Temperature monitoring question

[mohdzarif]

I'm so used to HWMonitor. It has two different CPU temperature readings, the one listed above the fans section (which is 70C) and the one below which shows each of the 6 cores readings (which are 54C).

I'm currently running Prime95 Small FFTs.

I always read the top reading (the 70C reading) and ignore the bottom reading (the 54C reading). My question is which temperature should I really look for.

I mean, let's say that it's "official" that the max safe temperature for my FX 6100 CPU is 70C. So which one of the readings should be below 70C? The above one or the one below?

Today I tried using Core Temp and it only gives me the 2nd reading of HWMonitor (The 54C reading not the 70C reading). That's when I started wondering if I look at the wrong reading all this time to keep my temperature safe.

I would look at the 70 degree ones to be more realistic.
My friend who owns an fx 4300, his temps are always wrong and different programs show different results. The 70 degree one seems to be the most correct though for 4.3ghz.

The one is package temp, the others are core temp. You really don't want either of them to exceed the recommended temp but I'd pay more attention to core temp. What kind of cooler are you running? How long was prime running when you snapped the screenshot?

I look at Core Temp and Corsair Link and both of them shows the 2nd reading which is 54C. As you can see on my screenshot of Core Temp, it doesn't report the 70C reading. Corsair Link is the same.

I used Corsair H80i. Prime was running past 10 minutes I think.

I'd run it again, with HWinfo or Core temp open the whole time so you can see the entire range of min and max temp readings for the whole run and if the package temp never goes over 70 and the core temp is staying at 54, I'd say you're good. If you're able to manually adjust the fan speed settings for the radiator to a custom setting where the RPM's go full max at a little lower threshold than they do now, that might not be a terrible idea, but 54c core temp after 10 minutes of Prime isn't too bad at all. It's not long enough to determine stability but it's long enough to gauge temps in most cases.

My H80i was set to operate at "Balanced mode" at the time of testing. I can adjust those things don't worry. And stability is not the concern for this thread. Only temperature.

According to CPU-World, the "Maximum operating temperature" for my CPU is 70C. Which of the two temperatures is it referring to?

Also, I looked at other softwares to monitor the temperature too, Core Temp and Corsair Link, both of them only show me the core temperature (54C) and don't show the 70C reading, which makes me wonder. Is the package temperature something to not be wary about? Why other softwares don't show the package temp, if it's important?

Also, for Core Temp, I read in this in their forum >> http://www.alcpu.com/forums/viewtopic.php?t=892
It says that "Tjunction Max (TjMax) is the maximum temperature the manufacturer has rated their processor at. This value represents the maximum temperature the hottest part of the processor core should not exceed."

As you can see on my screenshot, Tj. Max is 90C. I guess this Tj. Max is the max temp for the core temperature because the software Core Temp only list core temperature, isn't it?

Is the package temperature something not to be really wary at? I don't get it why Core Temp and Corsair Link don't show it.

You know, everybody seems to have a different opinion on this, and AMD isn't very helpful with vague definitions and specs plus a history of faulty sensors. I've always used both HWinfo and Core temp when overclocking and the Core0 in HWinfo or the core temp has always corresponded with the CPU readings in the Core Temp utility, so I go with that.

As I said though, you probably don't want either one going over 75. At 80-85 it will probably start throttling if not sooner and at 85-90 will probably shut down. If you run Core Temp and change the value to show distance to TJmax rather than actual temperatures, you might like that better as it shows you how far you actually have to go before you're at max safe temp. Of course, as with anything, it's not exact, it's a software estimation.

+1 on that, the AMD sensors are just a pain to deal with.
