I have a intel e6600 and zalman 9700 on it with my gigabyte p35-ds4 board.When I open core temp it shows
core1:35 core2:34. Is this normal, and when under load it went 46:45. Is this normal. I read some review at newegg
that so many people said their Core2 idle at 23c and under load never get above 40c with zalman 9700 cooler.So, I need your help with this strange temp.

How thick is the thermal paste layer between the cpu and the cooler?

This is normal... ive got mine idle at ~35c also with Artic Freezer 7

My E6600 idle[on for at least 30 min to let the case warm up] @ 45 :)  (no speed step Load 55)

Damn Sonata II and its super low air flow(5 volt Antec fan and Yate Loon low speed....)....but it sure is quiet :) 

My room temp does not help.....but in a Antec 900 my Q6600 @ 3.0 idles at 38 ish....fan speed 500 rpms...

Moral of the story.....if mine has not died yet....yours will live a long time....

EDIT
If you want to run cooler you can lower the voltage. See what your board runs at. My P5W runs it at 1.325(1.3 hw monitor). Lowering it to 1.225(1.2 in hw mon and as low as the board will go) shaved off some temp and is still rock stable....and at least with your board you will not need to turn off speed step to do so....Notch it down...stress....notch it down stress.......how low can you go......

That said....anyone know of an v mod to lower voltage?

EDIT EDIT
Many people use the motherboard sensors(or in rare cases it may be Tcase) and not the in core sensor for temp readings....those are not accurate....

See the cpu vs the actual core temp....Also room temp has a impact on temps....

It's not only normal it's on the low side. Anybody claiming 23C on air is full of BS or their room temp 50F or less. I have a no holds bared liquid cooling system and idle at 30C with a room temp around 74C with my Q6600. I use Everest to measure my temps. My temps are a little high after trying liquid ice (crap) running distilled water with only additives was around 26C. So you're fine the chip is good for 65C and will throttle back if it gets to hot.

... I don't know about you, but I'll be very reluctant to do anything in a room that has ambient temperature shooting up to 74C.

Sorry, have to point that out, can't help myself. ;)

Guys, remember that there are 2 sets of temperatures; CPU (Tcase) and Core (Tjunction), which always run 15c apart on B2 Stepping processors such as the E6600, so it's very important to be specific. Otherwise, the topic of temperatures is reduced to a blender full of apples and oranges thermal fruit salad.

There's no longer any need to guess, wonder, infer, ponders, suppose, presume, surmise, theorize, speculate or postulate; the answers are in the Core 2 Quad and Duo Temperature Guide - http://www.tomshardware.com/forum/221745-29-core-quad-t... - so check it out.

From the Guide:

Section 6: Scale

Scale 5: Duo
E6x00: Tcase Max 60c, B2 Stepping, Tjunction Max 85c, Vcore Default 1.3525, TDP 65w, Delta 15c

-Tcase/Tjunction-
--60--/--75--75-- Hot
--55--/--70--70-- Warm
--50--/--65--65-- Safe
--25--/--40--40-- Cool

Use Section 9 to test and calibrate your temperatures so you'll know they're accurate.

My new Asus P5E X38 had my E6600 at stock clocks gave me T-case 24C and both cores Tjunction 20C, I just disabled all my T-case reading to [ignore]. It apears that most that have the X38 mobo's are all having the same T-case temp issues, which is why you all should just use "core temps" from now on cause its more accurate.

How was the ambient temperature?

It doesn't matter what the ambient temp is or was because T-case was always 5C hotter than core temp and thats impossible if you on planet Earth. The ambient was at the time room temp 48F, cold it was and has been since.

systemlord, since you already know how to run through the calibrations, why not just re-calibrate your rig? The only problem is that your previous offset in SpeedFan for Tcase was performed for your old motherboard, so it's just a simple matter of re-calibrating the offset in SpeedFan for Tcase to your new motherboard's BIOS algorithms, which are obviously inaccurate.

