Maximum safe temperature?

The maximum safe temperature for a 2700K is 72C what does this mean though? Does this mean any of its 4 physical cores can only handle 72C or does this mean the entire CPU can handle 72C? http://ark.intel.com/products/61275/Intel-Core-i7-2700K-Processor-8M-Cache-up-to-3_90-GHz

Here is info as me no smart.

 

Doesn't answer my question at all, but thanks for the insight. Also according to Intel the maximum safe temperature for a 4770K is 72C not 105C as this video stated. I'm pretty sure by 100C the system would've already shutdown to prevent CPU damage. I'm looking for maximum safe temperature not maximum temperature where it'll force a system kill.

I want to say "Maximum Safe Temperature" is how hot the CPU can be for sustained operations and still remain reliable until the end of the warranty period. Processor degradation (which heat accelerates) causes reliability errors over time, which is probably more important for people who run servers and other mission critical system.

I have a blog! And a list of guides I've posted

Are these temps under load?

I'm afraid to swear now because the overlords might hurt me.

72c is the tcase value which is the rated safe temp for the IHS. The cores themselves are safe up to 105c although most people tend to stay below 80-90c at load for everyday usage.

Got it looks like I can try 5GHz for this then.

Yea overclocked 4.5GHz. Using AIDA64 CPU/FPU/CACHE Stress.

The TCase specification is used for mass system builders. The 72C degree number is useless information for the individual end user. This temperature can only be correctly measured by mounting a thermo thingy at the center of your CPU.

 

Unfortunately Intel does not trust software like ADIA 64.

 

Your temps are HELLA good. 

 

Feel free to correct if wrong.

Your question cannot be answered due to it implying there is a specific safe temperature. You know how processors are made? Binning and stuff? There are all sorts of variances between individual units and tolerance to heat is among them. What's good for one unit, might kill another. The 72 degrees, you mentioned is the stock tcase temp for 4770K. But as everything else, it varies. If the BIOS determines, the CPU can handle more, it'll allow it. If you turn off speedstep, all bets are off and so on. Also tcase is measured at the heatsink above the cores, which'll always be cooler than the cores themselves.

 

If you want to know more about a safe temperature for your particular CPU, set everything to stock, give it some stress and hinder it's ability to cool down. Unplug the fan for example or hold it with a finger. At some temperature your CPU is going to thermal throttle. That's when it's just exceeded it's safe temperature. Be quick to cool it back down before it crashes.

Those temps under load are fantastic.

In theory you can keep pushing your cpu as long as you keep temps down and supply enough power provided your bios lets you. BUT this WILL shorten the life of the cpu and if you push it to far you do risk killing the poor thing.   

 

But I will only overclock to what I find I will practically need. 4.5 is where I shall stay. 

 

(Still no expert but just a random guy who thinks he is smart)

The fact that you overclocked your CPU to 4.5GHz and still get under 60C under load, is VERY good. I don't understand why you're worried? You're fine man :P 

I'm not worried I just wanted clarification and insight from the community. I got this CPU used for quite cheap but was never overclocked and can confirm that as I know the owner personally is not deep into tech, so I snatched it off them.

72C is at the heatspreader, not the die.
