That is the thing about speed fan. You can't just install it and expect the labels to be correct. That app is only telling you what it sees. You have to figure out what it sees, and I'm not stating that at the OP but anyone who doesn't understand that.
The temps listed are a typical list of just a fresh install. Basically:
Temp 1 and 2 are going to be the Tcase & Chipset temp. You would need perhaps the MB utility app to figure that one out.
Temp 3 is not really tied to anything, Speed Fan just senses something but what would be -2? :lol:
Core0 and Core1 are the Tjunction temps or DTS sensors on the CPU cores themselves.
The core would be the GPU.
The ambient is the ambient temp of the video card. For Nvidia cards, when you click on configure button on Speed Fan, you will also see that info in the chip column.
Also can't remember if the 4.33 will have the correct max tjun temp to base the core temps correctly. That is one reason why I use core temp, in that situation.