When I had BIOS 0404, I didn't need ANY Tcase or Tjunction offsets in SpeedFan Beta 4.34, but when I flashed up to 0603, my Tcase was immediately too high. I quickly re-ran Part 1 & Part 2 of the cal's, and found that I needed an offset correction of -15c. Needless to say, I was a little disapointed with Asus in debugging 0603 before they released it. One step forward, one step back. Go figure...

Comp already hit the nail on the head. My point was that the Tjunction might have been right and the Tcase was misproperly calibrated. Tcase should be closer to ambient after a long time at idle.

One other very important point I'd like to make; I would never advise anyone to "ignore" Tcase, unless they understand how Core 2 processor temperatures relate to one another, and had already successfully calibrated their rig. The last thing I want, especially for n00bs, is to think that they can simply "ignore" Tcase, and just use Core Temp, which doesn't always accurately detect Tjunction Max on certain processors 100% of the time. If Core 2 temperatures were that simple, it would never have been necessary for me to write the Guide.

I want to be clear and adamant about this; if inexperienced and unknowledgable users were to accept Core Temp at face value, particularly if enable "Show Delta to Tjunction Temp", this sets up a real potential to seriously overheat the processor. From the Guide:

Section 6: Scale

Sensors (DTS) are used to trigger Intel`s TM1 and TM2 technologies for frequency, multiplier and Vcore Throttling within individual Cores. If Core temperatures increase further to Tjunction Max, then Shutdown occurs. Since Tcase indicates CPU Die temperature only, it is not used for Throttle or Shutdown activation, however, referring to the CPU`s shown below under Scale 1 as examples, Tjunction Throttle temperature is ~ 95c, so Tcase would be ~ 85c, which would far exceed Tcase Max. As Tcase to Tjunction Deltas are constant, Tcase Max is always the limiting specification for temperatures.

Scale 1: Duo
E4x00: Tcase Max 73c, M0 Stepping, Tjunction Max 100c, Vcore Default 1.325, TDP 65w, Delta 10c
E2xx0: Tcase Max 73c, M0 Stepping, Tjunction Max 100c, Vcore Default 1.312, TDP 65w, Delta 10c
E6x50: Tcase Max 72c, G0 Stepping, Tjunction Max 100c, Vcore Default 1.350, TDP 65w, Delta 10c
E6540: Tcase Max 72c, G0 Stepping, Tjunction Max 100c, Vcore Default 1.350, TDP 65w, Delta 10c

-Tcase/Tjunction-
--70--/--80--80-- Hot
--65--/--75--75-- Warm
--60--/--70--70-- Safe
--25--/--35--35-- Cool

Now consider how far Tcase Max can be exceeded on the L2 Stepping processors, when Tjunction is pushed to Throttle threshold at 95c:

Scale 5: Duo
E6x00: Tcase Max 61c, L2 Stepping, Tjunction Max 100c, Vcore Default 1.325, TDP 65w, Delta 15c
E4x00: Tcase Max 61c, L2 Stepping, Tjunction Max 100c, Vcore Default 1.325, TDP 65w, Delta 15c
E21x0: Tcase Max 61c, L2 Stepping, Tjunction Max 100c, Vcore Default 1.312, TDP 65w, Delta 15c
X6800: Tcase Max 60c, B2 Stepping, Tjunction Max 85c, Vcore Default 1.3525, TDP 75w, Delta 15c
E6x00: Tcase Max 60c, B2 Stepping, Tjunction Max 85c, Vcore Default 1.3525, TDP 65w, Delta 15c
E6x20: Tcase Max 60c, B2 Stepping, Tjunction Max 85c, Vcore Default 1.3525, TDP 65w, Delta 15c

-Tcase/Tjunction-
--60--/--75--75-- Hot
--55--/--70--70-- Warm
--50--/--65--65-- Safe
--25--/--40--40-- Cool

As you can see, Tcase would reach 80c, which would FAR exceed Tcase Max by 20c. For this reason, it is niether practical, nor appropriate, nor advisable for any users to dismiss Tcase.

