What Temps Are What? (In Speedfan)

I just got my watercooling installed and I downloaded Speedfan to find out the temperatures of my processor and my gpu. But all I see is Temp1, Temp2, Temp3, etc. How do I figure out what temp is what?

go into your BIOS and check the order of the temps listed and make sure the numbers relativly match what speedfan says. they're usually labeled in the BIOS so you can figure out what matches what.
