Collecting Core 2 Duo CPU temps for analysis

[turpit]

With all these apparent disparities in Core2Duo CPU temps, I would like to ask for your help in collecting some data. I know its a lot to ask, but if people post, I will correlate the data into a spread sheet and look for trends/patterns to try and identify why we may be seeing monitoring program temp disparities.:

[EDIT] due to the long load times, bandwith, and general pain for involved for folks, I am no longer requesting screen shots.

I request that you run these specific programs:
Core Temp: http://www.thecoolest.zerobrains.com/forums/viewtopic.php?t=137
Intel Thermal Analisys Tool (TAT) http://shintai.ambition.cz/files/tat.exe
Speedfan: http://www.almico.com/speedfan.php

These programs would also be extremely helpful if you could find the time

Hardware Sensor Monitor: http://www.hmonitor.com/
Mother Board Mentor 5: http://mbm.livewiredev.com/

PCProbe if you have an ASUS mobo (comes on mobo disc)


I would like:
-temps at idle
-temps at 100% load on both cores.
-Ambient (room) temperature

To load the cores, please use CPU Burn In: http://users.bigpond.net.au/cpuburn/
set to "Disable error checking-maximum heat generation". This WILL NOT harm your CPU

You will need to run 2 instances of Burn in simultainiously to achieve 100% load on both cores


I would ask you include the following information:

(Some of this info can be found using CPUID http://www.cpuid.com/ )

Motherboard
-manufacturer
-model
-revision
BIOS
-type
-revision
- Q fan disabled or enabled -setting if enabled
CPU Heat Sink Fan/water cooling
-manufacturer
-model
CPU (Core2Duo obviously)
-version
-revision
-step
How you took the data, i.e case closed, case open, open air(mobo not in a case)
Case manufacturer /model

Any other pertinant data i.e "my case has 15 120mm fans, running dual Nvidia 7950s etc"

 

[Assman]

E6400 @ 3200 8*400 1600fsb
Zalman 9500 CNPS
ASUS P5B BIOS 0509

TT Armor Case
2*120mm fans (intake, exhaust)
2*90mm fans (top, exhaust)
NB active cooling

@ Idle 43-44C cpu, 38C mb

@ Load 48-50C cpu, 38C mb

Thanks for the response

 

[Assman]

anytime buddy, keep us posted with the spread sheet

 

[itneal2277]

Most of the info you need is in the sig and the pic. The bios version I'm using is F5. My heatsink is the Thermaltake Jungle 512. I have turned off fan control, thus leaving the cpu fan at max speed. My case is filled with 120mm fans, so if there is a place for a fan mount on the P180, I have a fan installed. The case was closed at the time of the readings. Also, I am using AS5. If there is any additional info you need let me know and I'll try to get it to you.

 

[turpit]

Thanks very much for the reply.

I will post the collective data as I get it organized

 

[aequalsb]

I've rounded up some readings for you, didn't use those programs cause i'm trying to keep this PC Bare minimum. I think the data is useful though being as it's similar to the other readings i saw..

Stock HSF, Antec Sonata II, w/out duct. One Huge fan in the back on High. 7600 GS (runs w/out a fan and probably adds heat to the whole senario) Ambient is usually 26-28C (80 F)

 

[nukemaster]

IDLE

LOAD

Please note my case was open for this....i just installed ram....
Will post again with closed results

Specs in sig

 

[litlcrochunter]

P180B - 3 120mm in upper chamber
Active NB cooling
Zalman 9500

Ambient is roughly 22 degrees celcius.

Idle


Loaded




If you need anything else, let me know.

 

[turpit]

thank you very much for your input

 

[turpit]

Thanks for your input

 

[turpit]

Thanks for your input

Perhaps having some info about the PC's setup will help w/ the data. Case setup, Water cooling, Air cooling, ambient temp. You think?

Yes, and I did, though its at the bottom of the OP

 

[turpit]

Hang tight, I will get you Core Temp, Everst, and TAT for sure, on X6800 at 2.67, 2.93, and 3.2 GHz and 1067 FSB.

Also, get this stickied at the top and summarize the data.... finally, see if you cannot solicit ambient temperatures, this makes a big difference.

Jack

:lol: :lol:

Yup.

Typical of me...I was so intent thinking about what little things might have an effect, that I overlooked the forrest for the trees and FORGOT TO ASK FOR AMBIENTS!!!!

