Conroe CPU and CPU core temp comparison thread

[LikeLinus]

Well I'm screwing around and trying to see how high I can push this E6600.

E6600 @ 370x9.0 = 3300.05Mhz (1.475v) w/ a Big Typhoon

I'm running Prime95 right now (have been for over an hour) and my temps are

CPU 1: 62c
CPU 2: 61c

Idle it's around 45c

Previously I was running it at 3.2 with a vCore of 1.45 and my temps were 50c w/ Prime95.

61c is a bit high, but It's fun testing the limits

 

[T101]

Is it just me, or does the temperatures of the Core 2 Duos seem a bit high? I thought the Core 2 Duos would be on equal terms to the A64 when it came to temperatures. An improvement from the heat monsters previously top of the line from intel. I had expected it to run no hotter than around 45-50C during load, with an idle temperature at least 20 degrees below that. But some here report temperatures 60+C.
Would be nice to know their ambient temperature to get the whole thing into perspective.

The only people who are reporting 60c are those who are running some serious overclocks and overvolting their chips.

Did you read the whole thread or just jump to the bottom?

Sorry, I just glanced over the temperature readings, and clock speeds. Did not check the voltage, which of course I should have (I know very well that higher volt equals greater watt, but was in a bit of a hurry).
Going to build a new setup with a E6600 soon, and was a bit worried about the temperature. I am not trying to start a flame war, if that is what you thought.

 

[talaash]

Ummmmmmmmmm, I am not sure about the readings for temps people are getting, some seem a little high for moderate OCs. Here is my setup and temperature readings: I dont have a program to read each core though, I mainly use Pc Probe 2 and speedfan.

E6600 @ 2.88 on Air, Prime95 and Orthos beta 24 hours burn in, Superpi 32k 17m55s.
ASUS P5W DH Deluxe, 1101 Bios
Corsair TWIN2X2048-6400C4 @ 800MHz
ASUS 7900GT
Seagate 320G SATA II 16MB
2 x Pioneer 111D
SB Audigy 2 ZS Platinum
Chemei 22" LCD
Gigabyte Aurora FSCA1 case
Thermaltake TP 600W PSU with 120mm fan
Logitech X530 Speakers

Cooling:
3 x 120mm fans and Blue Orb 2

Current Settings:
FSB: 320, Dram Frequency: 800MHz
vCore: 1.3875v, MCH: 1.65v, PCIe: Auto,
PCI: Auto, ICH: Auto

Temperatures:

Room Temperature approximately 20-22C

idle: CPU 21C, MB: 42C
Load: CPU 33C, MB: 43C

The load temperature with Prime95 was around 27C but Orthos beta took it up to 33C.

Forgot to mention, I went as high as 3.4GHz, but it was not all stable but temp reading we still under 35C on Load, probably a little more vCore may do the trick and that may account for around 40-43C.

Try using CoreTemp, or the latest Everest.

Ambient around 22C and full load at 33C? Nah. Not gonna happen. At least not with air

Seems we have some scheptics, most people dont seem to consider the importance of teh case in cooling, everybody starts off with "what heatsink?", In cooling the first questions should be "what case?". Here is some proof for you.

Although these temps are at idle, you can see that even with CoreTemp, Core A is at 39C and Core B at 36C. Even with these idle temps doesnt take a genuis to work out the load temps I uploaded above are correct.

I have been running prime95 and orthos as much as I could have in the last 4 days, and decided to reduce the vCore to 1.37 and MCH to 1.55, tested a little to see if it will still be stable. COre temperature according to COreTemp are now:

Core A: 37C
Core B: 35C.

At Idle

System seems as stable as before, but I wont jump to any conclusions since I need at least 24hrs of prime95, memory should be ok I have not made any changes.

 

[Ruhnie]

E6400 on a DS3 @ stock settings

idle temps -

CPU (BIOS/Easy Tune): 35C
CoreTemp Core A: 51C
CoreTemp Core B: 52C

load temps -

CPU (BIOS/Easy Tune): 46C
CoreTemp Core A: 63C
CoreTemp Core B: 64C

So I'm seeing a ~10C difference between mobo temp readings and what CoreTemp reports. Kinda scary.

 

[Baked]

E6400 @ 3200
Vcore @ 1.275
DS3 (F5C BIOS)
Artic Cooling Freezer Pro 7 w/ AS5
Ambient Temp @ 20C
Idle:
Core Temp = 39C
Load:
Core Temp = 53C

Will report back once I get my Thermalright Ultra-120. Will try both Panaflo and Yate Loon fans on it.

First you stated 33C full load. Now it is ... 39C? Or is it 43C? You've got too many figures going around

Also, in that screenie, I don't see Orthos or even SuperPI actually running... So is that 36/39 idle or light load temperature? That I can believe.

e6400 @ 3.19 Ghz (399 FSB)
with 1.375 volts on it (all other voltages on Auto)
mobo: P5W DH Deluxe
HSF: Zalman 9500 AT
Case: Antec P1 180B (with extra 120mm fan on intake and 2 80mm fans blowing on mobo)

My temps, using PC Probe II have always been quite low:
Room temp: 72 F

CPU temp at STOCK speeds: 28C idle, 38C at full load (prime95 + cpu burn in)

CPU temp at 3.19 Ghz (50% O/C): 32-34C idle, 39-41C at full load
(the extra voltage jacks up the temps quickly)

I don't recall my mobo temps exactly, but they are on par with the CPU temps. My apartment is heavily a/c'd and kept from 70F-75F all day long. My case, with all the fan action, is COLD to the touch (not cool, but COLD). I can dial down the fans from high speed to low and the temperature change is on the order of 5C if I just lower the case fans and up to 10C if I let the mobo control the 9500AT's speed. If you have high temps, I recommend you try disabling ANY kind of control the mobo may have over the fans and let them run at maximum. [I have the mobo control of the fans turned OFF and run all but one fan at max speed for my temps, above.]

