Sticky: Core i7 and Core 2 Temperature Guide - Page 2

Last message on previous page:
my e6300 is running at 2.2ghz on stock and my tems change drasticly when under load..

speed fan;

idle -CPU =40c
-Core 0 =32c

load -CPU = 69c
-Core 0 =53c

wtf...?

So as not to repost the same things, I wanted to link my question. Your help is aprreciated

http://forumz.tomshardware.com/har [...] 24#1607624

It seems generally speaking core temps should be about 15 degrees higher than your cpu temps. When I run TAT my cores never exceed 54C, but my CPU according to nTune and SpeedFan is at 50C. I have an 6600 that I would like to OC but I don't know what temps to trust. Should I stop my OC when TAT reads 60-65 underload or should trust that speedfan and ntune are correct and not oc?

I have excellent airflow in my case my room temp is about 20C and I am using a Scythe Ninja Rev B.

PS My current idle temps are 34 speedfan and ntune and 39 using TAT.

pls help me out guys, under speedfan: temp1 57c, temp2 36c,temp3 -2c, core0 32c, core1 30c. pls take note of temp1 57c indicating a burning figure on my speedfan page. TAT: CPU0 33, CPU1 31.
my worries is on temp1, is it normal? even at normal clocking still i get same figure of temp1.pls help me.

Hi,

On my set-up I have the opposite of what's expected:

TAT and CoreTemp Report the following Temperatures when idle:
Core0 = 32C
Core1 = 30C
Under Stress this goes to around 50C.

However, PCProbe & SpeedFan report a CPU Temperature of 53C when idle and 71C when stressed.

What gives?!

hahaha

Hello out there, need some help.

First of all let me say I'm spanish and you may found several errors in my english. On the other hand, what a great post about thermal in a C2D. Even though it's hard to be understood due to the technical language, it shows a lot of light to people like me.

Let me explain myself:

I do have an ASUS P5B-Deluxe WiFi mobo with an Intel P965 chipset. I've read there are some problems regarding how this chipset measures temps, so I'll keep this in mind.

My rig as follows:

- Mobo as stated.
- Core 2 Duo E6700 (Not OverClocked)
- 4 Gbs Kingston Hyper X working at 667Mhz
- GeForce 8800 GTS 320Mb

It's summer here in Spain and the room temperature it's close to 30º Celsius.

I'm using Everest Ultimate Edition version 4, so I'm guessing values displayed by this tool are accurate.

When the processor is running @ 1.600 Mhz temperatures displayed are Processor: 52 / Core 1:50 Core 2:50

If the processor goes to full load @ 2.666 Mhz, temperature goes to aprox. 64 /Core 1: 62 Core 2:62-63

Do I have to be worried?

Thanks in advance and thanks for that great post. Apologize any inconvenience and thanks for your time.

of all the programs that report temps and voltages, what program is the most reliable for reporting the correct cpu voltage?
i have everest ultimate edition, intels t.a.t and ntune and they all report different voltages.
i have the bios set at 1.4 volts, everest shows 1.313 core temp 1.31 and ntune shows 1.4

I discovered a new item to cover here...how to do the termal limit testing with Quads. I can only seem to run one instance of TAT, and test only CPU 0 and CPU 1. Is there a way to run 2 and test all 4cores?

Trust your temps?

After playing with a E2180 up to 300x10 (3Ghz, 300FSB) with a Gigabyte GA-P35-DS3L motherboard and testing it a lot, CoreTemp shows it idle at ~36ºC with C1E enabled, same as SpeedFan.

Then I tryed to OC a Q6600 with another GA-P35-DS3L motherboard, C1E enabled, but it got VERY hot, 55ºC idle, 85ºC loaded...
So I spent the day trying different configs and finished with Gigabyte's CIA2 (CPU intelligent Accelerator) set to "Sports" (7%-9% OC acording to the manual, but it does a lot more, like 10%-15%) that was the fastest stable OC with CIA2. And it run a little cooler, but still very hot.
I have it now with "Cruise" setting, (5-7%..) and now I discovered that the CPU may be cooler than what coretemp tells...

Check this out

What software can I trust for Core2Quad?
And if ~56ºC idle is the right one, it seems very hot for me, is it normal?
Any advice?

Thanks!

WEll you can use coretemp for that, it monitors and measures temps on all 4 cores.