WHAT A DUMBARSE I AM!!!!!

 

[nukemaster]

Idle(closed case)

Load(closed)

Note.....I was getting 64(just a week or 2 ago)....i guess the AS5 must have set or something....If you want full fan speed just let me know...

Also good to see most people with air get the same as me....

EDIT

room temp 23-24 ish....if i trust the thermostat that controls the furnace in winter

 

[turpit]

Just a some little improvement to make your survey better cuz I'm intrested in the data too.

CoreTemp, TAT and Everest reports all with 1-2C of each other. Ding, TM2! Those are one that's worth reporting.

Speedfan: http://www.almico.com/speedfan.php
Hardware Sensor Monitor: http://www.hmonitor.com/
Mother Board Mentor 5: http://mbm.livewiredev.com/
And the software that came with your mobo caculates through TM1 and maybe some other sensor which I don't know about.
Conclusion: Not worthy data from those above listed monitors

Other than those I think your survey would be perfect.

Wusy, you are right, but there are a couple of reasons I want the other numbers too.
One is some of the bizarre differences in mobo temps relative to CPUs temps Ive seen. The other is the guys who are seeing the same temps from PcProbe and TAT/CoreTemp....They shouldnt be

To be honest, with all the stuff Ive seen over the past couple of weeks, Im not seeing a 100% solid pattern. Everytime I think I see a trend starting to solidify, someone else comes along and posts some new numbers that errodes the theory, so, at this point I dont want to disregard a lot.

I had to force myself not to ask for ram, PSU and HDDs too. Even though these should have no apparent effect, just their physical postion in relation to the CPU HSF might have some effect.

I just dont know, so Im grasping at straws and looking for all the data (reasonable) I can link to look for a pattern.

As I get the data asembled, Ill be posting here so you and the rest of the experts can look for relations I may be missing. Im really just trying to do the secretarial work so the smart folks can look at the data.

 

[aequalsb]

sorry man. I'll redo my post and maybe play w/ those programs you listed... For SCIENCE!

 

[turpit]

Thanks much for the input!

 

[aequalsb]

Thanks much for the input!

Couldn't get TAT to run, i seemed to get the cpu hotter when i tried to max it out w/ a virus scan while i tried to compress 700MB at the same time. Still have those old values if needed.

[nukemaster]

nice temps....what cooler? case?

 

[turpit]

Thanks much Jack.

 

[qurious69ss]

Sorry haven't figured out how to add pics. Anyways, my idle temps are around 34C but at load my temps go up to 61C after about 45 seconds, after a minute temp jumps to 62C. I stop there since I get worried about damaging the cpu. By the way I'm at stock speeds and using a Zalman 7700 AlCu heat sink at full speed.

Temp monitor: Probe and Core. They both read about the same.

 

[qurious69ss]

Thanks Jack, I will post my numbers tomorrow since I'm currently at work. By the way, I see that you didn't use the recommended way of installing AS5 ( website instructions), but yet you got great temps. I tried to spred it the way that you did, but it didn't work for me. Temps actually went up 3 degrees. Could be my heatsink. Also have your temps dropped any since you installed it? I hear that after a week that my temps should drop 2-5c. Well I'm happy with my idle temp of 34C, just my load temp of 62C that sucks.

 

[13thmonkey]

I assume you want any thermal management from the mobo turned off? i.e. you wants its stable temp, my fan is set to speed up at 45C and that'll drag it down even under dual prime.

Will probably have to post tomorrow. We'll see how the cheap ass mobos hold up.

 

[qurious69ss]

I see, I just used 100% IPA to clean the heatsink and cpu. I'll try the distilled water and acetone next time. What I don't get is why my idle temp relatively low at 34C and my load temp so high at 62C. That is a 28 degrees delta. Well EIST is enabled so at idle my freq is at 1.6ghz and 1.14v, at load freq jumps to 2.6ghz voltage 1.24v. Could it be a bad cpu? It is a ES and I could exchange it for another one, just don't want to go through the hassle if it's not that.

Put it under TEC+water or phasechage or SS and make good use of that 12x multiplier which isn't avaliable to retail E6700.

Well I can't see myself spending that much money to cool down a pc. Heck I reused everything but the MB from my last build. So you think I need better cooling, any chance of the cpu being bad?
