Core temp vs cpu temp

I set up a sensor reporting energy on my Ubuntu machine (a desktop computer machine) and also it reports drastically various temperatures for the ACPI CPU analysis and the ISA Core 0/Core 1 reading.

You watching: Core temp vs cpu temp

The ACPI states the CPU temperature is 31.5 C, yet the ISA adapter reports the Core 0 is 55.0 C and Core 1 is 56.0 C.

Why carry out the "CPU" and "Core" temperatures differ? Are these sensors in different areas on the motherboard?

AMD Temp Indevelopment and Guide

We"ve had a couple of excellent threads freshly where members contacted AMD and asked what temps they should be looking at, what the max temp was on, and what programs have to be offered and why. But this indevelopment is still scattered and also not well defined in one location. It additionally doesn"t quite define when you have to be looking at certain temps. Well I"ve made it my mission to incertain that world are reading the appropriate temps and have been trying my ideal to give all the indevelopment each time I respond without sounding like a broken document. So I determined to compose this information threview and little overview to aid you out tbelow.

What is "Core Temp" ?

"Core Temp" is what AMD refers to as "TCTL" and also is a non-physical temperature on an arbitrary scale measured in degrees. It does not represent an actual physical temperature favor die or situation temperature.

What is "CPU Temp" ?

"CPU Temp" is check out by a sensor in the socket of the motherboard. It is a physical temperature and therefore will be effected by ambient temps inside the situation.

Why have to I use "Core Temp" and when?

AMD designed this equation to accurately review peak (45C+) and load temps. It has actually an equational balance out to recognize said temps which equalizes at 45C. Due to the fact that it"s designed for top temps and also is a non-physical temperature it cannot check out idle temps or account for ambient temps properly.

So what is "CPU Temp" good for then?

At peak temps this value is frequently 7-10C better (depending on motherboard) than the actual temp because of it being a physical sensor. At idle it"s a small even more precise, yet still not dead on, and besides idle temps carry out not matter near as much as load temps carry out.

AMD says my chip has actually a Celsius limit, what value is this referring to? This limit appears type of low, why?

This is referring to "Core Temp" of course.

So for example Phenom IIs have actually a recommended 62C "Core Temp" limit while not exceeding 60C for extended periods.

It has long been suggested that the recommended limit is merely a bigger safety and security net. Tright here is a thermal shutdvery own in the chip at 90C and the silicone is rated for 97C+, so it appears plausable that we might indeed go better, yet this guide (and the majority of in general) will certainly ssuggest nod and also point you to the recommfinished limit for your chip.

What programs review "Core Temp" ?

AMD recommends the Core Temp routine and AMD Overdrive therefore.

The core section of HWMonitor additionally reads this worth, but be careful as it likewise reflects CPU Temp.
