127 degrees C typically means that no thermal sensor is connected to
that input. So you can ignore this input.

76 degrees C is admittedly very high, but then again it depends what it
is measuring. Don't trust the default labels which may or may not apply
to your motherboard. You should compare with what the BIOS says. Also
look at the motherboard documentation, in my experience Intel board
have a good description of where the thermal sensors are located.

If the temp1 value never changes, you may try changing the sensor type
and see if you get better values. But the BIOS should have set the
proper type for you already.

According to coretemp your CPU isn't too hot, so you really don't have
to worry for the CPU.
