What is cpu package, cpu ia and gt core temp?

[tigersty1e]

I'm new to SB/IB.

What are these temps measuring?

CPU Package
CPU IA cores
CPU GT cores

And I see watt readings for the below 2 readings. What power is it reading?

CPU Package power
IA cores power

IA=Sensor placed in the cores, GT=Sensor placed in the GPU(On the CPU) and Package=Temp of the CPU package itself.

I have my internal graphics turned off in the bios. Any reason why those values are shown?

And the cpu package temp is equal the IA cores and about the same as my hottest core temp. It's below my cpu temp.

I should be going off the cpu package temp or cpu temp when overclocking and watching out for high temps?

use core temps as they are most accurate and located in hot spots.

cpu package power is power dissipation in watts of cpu. cores is what used by cores.

turning graphics off doesnt turn its sensor off.

And package is actually same as core 0 (Atleast on IB).