Please pardon me... I've helped so many users correct their temperature problems, that I sometimes can't keep it all straight as to who has run the calibrations in my Temp Guide. I really thought that you had calibrated your rig before your old motherboard died... sorry.

When considering software temperatures, "the majority rules" concept isn't always right. All you need to do is read my Temp Guide Sticky in the Overclocking - CPU Forum - http://www.tomshardware.com/forum/221745-29-core-quad-t... - then once you understand the thermal relationships, just perform the calibrations in Section 9 so that you know for certain that your temps are accurate.

My E2180, and the E6600 both OCed to 3Ghz+ ideals at 23C on air on cold days, etc. and with SpeedStep enabled.......



Well I also have a small pallet of dry ice next to it inside a Copper tube. :lol: 

Edit:
PS: Everest is bad at reading temps(at least most of the cases I have seen) Try CoreTemp or SpeedFan.

Is there a simpler way of performing an offset? I am not willing to dive that deep just to get correct tempuratures, my brain would explode. :lol:  I would have to go back to school just to understand all that cold fusion calculations. :) 

Don't you think that at 3.2GHz full load using Prime95 from an E6600 that temps of 40C core temp sounds about right?
December 15, 2007 6:40:43 AM

My P4 631 65nm 65w idels at 20c according to speedfan and 25c in the bios.

Cooler makes all the difference. I use thermaltake V1 86.7 cfm. Socket 775.

But even more important is Airflow. I was 45 and 50s with a prescott cel D. I got 36c just by using a better case more proper airflow and good fans. Antec P180. Same CPU, just created better airflow. Even all fans on low speed I stll get good temps. And same V1 cooler in both cases.

Good airflow is very important.

Core Temp reads my temps as 55 - 56c on orthos at load for 25+ hours. My load while gaming is 50 - 52c. My idle is @ 32 - 34c in my room, which is usually between 70 and 72f. I see many people claiming that their temps are really low and I do know it is possible, because I have built a system with a zalman 9500, antec 900 case, arctic silver 5, e6600 OC @ 3.2ghz and it idles 25 - 27c, but has its times when it dips to 23 - 24c, which just amazes me. His room is usually around 70f as well and his orthos load is 50 - 52c after 24+ hours. I dont know his gaming load, but non the less I am not sure why his is so much lower than mine. With his temps so low I attempted 3.6ghz on it, but the system wont even make it to windows with 1.5v on the chips and high motherboard voltages as well...just doesnt want to do it. I just wanted to see the temps, but he calls me all the time to brag how his system runs cooler than mine...it drives me crazy. lol, oh yea I think your temps are fine by the way.

Before I overclock my E6600 on my new P5E mainboard my core temps were 25C- 27C at idle, which is around the same core temp as on my old P5B. Now at 3.2GHz my temps are 29C idle and 37-41C during Prime95 session, which I know this is an average core temp for an E6600 at 3.2GHz with a good cooler. Your temperatures are not always going to be 100% correct, but within 15% of 100%.

Just have a look at most BIOS readings, voltages are off by as much as 32% in my case for some voltage readings. My +3.3 volt rail reads 3.25 and my +12V rail reads 11.4v, but at the mobo 24 pin connector reads +12.26v and +3.36v. Some day I hope to be able to read these voltages at a point where there volts are strongest before reaching the BIOS.

  • My Tjunction in Core Temp 85C 29C both cores right now, Speed Fan is reading same.
    I can only guess, below room temp low 60's F. My Vcore in BIOS is set to 1.33v, actual Vcore reading of 1.32v no load and 1.29v under Prime95 stress test. Everest and Speed Fan both read 1.32 Vcore and all three have same readings for core temperatures. They seem to agree with each other.

    Well I did disable Tcase temps because it was reading 5C higher than the core temps which is probibly a bad senser or bad BIOS software issue. I have heard that everyone that has an X38 based mobo is reporting the same strange Tcase temps.
