I think core temp.... is officially buggered.

[Yoxxy]

It seems as if It depends on what motherboard you have for the basis if CoreTemp is accurate. I wish the author would either: post the source code, tell us where in the white pages he got TCaseMax of 85, or tell us why just changing motherboards would change what Core Temp reports. Until then it appears as if the program is full of bugs.

[geforce man]

ive done more testing, Loaded for 2 hours, @ 1.344 volts (loaded volts, NOT EVEN FAR FROM STOCK VOLTAGE) im getting 85c according to coretemp. Think thats right? i highly doubt it. i dont care if were talking about hottest part of a cpu or not, it would be throttling by then. my system is in my sig, DS3, 3400Mhz 425x8 1.406 in bios, 1.39 in windows, and 1.344 loaded. again, only slightly higher than "stock" volts, now, you tell me, if the heatsink is heating up quite a bit, (nowhere near my a64 x2 @ 2800Mhz tho) and your telling me, that coretemp is correct @ 85c? i doubt it. im guessing maybe high 60's, but even then i dont know, because this is extremely close to stock v's.

I concur. I do not believe CoreTemp is reading correct, atleast on my P5W DH\Allendale combo.

[One_Hertz]

what if the digital thermometer core temp reads from is whack? Why does everyone think that its not giving bs readings...

[dissident]

I'm on water and coretemp reports the same temperture or 1-2 degrees less then what the asus utility/bios reports. Running P5B Deluxe.

Before I lapped my IHS coretemp would report significantly higher temperatures then the motherboard... 10 degrees or so.

[rodman]

So what the hell are we supposed to use to measure cpu temps then

[nikhsub1]

Use the Intel Thermal Analysis Tool then... I have uploaded it for easy download HERE

[hypnotoad24]

Suppose I'm getting 50-55C somewhere under load and I touch the heatsink, shouldn't it at least be a bit warmer (because it leans more towards COLD)...? I want to call BS on core temps.

[nikhsub1]

Everyone stop crying about coretemp... just download Intel's thermal tool. Go cry then.

[G H Z]

No! Intel's tool lies also!!!!

I think many differences are explained with IHS/Core & IHS/HS contact.

[geforce man]

well, i dont know, or at this point really care which is more accurate, all i know, is im at less than the reported max voltage for these chips, and that the heatsink is making good contact, and that its stable. 425x8 is my new 24/7, its game stable forever, and orthos for 2 hours at least, before i killed it. so either way, i guess im happy. Well, its good to know at least im not the only one who thinks that its readings are slightly off.

[rodman]

Use the Intel Thermal Analysis Tool

Does not work on my rig

[mach82]

Shows virtually the same as CoreTemp - so in my case 6-7 celsius lower while using P5B deluxe compared to DQ6. This ain't no good.

Hello...
This quite a surprise that this thread got so big so fast.
This program was originally designed to detect the Core temperature of Yonah processors. In Intel's document it says that Yonah can have a TCaseMax of 100C, as in most mobile processors, this value is usually between 95-100C. Then I've found out that all next gen Core CPUs have the same kind of sensor.
What I also found out is that on B0s and some B1s it acted weird showing all kinds of very low or very high readings.
Regarding the TCaseMax, you have to remember, TCaseMax is the maximum temperature the top of the core can get to, Tjunction is the maximum temperature that the junction of the core with the PCB can get to, and that number is usually much higher.
The fact that throttling doesn't start as soon as you pass 85C doesn't say anything.
I've got some reliable info about where the register that indicates a CPUs TCaseMax is located, reading that register reveals weather its a 85C TCM chip of a 100C TCM chip. I guess most/all desktops are 85C, the mobiles can vary.

Regarding accuracy, the program is only as accurate as the sensor which is reporting the temperature, but then this sensor is a digital sensor so it is not prone to interference. The thermal diode that the motherboard reads is, as there is a separate circuit on the motherboard that reads the diode, which can distort the actual readings and make them very inaccurate, add that to the inherent inaccuracy of all thermal sensors and your temperature reading can be very much off than what it is in reality.
In addition as been said already, the DTS is located in the hottest part of the core, while the thermal diode isn't.

[Kango]

Intel's Thermal Analysis Tool gives me the exact same readings as Core Temp does. And both are the same as Everest. Are people saying that these tools are wrong? Then what are we supposed to believe? A linear thermal diode? Or a digital sensor?

After all is said and done, it's your CPU so believe whichever one you want. But keep in mind that high temps can severely shorten your processor's life expectancy. Beware!

[LowRun]

Really, this is hilarious how some people just can't admit their cpu is running hot. They'd rather shoot the messenger for the bad news.
The funniest is when they even admit something seems to corroborate Core Temps results but it, they don't trust it still

[fhpchris]

So then the Intel utility is crazy too? Keep yer head in the sand.

The intel utility does not even run in my board, If you actually believe that those 50c idle and 70c load temps are correct, than the person with his head in the sand is you.

My E6600 @ 1.65v runs cooler than my 1.62v FX-60, and it should as its TDP is less, much less..

The ondie/onboard temp sensors not only need to be Accurate but also Calibrated!

When something has a low TDP, it doesn't have to have low temperature. Core 2 Duos probably have a hot-spot, that is there is a part of the CPU that has high power output while the rest doesn't. Hence the high temperature reported. I believe those numbers, they are retrieved according to Intel's documentation, so if you don't believe it, you are saying Intel doesn't know what they created.

[geforce man]

well if @ 1.38 (lowering voltages and seeing how stable ) im still running 84c, then fine, ill just admit that im actually running 84c. but if thats the case? i dont care. My heatsink is doing its job, and if the proc dies? its loaded voltage is less than stock volts, ill just RMA it.

Man if you really think your E6600 @ 1.65v on air is running at the 38°C PC Probe is showing, you have a serious problem with reality.

Is your chip a B1 or B2 revision?

[geforce man]

there ya go, it only goes up another degree or so after an hour or 2.

[rodman]

This kinda sucks though, I mean there are no real solid programs out there to tell us what Conroe cpu temps are. Here we all are on XtremeSystems (thats people who like to overclock) having no idea if in fact our overclocked cpus are going to burn up or if we could push them harder

How the heck is one supposed to overclock a Conroe rig without being able to use a reliable program to monitor cpu temps. Something has to be done about this

[horrorwood]

What do you have to say about that then?

[geforce man]

HAHAHAHAHAHAHAH sup horrowood, lucky bastage and your 9x multi step 5 e6500. hows that thing clocking btw? yea, im now officially convinced, that right now, something is wrong with coretemp. (and thereby intel analysis tool)
