QX9650 temperature issue

warhammer · May 7, 2008

Hi having temperature issue with QX9650 I noticed that 2 of my cores run hot 0,1 54C and 2,3 33C at ideal CPU temp 35C. Refer to screen shot idle and load.

Have also tried lower volts still temps are high as you can see it hits the 65C.

Have also checked the plumbing in and out are working fine water block is sitting properly even removed it and there was a nice even spread of grease (AS).

System specs are
CPU QX9650 at 3.6GHz 450x8 1.28V
BX80569QX9650 SLAN3 L740B305 pack date 03/06/08

XFX790i P04 bios
Corsair ram DDR3 1600 at 1.8V
Water cooled D-Tek FuZion water block 240 dual fan radiator Laing D5 pump.

Have emailed and there response is.

Thank you for contacting Intel(R) Customer Support.

I understand that you are concerned about the operating temperature of the Intel(R) Core(TM) 2 Extreme processor QX9650.

The maximum operating temperature of the Intel(R) Core(TM) 2 Extreme processor QX9650 is 64.5 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.

To verify the thermal information for this processor please visit the following website:
http://processorfinder.intel.com/Details.aspx?sSpec=SLAN3

There is always going to be a 5-to-10-degree difference between cores because there is a main core, which is going to have the constant load of the system (even when this is at idle conditions) and a secondary core that the motherboard and the operating system would determine when to function.

Furthermore, this type of situation is usually related to the incorrect recognition of the microcode of the processor. The microcode of the processor is an electronic string that works as an identifier that the system BIOS and the motherboard itself use for communicating to the processor when it comes to data transference. If the microcode string is broken (this can happen because of static or grounding) then the system starts reporting wrong information like overheating or wrong specifications on the processor.

I would recommend updating the system BIOS to the latest revision available.

To reduce overheating you will need to use a thermally advantaged chassis. A Thermally Advantaged Chassis will help reduce overheating to a minimum. Please check the following website to identify a thermally advantaged chassis:
http://support.intel.com/support/processors/pentium4/sb/CS-008537.htm

Additional thermal information is available at the following web sites:
http://support.intel.com/support/processors/pentium4/sb/CS-007999.htm
http://support.intel.com/design/pentium4/guides/252161.htm

http://support.intel.com/support/processors/sb/CS-015912.htm
http://www.intel.com/cd/channel/res...top/proc_dsk_p4/technical_reference/99346.htm

Also, high CPU utilization is almost always caused by an application or program, in many cases a virus or spy ware; therefore, make sure that your antivirus is up to date since this could end up in an overheating issue.

I would also recommend running the Intel(R) Processor Identification Utility to properly identify your Intel(R) processor.

The Intel(R) Processor Identification Utility was developed by Intel(R) Corporation to enable consumers the ability to identify and, in some circumstances, determine if their Intel(R) processor is operating at the correct speed intended by Intel(R) Corporation. You can download this utility at:
http://www.intel.com/support/processors/tools/piu/

I recommend following the Intel(R) processor troubleshooting steps at the following website:
http://www.intel.com/support/processors/pentium4/sb/cs-008007.htm

If possible please test the Intel(R) processor in a known working and compatible motherboard, to see if it has the same behavior.

So if i was air cooled it would be 10 to 15 C hotter!>

I have responded back and awaiting a reply from INTEL.

[QUOTEHello Adolfo S,

Thanks for the info the problem is those 2 cores have hit 65C+ under 100% load subject to room temp and case. Today I stressed tested the CPU Core temps were 62C, 63C, 50C and 48C room temperature of 20C case temp of 22C. So that means 2 core are going to be 70C+ on a hot day room temperature of 24 or 25C. My old Q6600 on the same motherboard ran cooler 38C to 44C under load it concerns me that I paid a premium price for a CPU that I feel is of poor quality what happens when I use a multiplier of 10 or 11 it will run hotter?.

I will also point out my system is water cooled, if I was to place the air cooled heat sink on the CPU temps would be higher and would exceed the max temp of 64.5C.

Regards][/QUOTE]

lets see what intel has to say.

Any advice would be appreciated.

Snap!

I have the same thing. I use a Zalman 9700 to cool my CPU on a 780i EVGA motherboard.

My idle are around 56/56/42/35, on load its about 66/66/42/56. At stock.

If i over clock, i can reach the 70 mark on the first 2 cores. Intel have said the same thing to me, and i have had my heatsink tested. I'm thinking off dropping my CPU in another machine somewhere and see if it runs warm in that too. If it does it might be a faulty processor.

Let me know what happens with your CPU.

Wow, that seems hot at idle.
My QX6700 idles at ..
0 - 36
1 - 37
2 - 33
4 - 35

Air cooled with cooler in specs.
(That's with the BIOS throttling it back to 1.6GHz at idle)
I still haven't had a chance to put in my QX9650.

warlord2000ad · May 8, 2008

The QX9650 is 45nm so should run cooler. I can only guess there is a possible fault, as there are a few but not a great number of posts all experiencing the same things. i am tempted to get a thermaltake 120 extreme, the really big cpu cooler with a 120mm fan to see if it will lower them any more.

But for the most part, people don't run any fancy coolers, or even the same as me yet there temps are upto 20c lower!

twicksisted · May 8, 2008

have you tested using coretemp?
http://www.alcpu.com/CoreTemp/

I found that switching on PECI in the bios gave me a more accurate reading aswell as it got the reading off the internal sensors in the chip and not off the socket.

My Q6600 has temp differences between 0,1 & 2,3 but only by around 5-10 degrees

warlord2000ad · May 8, 2008

Ive tried Coretemp and CPUID Hardware Monitor, they both give the same results.

Real Temp gives the same temps but excatly 10c lower. So even my stuck temp sensor is at 32 not 42. :rolleyes:

Edit

Ive been told Real Temp is correct, so it really is 10c lower.

twicksisted · May 8, 2008

also, worth noting is that you are running it at 3.6ghz.... thats gonna make it warm

Im running my Q6600 @3ghz at the moment and im sitting at 42c, 39c, 34c, 34c idle
(Its 23c ambient temp in my computer room at the moment)

warlord2000ad · May 8, 2008

True but the temps are the same at 3Ghz

hat · May 8, 2008

45nm processors have a faulty core temp sensor btw...

warlord2000ad · May 8, 2008

That's true, its common issue on the C0 stepping of the QX9650 so i was told my one of my friends that works there. Should be corrected in the C1 revision of the CPU. Luckily i just got the one stuck.

QX9650 Cooling

Hi,I am running a qx9650 at 3.9 ghz which idles at around 33c and maxes out at around 60c with cpu burn-in v1.01 running in 4 windows.

It is cooled by an air cooler.

Here are my system specs.

It is where I got the idea to build my system from and the cooler with 1 attached fan really does work.

warlord2000ad · May 23, 2008

Do you have the Intel Thermal Control on in the bios, the one which reduces voltages, core speed, multiplier etc when the CPU is not in use.?

warhammer · May 23, 2008

Intel is replacing it.

I tried the lowering voltage stock setting removed CPU and tried it in an X38 motherboard with Intel heatsink same two cores at idle temp was 61C (core 0,1) and load hit 80C and I stopped the stress test

So yoru temps increased from 53 idle to 61idle, after trying stuff :S
