don't have it.

I read that the max temp for that particular sensor is 127c so when unplugged it displays the max number not some random number.

it's an encoding question. Basically there are different methodologies to store/encode data in binary. A "signed bytes" use 1 bit of a byte to decide if the value is + or -, the "sign". Meaning there are 7 bits to store the data each bit can be one of 2 options 1 or 0. So 2^7 is 128, or 0-127. If the byte is unsigned then you'd have a max value of 255, but you could run into a situation where the temperature drops below 0 and results in a value of 255 degrees instead of the correct -1. My data encoding knowledge is a little rusty but there are some other options like floating point (16 and 32bit) 2's compliment.
