Yet another CPU temp question

post #1 of 14
Thread Starter 
I am getting mixed answers on this and am confused. What temp is the correct temp to read on my 1090t the core temps or the cpu temp? according to this from an amd rep said the below, and if what he says is correct is there still the 10c variance. Do I need too add 10c to the core temp if that is the right temp to read or cpu temp? or is it the core temp right. I thought I had it understood but too many conflicting answers out there.

Sorry I didn't get back to you sooner, I just recently had your email forwarded to my department.

Concerning your question regarding the temperatures with your processor. (1090) the maximum temperature threshold is 62 Celsius which set for the internal die (core) temperature of the chip. 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.


Thank You

Am I really reading this right? the CPU Tempature is the problem, and not the cores?

So I can happily watch my cores hit the high 50's, whilst my CPU tempature is hovering 68-75 maybe 80C?

Hmmm, if this is true........ then I better rethink my overclock, plenty of protential left to OC XD, Core's idleing at 11C and load is 26C

I read this before today, someone else's post or was it you in a diff. thread ? It was always believed that the Thuban sensors were only accurate after 45c, but this confirms it as a fact.

Strange enough my cpu socket temp is in line with my core temps, mostly due to having a big case and the backside of the mobo has some space that air might be circulating.

For people having high cpu socket temps, if the motherboard tray has a CPU hole, you can put a 95mm fan there to help temps. CPU may be ok but the socket components might have a temp limit.

so it is the core temps? that are the actual cpu temp? and the cpu temp is really the socket temp?

Yeah, but what AMD said is follow the Core Tempatures, and not the CPU Tempature I believe.

Right now, Iv'e got different cores fluctuateing between 16-17C at Idle atm

just got off the phone with a amd tech guy and he said that the variance is not an error in the cpu its an error with the program reading the signal and go by the bios temp. How the heck can I monitor the temp in bios when running benchmarks

lol! BIOS monitoring whilst benching XD, would be class!.....

Anyways.... AMD gave us the answer saying that.... we should read the core tempatures, especially from AMD Overdrive...... ...... ...... CPU Tempature must be the socket it self, and the core tempatures are the acuall cores, so cores and socket are seperate.

Will give Overdrive a go now and compare it to HWMonitor, this Core tempature thing is too good to be true though.... I could go flying upto 4.5GHz right now and don't care what voltages I use

what gets me is everyone who ever said cpu is the one to watch wrong? if this is so why has no one else heard this? or has the temp bein wrong thing just ignorance. I somehow doubt that. somthing is awry. once bulldozer comes out I will be moving my 1090t over to my msi790fx gd 70 to see just how far that thing can go before it blows up haha then i will know what temp to watch out for hahaha j/k

I go by core temps only. Monitored by either HWMonitor, or Core Temp. I glance at the "CPU" temp to make sure it isn't anything crazy like 100c, but it never goes over about 64ish while my core temps never go over 49ish while in prime.

Watch core temps. Make sure they don't go over 62c. Try and keep it below 60. Then you will be golden.
