Ok this is quite a simple question. I have SPEEDFAN and CORE TEMP.


Speed saids Temp1: 48c Temp2:37c Temp3:-1c HD0: 33C Core0: 41C Core1: 40c


Core temp saids 56C core 1 and core 2 55C

which one am I supposed to believe? I have my e4300 oced at 2.4ghz was 2.7 but i lowered just to be extra safe. Any ideas? thanks a bunch
April 28, 2007 9:25:48 PM

I use core temp, b/c speed fan won't work on mine. I think core temp takes the temp from the tjuction, and is a better indication of the hottest part of your processor.
April 28, 2007 9:54:23 PM

soi is my temp fine? cause non clock its still 55c according to core temp

Can't find your answer ? Ask !

yea, at the tjunction it can get up to 75C before you realy have to worry at stock speeds, but even at the overclocked speeds your at, your temp is well within the green.
April 28, 2007 10:01:08 PM

You are probably using core temp 0.95. For some reason it reads 15C too high. Try using core temp 0.94. That should match the speedfan tempertures.
April 28, 2007 10:39:50 PM

where can i see my tjunction temp? I wanna hit like 2.8ghz or 3.0ghz with stock cooler and have stable temps if thats fine also in speedfan the Temp1 thing saids 52c and has a fire picture next to it....is that really high? also how far up can i go with stock voltage on the e4300 and if i need to increase then how much to reach 3.0ghz like what would the total Volt be?
April 28, 2007 10:52:53 PM

The temp I get on core temp on my computer is mesuring from the tjunction, but make sure you have v0.94.
April 28, 2007 10:57:52 PM

ok wait wait my temp according to core temp .94 is 43C and 42C so then i can push it up til how far? whats the highest temp i should hit? and also u have any idea why in speedfan temp 1 is on fire?

It is on fire because of the settings in SpeedFan. In the configuration settings it has a specific temp that is preconfigured as too hot which activates that fire symbol.

Is 43c your load temp, if so what are you using to load the CPU?

From CoreTemp (.94) you want to stay in the 52-55c range, anything over 55c tends to be on the hot side.
April 28, 2007 11:18:56 PM

oic i looked more into the temp 1 and its my system temp overall...so is 52c to hot for all system temp?

43c is my temp on cpu both cores when im playing battlefield 2142 and installing patches or having music on. according to coretemp .94 so then i can oc up to 50c or so on load but what about system temp whats a good overall system temp?
April 28, 2007 11:25:02 PM

If your going off the tjunction temps then about 60C or less should keep you well within temps that will give you good life for you CPU when your ocing as far as you want too.

Now for over all about 50c to 55c, but that is general temp not the core themp
April 28, 2007 11:33:06 PM

Yes, Core 0/1 can get to about 50c and it won't hurt the processor.

Temp 1 for me is Tjunction, not overall system temperature. Hmm.
April 28, 2007 11:41:42 PM

ok well i got these temps Temp1 fire 50c temp2 40c check temp3 -1c blue down arrow hd0 37c blue down arrow core0 44c check core1 43c

is urs somewhat like that? because if temp1 is my tjunction is 50c alright?
April 28, 2007 11:46:39 PM

all those temps seem normal.
April 28, 2007 11:48:56 PM

fantastic !!! so whats my max tjunction i should go to?

Tjuntion is fixed and if you reach Tjuntion your processor will modulate (throttle) or shut down

True. Imho, Tjunction shouldn't exceed ~70c. It is a conservative view, but that is my limit of comfort (hey, I am an accountant, what can I say :tongue: ). I know the spec allows it to go up to 85c, but I am not comfortable with that.

I actually have 3 or 4 monitoring programs reading off temps/voltages just so I get all the information. 8O
April 29, 2007 12:19:55 AM

what superfly03 said is about my answer, but since your already over clocked and your aiming higher, and because of that more voltage less heat thing for the longevity of the chip, set 65c as the stop point and you'll be fine.
April 29, 2007 12:31:34 AM

Your motherboard monitoring software should suffice.
Just keep it around 60ish max load max temps.
Under normal computing you’ll never hit 60C.
Orthos will give you a good overall bench burn in with blend mode priority 9 after you have determined your max CPU temps
April 29, 2007 12:38:22 AM

I sure hope you are talking tcase with that 60c... :wink:
April 29, 2007 12:42:05 AM

yes Tcase 8)
April 29, 2007 3:34:57 AM

great!! u guys were a bunch of help!! at stock voltage im at 2.8ghz w00t and only 55C max with battlefield 2142 running, adware running and scanning, and anti virus scanning!!! great job everyone thanks a lot

I'll throw a bone out to everyone.

