northbridge temps on GA-EG31M-S2 mobo

hello everyone,

i'm wondering what tmpin0 and tmpin2 are on my motherboard, as soon as i overclocked my Q66600 to 3Ghz, my tmpin2 temperature jumped from ~35 degrees C to about 44 degrees C.

What are these temperatures??

sorry about the lack of info.

CPU- Q6600
Motherboard- GA-EG31M-S2
Memory- 2x2gb cas 4 timing 2.0v OCZ 800mhz ram

in HW monitor it shows the following, what are the 2 temperatures in red?
