coretemp just been debunked?

Intel uses the same diodes that Coretemp uses for determining when to thermal throttle.

There's no doubt that a industrial temperature probe will give you the most accurate measurement of temperature where you stick the probe, just you can't stick a probe directly inside the core itself and neither will the average user have a probe or the skills/tools to mount it inside the IHS.

The reason Intel and AMD measure the temperature on the IHS surface is that is what coolers are required to cool.
 
i just use 2 temp monitors, coretemp and intel TAT theres maybe a few degrees between them @load, but in normal day to day use i dont worry about temps, my rig has passed 14 hrs+ in orthos temps of 58'c @3.6ghz in normal use, even gaming it will never be stressed that much.
 
Maybe the diode is calibrated so that it shuts down before there'd be damage ie at 90 and not the rated 100 for example?

I am happier that it reads the temps higher rather than lower tbh. very interesting to see the big difference between them.
 
As Jokester says, looks to me like Coretemp is showing the internal core temperature, as 11C higher than that on the IHS sounds very plausible.
 
Well, the heat spreader has a certain amount of thermal resistance (albeit as low as they can get it), so it's not going to be the same temperature as the core. Besides, it's the core we're worried about, not the piece of metal that goes over it.
 
Also its worth noting that the temp prob was located right between the two cores. In the case of a quad I would have thought it would be best to use a dual probe setup, one probe directly above each core, like so.....

The closer the probe is to the die the more accurate its reading is going to be.

Thats the way I would have done it anyway :)
 
question is, when does the core shut down occur? when the core temperature reaches 100c? or when the heat spreadder temperature reaches 100c?

id say its always best to go with the temperature given by the on die thermal diode. but not sure how things work with them when it comes to accuracy/calibration.

also hardocp method can;t really work with laptop cpus that don;t have the IHS, so its got to be the on die diode temps that have to be used.

Depend which cpu you have, Tjunction max values vary

You could do it, but you would have to machine out a groove in every cooler to situate the temp probe, I don’t think it would be as repeatable as having it on the ihs permanently, but it would be pretty much in the same location.