Chip: E4300 (stepping: 2 L2)
Code: L702 C567
Clock speed: 3267 MHz
Voltage: 1.475V, bios
Cooling: Scythe Ninja Rev. B + 85CFM 120mm fan (~70% more airflow)
Mobo: P5B Deluxe 1.10G

Ambient: 29C (it is frigging hot because of my 8800GTS, small dorm room, and P4 3.0 + 6800)

Orthos load:
Tjunction: 90C (Core Temp 0.95)
Tcase: 63C (SpeedFan)

Idle: [tentative numbers from what I remember from a few hours ago]
Tjunction: 4xC
Tcase: 19C [suspect]
Waiting until 4 hours (ie. 1h 25m from now) on Orthos before getting real idle temperatures.

From what I can see, this E4300 is a slightly-below-average chip, requiring 1.475V to hit high 3200s.

My E4300 at 1.475V (bios) 3267MHz is getting 90C in CoreTemp 0.95, but ambient is like 29C right now.

In case you didn't realized, that CoreTemp 0.95 seems to be useless:

In case you're to busy to read it all:

According to one of the more interesting threads I've read in Intel's open Dev forums, a very unpleasant picture arrises. Desktop/Server CPUs DON'T have a constant Tjunction temperature, unlike many Mobile CPUs which contains the Tjunction information in bit 30 of MSR 0xEE. This value is either 85/100. Possibly by a mistake, this value seems to exist in the desktop processors as well, but this does not make it valid at all.

I read it, but 75C (0.94) or 90C(0.95), the CPU is running ridiculously hot.

I swapped out the anemic stock fan on the Scythe Ninja and replaced it with one that had about 70% more airflow, and temps dropped only by 1-2C. I suspect mounting errors, but I'm running a 4 hour Orthos test right now for [H]ardForum's Conroe OC database and can't fix the CPU cooler.
April 29, 2007 4:50:27 AM

Well, your ambient IS hot, but these figures seems too big. Are you sure your HSF is mounted fine?

Aw please, I'm going for max OC (ie. 3276, or 1MHz higher on FSB, isn't stable!) at my highest confortable overvolt (1.475V) :-D

Gotta get those e-penis points for placing 5th here:

about my tjunction....is 86c to hot? what should be the highest it can reach before danger zone?
April 29, 2007 6:16:33 AM

I remounted the HSF and found an air bubble right over the core in the thermal paste. At 1.425V 3168MHz, I see 77C in TAT, a little better than the 83C I was seeing earlier.

EDIT: Okay nevermind. I just saw 79C, which means there isn't any real benefit yet. I better lap my E4300, or maybe remove its IHS. Goodbye, warranty.

It depends per processor (ie. Core Temp 0.95's Tjunction is *wrong*), but generally you won't get to the danger zone before the processor throttles itself (which is probably around 90-100C for the E4300). If you disable throttling, the CPU will cut off to save its hide around 135C.
April 29, 2007 6:36:15 AM

I know most of you know this but I see a lot of you are getting it wrong
Core temp, the software program isn’t so complicated that you need to do more calculations to arrive at your correct temperatures.
The calculations are done for you and they are done like this.

T junction minus the actual temperature which is in degrees negative away from Tcc activation read at a specific MSR through the PECI
T junction in theory is a fixed number read through a specific MSR that is at the point where TCC activation is set and the processor modulation occurs by means of Vcc reduction and or processor multiplier reduction until the processor returns to an acceptable temperature.

When T junction is 85C and the reading from the DTS is negative 30 the calculated temperature is 55C and thus reported by Core temp.

When the Tjuntion is 85C and the DTS is negative 10C this is considered Tcontrol and maximum fan speed control is commanded at 66C.