FWIW, PC Probe and CPU-Z never seem to report the same CPU voltage as I set in the BIOS -- they always appear lower by 0.05 volts or so...

Look Mate, I am just trying to help myself learn, then if I can be help to others, I would be more than happy to share information. You dont know me and I dont know you, so it kind of beats the point if I am trying to mislead people.

In the above statement that you are quoting me its refering to CORE temperatures of 36 and 39C at idle. The 33C in the first post refers to LOAD CPU temperature which are clearly labelled in the posts, and I did mention I was unable to measure CORE temperatures at the stage. I will make a video when I get a chance and upload it so that its more proof. ANd btw Superpi means nothing, I managed to overclock to 3.4GHz and run Superpi and get a result, but Prime95 crashed within 2 minutes, so that really doesnt prove anything. I am not breaking a world record here so give me a break, I have managed to overclock stable to 3.06 GHz, which would hardly amount to anything for someone of your calibre. But at the same time I am not a liar, so please dont label me as such. It gains me and you nothing either way.

I hope I have not offended you, but I think the worst human trait is dishonesty, so for that reason I am a little defensive.

Running at 3.3Ghz (370 FSB) at 1.45v. Temps are 33C idle and 41C Dual Priming. I simply do not trust Coretemp on the Asus board due to its temp being 20+ degrees C over all the other utilities. The Z fan base is lukewarm at best under full load. It has been been running without a hitch for almost a week. Ran prime for only 12 hours but it passed. Memtest passed 2 cycles.

I never called you a liar. I'm just wondering how you're coming up with your temperature figures and by what means, under what load, et al. And you're correct, SuperPI in and of itself is hardly a measure of stability. I just didn't understand how you were stating full load temperatures and then posted a screenshot with nothing stressful running...

I hope I have not offended you, but I think the worst human trait is dishonesty, so for that reason I am a little defensive.

Believe me, it takes a LOT more to offend me

I haven't seen any abnormal results from the ASUS boards vis-a-vi CoreTemp readings compared to the others... I think it is basically a denial thing. "My temps can't be that high!"... You're feeding 1.45v to a 1.325v chip... 1.45+ the Conroes begin to smoke just like X2's do above that threshold. I very much doubt 41C full load. What kind of cooling? And what are your ambient temps?

 

[Tutto]

I just built a kentsfield system and I can't believe core temp is even close to accurate. My idle tems are 37C and core temp is reporting over 60 and under full load I'm seeing temps around 85. I've completed a SuperPI 32M on dual threads and I don't believe if my cpu were near those temps it could be stable. On my e6600 the difference seems to be 20%. The 6600 is running at around 32 on idle and 41 or so in core temp.

Screenshot of my current readings

 

[Pabster]

I don't believe 85C would be stable either. Have you tested for throttling?

These CPUs are f*cked.

I reseated my HSF last night, only for nothing.

The damn CPU's heatspreader obviously isn't flat, as even the base of my Big Typhoon barely gets warm.

I don't want to lap a CPU, as then i'm really screwed if i ever wanted to sell it sometime :frown:

Frickin' retarded that i have idle temps of 45C under default auto settings, which is like 1.15V on my mobo.

Unbelievable.

I'm thinking of lapping my CPU. I'm familiar with the process but not famiiar with the materials necessary to do it.

I just wanna know if it really is just a 'bad' contact with some procs. Cuz thats just crazy it's if as simple as that. Bad QC on Intel's part?? Or what!?!

I mean my X2 on 90nm Core 1- 28C Core 2 - 34C Loads up to 47C on both cores....

I want a conroe but i aint biting until I know some more about these temps....

 

[hags2k]

I originally posted this in another thread on a similar topic, but that thread seems to be dead.

So, from what I've read (http://www.silentpcreview.com/article191-page1.html a good article for example) the readings your motherboard gives can be pretty inaccurate.

Mine are

Idle: 43C
Load: 63C
System/Motherboard: 43C

E6600 stock speeds, stock voltage, stock HSF, 120mm case fan, 21C ambient (according to the thermometer in my room).

I know something is up, because even at full load I can touch the heatsink and it's barely warm to the touch. I also know it's seated well and I'm using Artic Silver 5 thermal compound. I reseated the fan several times, and one time I did NOT get it reseated well and my temps spiked about 15 degrees higher idle. Also, when I ramp up the cpu usage while touching the heatsink, I can feel it getting warmer, but at idle it's practically cold to the touch, and simply gets warm under load, not hot by any means.

The northbridge chipset heatsink next to the processor, in contrast, is VERY hot to the touch. I'm not sure if that's the other temp my bios (and speedfan, which always matches the bios) is giving me, but I'm just guessing.

Also, my system, even with a bit of overcocking (from 2.4 to 2.53 Ghz) continues to be rock-solid stable, using prime95, cpustress test, folding@home, and also when running seti@home and einstein@home simultaneously (which actually gets my cpu hotter than any of the other programs I've used)

So, what do you guys think? Inaccuracies, or perhaps some conroes just like to run hotter than others?

I know the P5B Deluxe reads wrong, and I believe other apps are still wrong too. With that beuing said I've noticed that some people have a concave IHS on their C2D which prevents a good physical contact between the Heatsink and CPU. The only way to fix it is send it in for RMA and hope the next one is good, or lap it and make it flat yourself.
