What does "Temp1" refer to?

In SpeedFan and CPUID Hardware monitor it shows GPU, CPU and temp1 and temp2.

What are the Temp1 and Temp2's?

Are they motherboard temps, air temps, HDD or what?

My system is currently on Prime95 on a high OC (3.5Ghz) on an AMD Athlon thats pretty high.

CPU - 47
GPU - 43
Temp1 52C
Temp2 - 36.

I have 6 case fans and a corsair h-50 cpu cooler, 9600 gso GPU.

Any ideas?

 

Well I always thought it referred to Cores, but I thought I'd check before answering and apparently....... I was wrong lol

This might help although the link is broken in the thread but someone pasted the relevent section.

I've read that, thankyou, but i'm still unsure.

If it helps - When folding or running prime 95 the Temp 1 shoots up instantly to 52-53 whereas Temp 2 stays around 35-37.

 

Temp1 is likely to be the temperature of your northbridge chip, and I would imagine temp2 is the southbridge.

 

Ah, thankyou.

Is there anyway i can find out for sure?