For the higher wattage processors the Tjunction is elevated and like all processors is a fixed number set during the manufacturing procedure per package.

T case the temperature reported through the PECI from the thermal diode or the temperature dead center of the cpu on top of the heat spreader



The newer processors have only the Digital temperature sensors and the thermal diode has been eliminated so this will be more fun for you guys trying to calculate your temps. :wink:
At a later time I will post an update for this new thermal management package.

TjMAX minus DTS delta actually. But it's invalid for C2Ds. Here the calculation is PROCHOT minus DTS delta. And PROCHOT is unreadable by software. You can only provoke thermal throttling, to see when it comes.
April 29, 2007 3:13:02 PM

Thermtrip signal is the temperature where all bus traffic is blocked and the system is shut down to prevents failure.
The point of interest is TCC which is numerically not software readable but is an assertion point or you would see the proper temps on the E4300.
I’ve posted this before with a link directly to the Intel forums.
Prochot is a reference point and is part of Tcc activation
Thermtrip is catastrophic failure

So I've said. There is no software tool to read temps from C2Ds.
April 29, 2007 3:55:27 PM

:lol: 
But that is where the conflict is .
every one is overclocking c2d's
the mobile platform responds well to core temp and TAT
April 29, 2007 4:03:55 PM

I think it was nearly true for b2 chips, now it's not.
April 29, 2007 4:06:25 PM

correct.
the newer thermal package will introduce very accutate temperature monitoring providing the support is included :wink:

April 29, 2007 4:39:14 PM

I have been following this for awhile and careful to respond as of yet.
The data sheets are updated and I am trying to gather as mush info as possible to decipher this correctly.
As of now this subject is well debatable
April 29, 2007 4:45:13 PM

Keep us informed, please.
April 29, 2007 5:06:10 PM

As you can see below the PECI will be used for thermal management and fan speed control.
Same concept only without the legacy thermal diode and therefore the margin of error is greatly reduced.
This is already implemented on the Q6600 and later packages will be entirely dependent on this method for thermal management.
As before this function has to be enabled in bios and supported in the bios revision


April 29, 2007 9:36:57 PM

ok quick question now...my e4300 is at 2.7ghz and temp is about 60c load with prime 95 with that turtore test thingy...in core temp it saids 60c but my tjunction is 85c is that to high? cause when on stock it still saids 85c...

CoreTemp doesn't actively report Tjunction, just the max spec allowed.

60c is getting kinda hot, is that Coretemp .95 or .94?
April 29, 2007 9:48:07 PM

core temp .94 beta according to the bubble window that pops up if i click it...what if im getting 43c and 41c just watching a movie or playing a game thats no big deal right....cause temps only go up if i do the prime95 thing....also any ideas whats the safest max fsb i should go to with stock e4300 cooler? cause for a week or 2 ill be using stock then getting Tuniq Tower 120
April 29, 2007 10:14:50 PM

ok with max load with prime 95 and all that plus winamp running is 57C max and that only hit that once average is 53-55c is that fine for a while? What steps can i take to reduce heat? I got a sideiwnder case with two 92mm fans one in back on in front and thats all it supports....should i buy those pci slot fans? what about thermal paste? should i replace the stock with some artic cooler paste? and whats prolly the best cpu cooler? hopefully all my oc stuff will be done by tonight so no worries lol...thanks for replies
April 29, 2007 10:29:39 PM

Shin Etsu X23 (i think that is the official name) is the best thermal paste, Thermalright Ultra 120 Extreme beats the Tuniq Tower, and those temps are probably as high as I would go given your current cooling. Just keep an eye on your temps and as long as they don't go above 55c on average, you can expect pretty good life out of the processor (if your voltages aren't nuts like mine).
April 29, 2007 10:47:12 PM

my volt is stock aka 1.325v ya on average its 52c ir so and will be lower with cpu cooler lol....to bad i just bought some 5.1 logitech speakers so now my cpu cooler will have to wait like 3 weeks....so thats no big deal right? i mean 52c average should be fine for atleast 2 years or something i hope =)
April 29, 2007 10:51:30 PM

quick update temp on prime 95 torture test ranges from 52-57 and is usually 54 to 56 thats fine right long as nothing goes above 60?
