QX6700 Temps

post #1 of 29
Thread Starter 
Hi

I have managed to find out that the QX6700 runs hotter than other CPUs and I have heard some running them @ 70c, but does anyone know what sort of temps you never want to see on TAT with a QX6700, have been told to add 10c on normal temps, so keep it below 65c max right? Sounds high to me, anyone got any further info?

Basically I have managed to get mine to 3.5ghz from 2.6, but its @ 70c when on 100% load in TAT - Is this bad or ok with this chip?

Intel made the thermal throttle start at 80C. No idea if this is to prevent catastrophic failures or ensure a decent lifespan on the chip....

I'm curious, does TAT see all 4 CPUs and allow you to exercise each one individually?

How are you testing load temps, you should be using ORTHOS, or Prime on all four cores to see how stable it is. Try and keep load temps below 70 if possible. GL

Max suggested load from intel for a stock system is ~65c as can be seen in the thermal specs attached.

TAT sees all 4 cores in the log, but only 2 temps are displayed. Othos temps go up to 57c, but it goes higher when TAT is "At 100% load".

Tub - Thanks alot for the table

Still not giving up, got an 850w PSU coming tomorrow which I hope will make things a little more stable. Determined to hit 3.66ghz!

yeh i just built my QX6700 system and i was resently asking the same question about my high temps on forums.overclockers.com.au and they pretty much told me that my high temps were ok,the QX6700 has 4 cores and runs really hot so i'd better get used off them i was told,so i just excepted the high temps,since even at high temps my system is really stable.

When i had my QX6700 overclocked to 3200mhz it was running at 80 degrees when i had that new version of prime95 running,that loaded all 4 cores,and even though i was told that 80 degrees is ok,it still doesn't seem right to me and i don't like those high temps,so now i run the QX6700 at default speeds of 2.66 and at full load with prime95 my temps are around 60 to 65 degrees which i am happy with i guess.

By the way i am using the big typoon vx to cool the cpu and i even added another 3 of these case fans to my stacker 830 Scythe S-FLEX 120mm Fan SFF21F http://www.pccasegear.com/prod3652.htm and i still get high temps when i overclock,so untill i go water cooling i am leaving it at default speeds.

heres a screenshot when i only had the QX6700 ocerclocked to 2938mhz and it was running at 80 degrees,also i notest the longer you leave that prime95 the higher your temps will go up,mine peaks at 80 though.
And in the other screenshot you can see the highest it got was 66 degrees when it was running at default 2.66 speeds

tell you the truth though i don't think these QX6700 cpu's really even need overclocking,because they are fast enough,when i use dvd shrink to shrink an 8gig dual layer stawars episode 3 dvd when it was overclocked at 3200mhz,it would shrink the whole dvd in 2 minutes and 30 seconds (2.30) but when i set the QX6700 to default speeds of 2.66,it would only take an extra 30 seconds anyway,2 minutes 59 seconds (2.59),so with all the extra heat from overclocking i don't think you really get enough gains.

I was also thinking about phase but i have read that it can be a real nightmare to install,so i have desided to go water,can you recomend the best water cooler to use,i don't mind spending a desent amount but i just want to get a good quality water cooling kit that will do the job,water cooling is new to me and i am not sure what kit to go for from this site http://www.pccasegear.com/category159_1.htm

By the way ManDown sorry for hijacking your thread,but i guess all my questions would interest you anyway.

Stock Thermal Spec is 65°C according to Intel.

This is usually measured at the IHS. Thermal Throttling could well be higher, but I was always under the impression that the Thermal Specification was the maximum rated operating temperature for an Intel CPU. My E6600 is 60.1°C and most people would advise to stay below that. Based on that, I'd say you'd be well advised to keep the chip below 65°C if possible.

Perhaps your heat sink isn't seated properly? Are you using AS5?

I am not sure if you were speaking to me or ManDown,but yeah for me i used AS5 and i must of reseated the heat sinc 15 times,i tried all different amounts and in the end i just used one strip down the center of the cpu and then put the heat sinc on and gave it a twist to rub the AS5 in,i got that of some site which they said was the best way to apply the AS5,allthough pretty much all amounts i tried all seemed to give similar temps.