To the poster, your advice on shinetsu is spot on, i tried it and get about 3degs cooler at idle, the biggest dfference though is under load, im getting up to 8 degs lower, could, in part be due to a better reseat of my h/s but it wouldnt be that different, so thanks.
[cant get my head around the details of the guide though tbh]

Hi ... thanks for that great thread..
But I have a weird thing !!!

My system is Gigabyte 945P-S3 rev3.3-C2D E6420-2GB 667 ram-Geforce 7900GT PCIexp

I have the Tcase is HIGHER than Tjunction1 and T junction2 !!!

being for ex. 43c/32c---33c !!! is this normal at idel ? my system is not overclocked or something ...everything is at stock ...

And during gaming ..is hitting the 50c in any parameter is bad or not really bad ?

by the way...I didn't apply any thermal paste during the CPU installation and I'm using the stock intel fan cooler..according to the buyer , It doesn't need thermal paste cause the cooler contains it at the buttom !! Is this true or I should use a thermal grease ??? thanks in advance...

I am running my q6700 at stock speed, and when doing this torture test in prime95, my cores goes up to about 66-67C.(34-35 idle) Is this a safe temp? btw I am using the Thermaltake MaxOrb CL-P0369 cooler, and could that be the cause of the problem? Also, I probably wont stress the cpu as much as in prime, so I guess i wont reach those temps outside that prog, and does that mean the temp is safe?
All help appreciated.

ok. i have a question - are you guys really really sure that M0 stepping of E2XX's have to add 15c to CoreTemp's readings? because this makes no sense - i'm running TAT at 100%, it's saying 59/54, if i add 15c that would be 74/69, it should be throttled already, but it's not, and my CPU heatsink isn't even warm to touch! something is terribly wrong here..

Very helpful guide. Now I can actually trust my SpeedFan temp readings.

E6750 @ 400x8 (3.2Ghz), 1.35V
Antec 900 Case
CPU Cooler = AC Freezer 7 Pro (set to ramp up to 100% as temp approaches 40C)
Ambient = 22
Tcase Idle = 25, Load = 40
Tjunction Idle = 32, Load = 50

Love the temps, now I can finally sleep fine w/o worry...

Hi there. i´m sorry but still confuse with temps. i don´t know wich software to trust, wich is my limit temps, etc.
i´m doing some overclock and what i want to know is wich are my safe temps and where should i stop pushing.

I have an intel e2160 Dual core 1.8Ghz CPU (Stepping 2 Revision L2) OC at 3.0 Ghz
According to your article my temps should be(1):
75-75 - Hot
70-70 - Warm
65-65 - Safe
40-40 - Cool

Ok. Temps Reports are:
CoreTemp SpeedFan Intel TAT
Idle 45-42 27-27 47-45
Load TAT 71-70 54-54 70-68

So wich should i compare to (1)?
lots of thanks

"If temperatures don't meet Parameters, then SpeedFan 4.33 can configure Offsets to correct for Tcase (CPU or Temp x) and Tjunction (Core x). From the Readings tab, click on the Configure button, then click on the Advanced tab. Next, click on the Chip field directly under the tabs, then use SpeedFan's Help and HOW-TO icon included in the installation Program Group."

i dont understand that.. i have a Q6600 with G0 stepping and i dont see any how to.. could someone maybe give me a step by step on how to do it please

This guide is exactly what I needed to understand the relationship between Tjunction and Tcase on our C2D, C2Q processors. However the guide is now missing sections 6 through 16: "SERVER EDIT MALFUNCTION ... REMAINING CONTENTS TEMPOARILY UNAVAILABLE ... PLEASE TRY LATER." Is this archived anywhere that I can retrieve it? Thanks!

The google cache page has been "updated" to the broken guide now, damn you google!

@CompuTronix: You should do a temp guide on the different chip sets (ie, P35,X38,680i,etc) also if possible.

i'm sort of confused. from what i understand, there is a possibility my temp readings are inaccurate.

so i grabed a thermal gun and scanned the ambient temp while the system is off and it read 18C. with that, should the Tcase automatically be 19-22C? and based on that temp, should i offset speedfan to be +5 of tcase?

thnx

^ Agreed with Comp.

@Steve_long: This guide is meant to provide very detailed information. If you can't handle the details you should look else where.

Random thought:
Comp, what's your take on RealTemp?
http://www.xtremesystems.org/forum [...] p?t=179044
PM me with your thoughts.

I agree 100%

I think most of the people saying "great guide" are just trying to sound smart. This is rubbish, Everest is WAY better than speedfan.

I mean how in the world am I supposed to calibrate this.


I will continue to completely ignore Speedfan and stick with CoreTemp.
