Errmmmm, proof of what, the core being taken from a diode? Tell me what you want proof about and ill see what proof I can dig up for you!

Well I mean that when looking for temps that you need to be looking at the Core temperature and not the CPU temperature itself. I just remember that someone told me to disregard the Core temperature and just look at the CPU temperature. So if you could find something to back that up (to look at the core and not CPU temperature) I would greatly appreciate it. Not that I don't believe you but what if it actually is the CPU temp. I could overclock it by so much more

This is what chozart said in one of my other threads:

Oh, I understand. Ill find proof in a moment, but let me first explain the logic behind the truth. When Intel or AMD give the thermal specifications for a chip, they need to create a way for the consumer to measure that temp. In order to get a uniform test, the temps must be taken from the same spot. When it comes to motherboards, these temp diodes that measure the "CPU" temp can be placed in different spots. This could effect the temp reading, and as such, give an inaccurate temp reading. As you know each mobo is made differently. Because of this they place diodes in the CPU to read the temps, that way its uniform for every CPU out there, no matter the other hardware. Anyways, ill go find the proof, but thats the logic behind the proof.

its true however this diode is always around 10 degrees hotter than the mobo sensor (because its closer to the core)...which corresponds with the 38 cpu temp and around 50 temps you gave us

So pretty much what you are saying is. This temperatures are right. They are just a lot more accurate than most motherboards are? So should be able to go a little beyond 55C? maybe to 58C without causing any kind of damage?

Ok guys, here is the deal. Check out the pic I am going to post, it shows the correct place to measure the Safe operating temp of the CPU as taken from a guide for my particular processor. AMD might have a different place, though I doubt it. Anyways, the temp readings you get from the thermal diodes within the CPU are placed very near the core (core temp), much closer then the diode you get that will give you the temp for the CPU (which is placed on the motherboard.) Where temps are concerned, you want to use the closes measurement you can get to the the Case Temperature location, which is why you go by core temp, and not CPU temp.

Edit: I just got done reading the thermal spec sheet for the X2 procs, unfortunately, the max temp for these procs is not listed well at all (it says 49-65 as shown in the attached Pic). That being said, you need to understand that all of these specs are for procs at STOCK settings and at stock voltages, which is something you need to take into consideration, the higher the voltage, the more chance of quantum tunneling, and as such, you need to keep the temps lower. (That last comment is an assumption, someone correct me if its wrong.)

I've gotten more heat most of the time from Large FFTs and Gromos Core test...


My "Core" Temp is lower than my CPU temp in SpeedFan....

Everyone I know uses the first Temp1, so I have no clue where or when people started using the Core temp... Just like Chozart said, most everyone goes by the CPU temp, it's normally in the socket I think, so it's pretty consistant on most mobo's...

I go by core simply because in EVEREST and SPEEDFAN it readsd generally 5-8C higher at any given time than my 'CPU' or "TEMP1" readings, and if ANYTHING in my rig besides the GPU goes over 70C Im in a bit of trouble regardless, so I keep a close watch on BOTH to be safe, and for you dual core guys, I think the max temp spec is closer to 60-65C IIRC...

Those are some very interesting observations frogy, in your case I think I would take the higher of the two and consider that one to be your core temp. Anyways, no offense to everyone you know, but they "should" be using their core temps as the temp measurement. In most cases the core temp only fluctuates +/- 3c from the center of the IHS (where the suggested max temps are taken at). The temp diode that is placed on the motherboard can fluctuate anywhere between (-) 8-14c from the top of the IHS (this is from personal experience). It is for these reasons that people *should* be using the core temp when considering what is safe for the CPU. Here is a little research a member did about the accuracy of the Core temp diodes and why they should be used.

I'll go boot my comp really fast and look at my temps, I may, and probably likely am wrong about my Core being lower than the Temp1, but I'm pretty sure from what I remember the Core was lower...

I'll edit this post in a second
