CM Hyper 212 evo on an FX8350? And a question regarding temps

post #1 of 15
Thread Starter 
I haven't done this in over a year or two so I just need some backup to what I did. A couple hours ago I received my 8350.

After over clocking it to 4.5ghz and doing a stress test, my cpu temp was climbing and climbing and it got to 80c in core temp. I dont think this is right lol. Maybe too much thermal paste?

And while it was in idle stock, it was idling at 7c... Thats 44f. My room temp is appx 60f... I'm using core temp 1.0r6.

No idea, faulty temp sensor??

4.5 GHz on the 8350 with that cooler is really pushing it. The Hyper 212 evo is a great budget air cooler, but I don't think it can handle and/or dissipate the heat that these FX chips put out too well when overclocked. What is your vcore set to?

Vcore was at stock.

I didn't run prime95 because of the temp but I played a solid 2 hours of crysis 3 and the core temp, at least according to core temp, never pushed past 45c. I suspect the temp reading is off though..

Never mind guys. I just did a bit of research smile.gif

Your temperatures and temp sensors are fine. You motherboard has a built in sensor that measures the temps at the CPU socket. Your CPU ALSO has a built in temperature sensor , but due to the formula used to calculate this temp, it is only accurate under load. Your CORE temps are the ones that you need to look at and monitor under load when stress testing. I think the general consensus for Vishera is that your core temps should not exceed 60 degrees celcius.

But this information is still scattered and not well defined in one place. It also doesn't quite explain when you should be looking at certain temps. Well I've made it my mission to insure that people are reading the right temps and have been trying my best to give all the information each time I respond without sounding like a broken record. So I decided to write this information thread and little guide to help you out there.

What is "Core Temp" ?

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

What is "CPU Temp" ?

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

Why should I use "Core Temp" and when?

AMD designed this equation to accurately read peak (45C+) and load temps. It has an equational offset to determine said temps which equalizes at 45C. Since it's designed for peak temps and is a non-physical temperature it cannot read idle temps or account for ambient temps correctly.

So what is "CPU Temp" good for then?

At peak temps this value is typically 7-10C higher (depending on motherboard) than the actual temp due to it being a physical sensor. At idle it's a little more accurate, but still not dead on, and besides idle temps do not matter near as much as load temps do.

AMD says my chip has a [INSERT SPEC] Celsius limit, what value is this referring to? This limit seems kind of low, why?

This is referring to "Core Temp" of course.

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

It has long been argued that the recommended limit is merely a larger safety net. There is a thermal shutdown in the chip at 90C and the silicone is rated for 97C+, so it seems plausable that we could indeed go higher, but this guide (and most in general) will simply *nod* and point you to the recommended limit for your chip.

What programs read "Core Temp" ?

AMD recommends the Core Temp program and AMD Overdrive for this reason.

The core section of HWMonitor also reads this value, but be careful as it also shows CPU Temp.

Where are you getting this information?

Aside from the great information threads below, I am a Mechanical & Computer Design Engineer who has several colleagues that either currently work in AMD's engineering department or used to.

Ok there are two things you need to keep an eye on when it comes to temperatures. If you use HW Monitor or any similar program like HW64 you should see that there are two temperatures. There should be something labeled package and then there is CPU temperature. The MAIN temperature you want to worry about is "Package" temp. This is the temperature of the physical CPU die on the processor. The maximum continuous for that is 61C although short spikes upwards into 70C won't do any harm. As it says Package temp is only accurate under load. It can not account for idle temps properly. An example is in South Africa it is summer and temps get up to 35C. But my Package idles at 10C??? CPU temp is the temperature of the CPU socket. And the Maximum for this is 72C continuous as far as I remember. Once again a short spike above that won't cause harm and most AMD boards throttle the system when it reaches 80c.

Cooling an overclocked 8 core FX is going to be hard for a 212. It is a great cooler but I do not think that you be going above 4.5GHz on it.

Very informative posts above. I know they were meant for wardoc22, but it will help me out as well once I start overclocking my 8320. Thanks for clearing all that core temp/cpu temp stuff up guys.

You CANT measure the stability with gaming.run prime95
post #8 of 15
Your temps sound about fine for that cooler. With my 8350 and Evo 212 4.5GHz its about 62-64C on Prime95. You could probably get a few degrees off by checking airflow, cable management and thermal paste application. The cooler is really good value but sadly cannot keep up very well with the temperatures of a AMD FX when you start clocking frown.gif It's recommended to keep the temperature around 62C.

Alright guys, thanks for the advice, I reverted back to stock clocks. How well would the h110 cool the 8350 at around 4.7-5ghz? I have 2 gtx 770 in SLI and a sub HD monitor and.. them CPU bottlenecks at 4ghz..

What was your Vcore during Prime95?

If you have LLC set too aggressively, it will bump the Vcore too high and you will have crazy temps.
