The core temperatures have an equational offset to determine temperature which equalizes at about 45 Celsius thus giving you more accurate readings at peak temperatures. The hindrance in this is the sub ambient idle temperature readings you speak of.

The silicon and adhesives used in manufacturing these processors has a peak temperature rating of 97+ Celsius before any form of degradation will take place. The processor also has a thermal shut off safe guard in place that shuts the processor down at 90 Celsius.

The Cpu temperature is read form a sensor embedded within the socket of your motherboard causing about a 7-10 Celsius variance form the actual Cpu temperature, which may be what you are reading about on the net.

You can use an application called AMD overdrive, that will allow you to monitor your temperatures accurately.

As long as your core temperature has not exceeded the high side of the 60 degree mark for extended periods of time you should be ok. 62 degrees holds a generous safety net to begin with.

I hope I was able to answer your questions, If you have any more inquiries don't hesitate to contact us.

Like I said, core temps are not an accurete way to read temps. For example, I had two (2) 960T's this year. Both of them would identify "Core temp" in AMD Overdrive, AIDA64 as well as other programs as being very low. As a quad at 4.3ghz with around 1.5v, core temps were in the mid 20's under load. CPU Temp was in the mid 50's under load. Under no load, core temps were in the single digits....

Anyone who knows anything knows that you cannot get load temps below ambient unless your using extreme cooling.

Core temp is pretty much worthless. Look at the "CPU" temp instead.
lol

Yeah, because a calculated value is more accurate than an actual sensor....

What should I be using to monitor temps for 9x5 cpus?
post #24 of 28
AIDA64.

(and just so everyone knows, AMD hosts the datasheets on the socket design and thermal sensors on their website. Have fun.)

That's because AMD uses a certain algorythm to calculate the Core temps. There's a bunch of popular threads talking about this. The Core temps are best used to read load temps, CPU for idle.

Take a look at this thread HERE I did a mini experiment to see how CPU Temps and Core temps rose per core.

This was done in the summer months, and it was a very hot one for sure. Ambients were usually around 25-26C range. Looking at that pic using 3 cores (since its the most stressfull of the three tests doen) I had a CPU Load temp of 36C - on water cooling mind you. Core temps were 26C on all cores, even tho only three cores were loaded @ 100%... go figure. Ambient temps were aroudn 25-26 so how could the core temps be this low?

I could have easily used a +10 offset to bring it up ot the CPU Temp, but who's to say if that's even accuarate.

Your IBT obviously didn't push that 95W chip hard enough biggrin.gif

Core temp is a misnomer. It's not an actual temperature, it's based on the threshold for maximum cooling required. Core temp doesn't equal real temp until 45'C. It's quite a useful reading for those that know how to interpret it. If you don't, I wouldn't suggest overclocking on air or water.
