When overclocked to 3.0Ghz on stock hs/fan with stability my core temperature goes up to like 80 degrees celsius and cpu temp to 60 celsius.

On idle without overclocking, core is like 45-55 and cpu is 33-35.

The core 2 duos' core have similar temps with cpu. what's wrong with my quad cores?

my cpu is Q6600 G0 stepping.

Help, please.

You have a heat problem there, that's much too hot. Try reapplying the thermal paste: http://www.arcticsilver.com/arctic_s...structions.htm

Below is what Intel replied to me;

Thank you for contacting Intel(R) Customer Support.

I understand you are looking for information on the operating temperature of the Intel(R) Core(TM) 2 Quad processor Q6600.

You do not need to worry about the temperature of each core, you only need to pay attention to the temperature of the CPU it self.

In order to lower the processor temperature we recommend using a thermally advantaged chassis. Please check the following website to identify a thermally advantaged chassis:
http://support.intel.com/support/pro.../CS-008537.htm

A list of tested thermally advantaged chassis is available here:
http://www.intel.com/cd/channel/rese.../eng/53211.htm

We also recommend having the latest BIOS version for your motherboard.

The maximum operating temperature of the Intel(R) Core(TM) 2 Quad processor Q6600 is 71 degrees Celsius. As long as the processor is operating under this temperature it is operating within specifications. We do not have a normal operating temperature for the processor as this temperature will vary depending on the chassis and other hardware installed on the system as well as the actual load the software is placing on the processor.

You may verify the thermal information for this processor here:
http://processorfinder.intel.com/det...px?sSpec=SLACR

Since your CPU is running at 59 degrees Celsius, and the maximum recommended temperature for your CPU is 71 degrees Celsius, it means that your processor is running under specifications; so there is no reason to worry about the temperature of your processor.

More information on thermal management is available here:

they always reply the same to everybody... i have the same mail when i asked them for over heating my q6600... but later i found i was having a faulty DP35DP mobo..

stressfreesoul

They are basically rattling on one of my usual lines. Good airflow is a must!!
You should ensure that...
a) the only objects in the flow of air, should be those you wish to cool!!
(this means routing cables, using rounded IDE data cables, etc)
b) use as high RPM fan as you can bear the sound of (cheap high speed fans are loud, this Noctua fan is a good example)
c) plan your airflow carefully! (a general, front to back, unimpeded design with extra for a graphics card if you have one)

FreoHeaveho

The Q6600 with the G0 stepping can go to 3.6GHz on air easily. I would suggest you have a lot more in the CPU. Also, what program are you using to monitor temps? It may be worth checking the bios temps, which are more accurate.

tandav

I'm using Everest Ultimate Edition.

I've now put my CPU to default speed. I won't change until I get a good CPU cooler. I'm thinking about getting Asus Silent Knight Cooler.

Is there any disadvantage of running the CPU Fan at full speed all the time when i'm using my PC? At full speed, the CPU temperature goes down to 33 when overclocked but the Core temperature are like 50 degrees Celsius.

I have a PSU with Dual Fan and two other fans that have blue light (One at front and one on the side.

FreoHeaveho

The only disadvantage of running at full speed is noise. To be honest those temps are fine. The Q6600 is famous for its overclocking ability.

I have only SATA cables, no IDE, the DVD writer is converted to SATA.

I can bear the sound. I ran couple of times, but at night it sounds too loud.

My Core # 4 is always with higher temperature by 10 degrees from the lowest one which is Core # 3 and Core # 1 and Core # 2 have the same temperature all the time (may differ by 1 or 2 degrees.

My motherboard is Asus P5K-SE/EPU, Graphics Card is nVidia EN8500GT 512MB.

Both HDD and DVD are UDMA enabled.

When overclocked, I noticed slower in performance, kind of freezes for sometime, but has never crashed yet.

Thanks!

Those temps listed are on idle state.

I checked today by running the stability test for 10 minutes on Everest Ultimate Edition and the Highest Temp of a core was 83 degrees Celsius and CPU temp was like 60 degrees Celsius.

stressfreesoul

How have you been overclocking it? By manual adjustment, or an OCing facility/program/auto setting?
That sounds to be unstable if it sticks and core temps are that high. Mine is also G0 and I have NEVER had over 65 celsius core temps, even under massive load. Please check BIOS for your Vcore power value and any other settings you may have changed whilst overclocking. Also have you checked your thermal compound and that the CPU cooler is seated properly?

tandav

I did from the BIOS.

Well, sometime it looks stable but sometimes just freezes for few seconds.

Core #4 and 3 have the highest temperature and Core #1 and 2 have like 73-75.

I think it is due to the CPU cooler not being seated properly. i checked couple of time, but looks fine and i even tried placing in a proper way twice. i have removed the HSF and replaced twice already.

I'm worried about the temperature.

Once, i tried to increase the FSB to 1600MHz and the cpu at default speed. it looked well and stable, but the cpu voltagewas around 1.4. i box says 1.35V Maximum.

_________________________

My Core temperatures seem very high.

When i don;t overclock the CPU temp on idle is 33 degrees celsius and the Core temperatures are as follows,

Core # 1 - 48 C
Core # 2 - 48 C
Core # 3 - 44 C
Core # 4 - 50 C

You see the huge difference between Core # 4 and 3! Very huge difference between the CPU and the Cores.

Is there any risk having the CPU volt 1.4?

stressfreesoul

It might shorten its life a bit. Over volting is probably the root cause of your high temps.

FreoHeaveho

1.4 volts is nothing to worry about. Reapply thermal paste.

tandav

I reapplied the thermal paste and now the Core # 4 temperature is equal to Core # 1 and 2, but Core # three is the lowest by at least 5-6 degrees celsius. CPU temperature is 33 degrees on idle @ 3.0 GHZ with full speed fan (stock fan). So, far no problem. i played couple of games like, NFS underground 2 and NFS Pro Steet and no error. Core temperature on idle is 46 now. CPU temp on full load reaches not more than 47 and remains at 45 unchaged after running Prime95 for more than 10 minutes.

Vcore keeps changing. normally it is 1.336 V and i even saw it go up to 1.4 V for just 2 seconds.

My mobo is Asus P5K SE/EPU. How can i keep the vcore at fixed volt?

Thanks!

tandav

I found stability at 7x400FSB, but on auto the vCore was 1.4V. On my Processor box, it says 1.35V maximum.

What the default CPU voltage of Q6600 G0?

stressfreesoul

I wouldn't worry about 1.4v, you sorted the temp issues by the sound of it. Now you should test it at the 2.8Ghz you have achieved with Two instances of Prime95, this should cover all cores and test the stability of your overclock. If it fails, you need to look at why...

FreoHeaveho

Again, that CPU will go to 3.6GHz no worries.

tandav

Specs;

Stock HSF
Asus P5K SE/EPU
Super Talent 2x2GB=4GB 800 MHZ
nVidia En8500GT 512MB

So, can i still do 3.6GHz? Memory Dumping (Blue Screen Appeared) when I tried Prime95 @ 3.2GHZ. I only increased the FSB and set everything else to Auto, except the PCI-E and CPU Spread Spectrum.

:)

PCI-E and CPU Spread Spectrum were disabled.
