Which temp is my real CPU temp?

[SickBeast]

I'm using Open Hardware Monitor. It lists several CPU temperatures. I'm wondering which one to use.

Here is a screenshot:



It says that my "CPU Package" is at 73C, but at the top it says that my "CPU" is at 62.5C. Which one is more accurate?

CPU is a sensor on the motherboard near or underneath the socket, so it's not all that accurate. CPU Package seems to be the highest Core reading(both at 73c) and will be more accurate.

Ok thanks.

Is 73C a good temp under full load for a 2500k at 4.6ghz using 1.4v?

Over 72c isn't good at all. http://ark.intel.com/products/52210

Intel lists the maximum "Tcase" for the i5 to be 72.6c. And even at these temps I wouldn't consider it perfect for 24/7 use. Strange, you should be able to milk more out of it at that voltage. Maybe I just got luckier, but I'm running 4.7GHz @ 1.35V. Are you using the stock heatsink/fan?

EDIT: Bad reading on my part, you said it was under FULL LOAD. I guess that while running 100% those temps are great for 1.4V. Just make sure that while playing games or doing multitasking it doesn't go over 70c.

Don't know anything about that processor, but that sure seems hot to me.

You're fine, there is no sensor for Tcase.

 

[Hatisherrif]

Still, it could be running cooler. Try the best stable overclock at 1.35V.

He's about 25C away from throttling, I wouldn't be concerned over it.

SB use RealTemp and Prime95 it for about 10 minutes.

Well I backed down the voltage a bit and I'm at 67C under full load now at 4.6ghz.

Try another temp app. , Your temps are wherr it says core 1 and so on. its ok if one core is 73 another at 63. The CPU is not flat, its concave!

your temps shouldn't go over 65c. gl

I still don't think thats so bad. I only got to 4.1GHz @ 1.27v and my LinX temps are 71-73C at full load. This is after pulling the 212+ off, re-TIM'ing it, adding another fan, etc.

When gaming, my temps only get into the low 50's, and that's what really counts.

I've tried some of the other temp programs, I like RealTemp the best.

I find it worrying how much misinformation there is about CPU temps. Simply because people dont understand the basic concept of the different numbers. And uses information provided for OEMs at for example ark.intel.com.

Lets first be clear, your CPU is fine until it throttles. 90C for example on a desktop CPU is no problem. Nor is 95C in a laptop CPU. Nor will it lower the lifetime in any worrying way. The biggest danger to CPUs is overvoltage.

Now back to the temperatures.

This is how Tcase is measured:

And a few other of the temperatures can be seen here:

So can we please stop the blatant misinformation about temperatures by mixing Tjunction and Tcase?
