liars! core temp? real temp?? asus probe???

[FragMan]

i dont know who to believe lol i know i have to cool my board more its stable @ 3.2 overclock. but who's the closest to true readings?

Real Temp will give you the correct readings.

That's actually not really correct. Here's a good explanation of the situation. http://www.hardforum.com/showthread.php?t=1326875

WOW! thanks for the linkies!!!
so........ lemme see. forget what readings are for a moment .. let us instead use the Tjmax to gauge how much hotter till melt down ! LOL not bad. i like it.

Kirk: Scotty!! We need more powerr!
Scotty : We kinna do it Capn, the dilithium crystals will melt down in 20 seconds!

Real Temp is as close as it gets to the real thing. Core Temp reports the wrong estimated TJmax values for 45nm C2Ds, but Real Temp uses the estimation of 95C, which seems to be correct. There's no real confirmation of what the actual values are, however based on the extrapolations done by people in the know, these are the most accurate values you can get. Therefore, I recommend Real Temp over Core Temp and other utilities for those who have 45nm CPUs, since although it won't give the absolute certain readings, it'll give the most accurate numbers that are possible with the information that's out there.

RealTemp is the real deal.

Even for people (like myself) running something other then a 45nm chip...the TJmax can be very easily altered in RealTemp to adjust temperature readings...I love the app.

hey I never knew that the asus rampage supports xeon processors!!?!!

...and here is one of the big problems furher making it harder to compare temps. A lot of people "calibrate" there temp reading, which usually means knocking the temp down. Then they post comparison temps that are like 15C lower than other people, boast about their cooler/case/OC skills, others scratch their head...

Exactly !!!!!

Anyone wants to impress me, and I know of no good reason to try, I want to see "Delta to Tjmax" under load. What use is a computer at idle anyway ?

Idle temperaturs mean nothing obviously...and because RealTemp lets you modify the TJmax
you have to make sure people are listing what they have it set to with their results, as it doesn't display it on the main program window.

what a Klusterfaak of apps. I'm now more upset that my unaltered Real Temp has a tjmax distance of 28c for my 3.2 Ghz overclock, which in short tells me Im running way too hot now

Tired of paying big bucks for expensive HSF? Can’t afford a nitrogen cooling system? Well now you don’t have to! Announcing “CoreTemp Magic”. “CoreTemp Magic” is able to reduce your reported Core Temps through a simple application. Here’s how it works. Let’s say you are seeing Core Temps of 70C under load, well simply, through the “CoreTemp Magic” application, change the value of Tjmax from say 105 to 95 and your reported temperature will drop like magic! Now you can keep on overclocking! Wow that was simple! Be careful however, because if you reduce Tjmax to 35 or less you can expect ice to build up on your CPU under load.

I posted the above previously when this topic came up. The point is simple, no one knows Tjmax for Intel desktop processors becuase Intel doesn't publish it. Intel did provide Tjmax for their mobile parts and folks tried to use that actual data as a basis for the desktop processors. But its a guess and you can change Tjmax in your app it to what ever you want. That is why if you want "core temp" to report the same temp as "real temp" simply set their Tjmax to be the same. They use the very same mechanism.

I had this same argument with my 65nm E4300, Coretemp read way high (100C Tjunction) and real temp read 85C default for this chip. The author of Real Temp states in another forum that this chip is correct with 85C. I am apt to believe him based on IR thermometer readings of my vendetta 2 under load (3.3Ghz oc at 1.51V) I have another thread in this forum that discusses my experiences. Needless to say, II like my current idle temp of 32 C in a 27C room. I think this is far more believable that 47C idle for this chip and the cooling structure I have.

It's true that they use the same mechanism, but Real Temp automatically uses the value for TJmax that's assumed to be correct for 45nm processors, so you don't need to manually change anything. The default readings from Real Temp are more accurate than those given by Core Temp.

From analysis of chips where Tjmax was published, Tcase was ~5C less than calculated "core temp" at load. An IR thermometer test should yield Tcase +- 2C.

Best way to monitor is through a hardware based monitor or 3rd party Zalmon set or just simply your BIOS for the REAL temps!

 

[BillParrish]

simply your BIOS for the REAL ...

er, ah, hmmm, NO.

Umm...not quite...more then half the time the BIOS gives some of the most squed CPU temperature readings, as it'll just be using it's own diode as opposed to software like CoreTemp/RealTemp that read from within the processor itself.

It's entirely true that nobody actually KNOWS the TJmax values for any of these processors, Intel doesn't publish it...so the closest/best thing we can do is our own research to see what makes more sense for each core revision. My E4300 that I had was a newer core revision at the time and the latest version of CoreTemp was reporting that at 1.8GHz and a 20c room temp the chip was 20-25c above room temperature on IDLE. Cases like that can lead you to believe one piece of software more then another and it's all we've really got to go on.

The one main thing that should come of this discussion is that CoreTemp/RealTemp are the most accurate applications out there for temperature monitoring, you just have to know what TJmax value to base the readings on.

NEVER use software that came with your motherboard unless it is actually right in line with CoreTemp/RealTemp to begin with. Furthermore, don't use the BIOS at all...sitting in the BIOS your processor actually has a small amount of load but on it, single core processors can see equivalent temperatures to being under almost 50% load in windows. It's not possible to get a true idle temperature reading from the BIOS to begin with because of this...another reason why it shouldn't be relied on for CPU temps.
