Max temp on Intel paper for Core 2 Duo is ~60 degrees C

[Kantana]

The question is whether that is measured by the digital thermal diodes on each core as measured by Core Temp or whether that is the temp as measured by the motherboard. I have an Asus P5W DH motherboard and loaded temps for a E6600 at 3.6G is:

Core temp: 51/68 degrees C idle/load
Speedfan: 36/53 degrees C idle/load

The difference in temps measured by Core Temp and Speedfan is 15 degrees C, that's a huge difference. If Intel measures the temp by the core thermal diodes then I'm way over the limit! :eek:

What do others think on the max operating temps of the Core 2 Duos? Before the Core 2 Duos we had to rely on the thermal probs on the motherboards for cpu temps, is Intel changing their way of measuring max temps now or are the core temps reported wrong?

if you used the stock heatsink, speeds, and voltages then itd be pretty easy to find out whether core temp is the one its talking about

core temp is actually the best value, as these are right in(?) the die.

at least for me it is this way : mobo-cpu-temp is lazy. when i start prime for example, core temp reports really fast higher temps, but the mobo realises that few seconds after.

also core temp ist mostly 1-2°C higher.

anyway, where did you read 60°C ? i thought it is 85.

In other words, thats just what Intel recommends for stable ops.

So what is the thermal throttling temp for Core 2 Duos and measured from which, core temps or the motherboard temps? The heat sink doesn't feel like it's 68 degrees C, it doesn't burn to the touch whereas on the P4 before it would feel hot.

The throttle is from the core temp. And if the HSF is only warm could mean its not making good contact, not that the cpu's cool. I get low 50's core temps with prime at 3.6GHz/1.55v on tuniq on mid speed.

there is many debates about temp measurements on Conroes...

I cant seem to work it out either ... 68C on load ??? man, the heatsink would be HOT to touch... yet it isnt is it ?

I have Celery D at 4Ghz and its 51C under load, when my conroe and celeron machine are next to each other, and I try to touch the heatsinks, the celerond one burns my fingers, where Conroe is just plainly nicely warm, nothing hot at all ... I know its simple measuring but logically, I can not understand why these temps are so high and at the same time I do not believe that the new intel HSF is so efficient, that it releases all this heat without heating up much ...

if you don't know your temps, use this tool. it's confirmed by gigabyte staff to be absolutely reliable and has nothing to care with mobo, cause it's a diode inside the core, so should work with any mobo :

If i trust that, both of my cores are at 15 degrees.

Excellent.

ROFL :p:

Unless you are living in an iglo :D

ehm look at the second link, page 20.

it tells that the maximum CASE temperatur for a 65W cpu of 6000series (so the conroe is) has to be less then ~62°C.

CASE TEMPERATURES. so in all cases i know, the case is cooler then the cpu. so if the case is allowed to have more then 60°C by intel himself, the cpu must have less then 60°C ? how realistic is that ?

also page 39. just as what i observed. the fan should start full power at above 66°C. very good if the temp should be lower then 60°C ? same on page 113


that all makes no sense. they tell that CPUs are reliable until 60°C, but advice the hsf-companys to make their fans start fullspeed at 66°C ?

that's like driving a 1/4 mile with medium speed and after finish line you go full power :rolleyes:

so one of both is wrong and i really believe it's the 60,1°C number, cause it starts throtteling at 85°C. so if anything above 60°C would be critical, they wouldn't wait with throtteling until 85°C.

anyway, i never reach such values even with possibly crappy mounted boxed cooler...

i can only tell what was told to me from reliable source. if it don't works for you, i'm sorry. everyone else i know had no problem with that tool.

At stock the Core temps are 11 degrees C higher than motherboards, there's a huge difference and it rises as the Vcore goes up. On 1.5375 Vcore the difference is 15 degrees C.

As for thermal throttling at 85 degrees C on core temps, Prime fails before then at higher than 73-74 degrees C. Oh well, no need to worry about throttling I guess if my pc will crash before then :p:

It now seems to work for me as temps are about the same as in Everest ( 1° different) 66°/67° I'm running Prime for 14h ..

With my former E6400 ES that tool was not working so it depends
