Intel® Core™2 - Max Temps?

[Big.Wayne]

Hi,

what is the general thinking on how hot these processors can run? I had a look on the INTEL website but any documentation I can find is written in gooble-dee-gook that I can't understand.

I am testing a CPU at the moment but it appears to be running very hot under 'full' Orthos load . . .

Have anyone got any linkage to somewhere that explains the upper limits of these chips please, also I'm after a tool that shows if the CPU is throttling?

I'm not sure if this reading above is correct or if I have made a hash of installing my heatsink but the machine is running fine, although I am aware that at some point it should begin throttling and beyond that the machine may close down, but at what temp does this happen?

thanks in advance

Tat will show throttling - frequencies will go down.

Thanks, I was also keeping an eye on CPU-z watching for it to lower the multi but nothing so far?

The 1mb chips have a tjunction of 100c , same as Quads !!
Not the 85c of the C2D Conroe/Allendales.

Thats right, sadly I have no idea what tjunction means? I'm not sure that has anything to do with the max specified operating limit specified by INTEL?

Does nobody know anything about this subject then?

Hasn't INTEL got any information on this written in layspeak?

Cmon guys its a perfectly straight forward set of questions? one of you brain boxes knows I'm sure?

• What is the safe 'max' temperature the Core 2 Duo is specified to run at?

• At what temperature is the chip 'programmed' to throttle?

• What temperature does the system shut down to avoid damage?

Just having a look through the datasheets

Damn do you have a degree in thermal engineering then? it made no sense to me whatsoever

QX6800, max , max working 54.8 (measured center top of CPU), storage 85C (ie processor not running).

E6xxx/E4xxx, max working 61.4, and presumably storage 85C

Max Working is 61.4°C, what does that mean? also I don't understand what 'storage' means in relation to this?

I've heard the figure 82C for throttling but I've never seen anything to back it up.

Yes I have 'heard' a lot of stuff over the years too, its like a web chinese whispers, someone say this, someone else says that?

But what is the truth?

I can look up the specifications on any hard-drive and clearly read in plain english what the safe 'operating' temperature is . . . if I go below or above this limit I would expect to have problems, but when it comes to the processor it all becomes a bit 'mysterious'.

Thanks for your time in cracking this Jokester

Storage temperature is basically the temperature you shouldn't exceed with the processor not in use to ensure that it doesn't get damaged or degrade.

Huh? that makes no sense?

So INTEL are saying that its not a good idea to put your CPU into an oven when not in use?

Max working temperature is slightly different as Intel specify it as the temperature on the surface of the IHS in the middle. There's no practical way to measure this. The internal diodes will read higher than this, but how much higher is a bit harder to quantify

Indeed it is?

Did you read this thread before?

The solder that glues on the IHS is supposed to melt somewhere between 85 and 100C as well.

Are you thinking what I'm thinking?

Thanks fornowagain & Jokester,

I appreciate you taking this time to explain this, hopefully some other people will have learnt a bit more on the subject also.
