QX6700 Temps

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.

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.

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.

Both of you really, but mostly you . If you're getting 66°C stock, that's already over the thermal spec. I'd be a bit concerned if I were you, but I supposed it could be the software mis-reading the temps a bit?

Definitely time to start thinking seriously about water cooling . Certainly for o/c'ing anyway .

What are your ambient temps? What's the fan set-up in your case? Have you got a fan feeding the fan/s on your heat sink with cool air from outside the case, or do you rely on the front intake fan to feed the case and heat sink with air from outside the case?

Yeah ok thanks,yeah when i said getting 66°C stock,i ment the cpu was running at stock speeds but i was running all 4 cores at 100% to get the 66°C,at idle the cpu runs at about 40°C,yeah when i was getting those 80°C, it was a hot day outside around the 40 degrees,but even when it is a cooler day like around 30 degrees outside,the cpu still runs pretty hot,probley around the 75°C when its overclocked,so now i just leave it at defalt clock speed.

With the fan set up i think its faily desent,like the cooler master stacker 830 case both side panels are like mesh type grill that let air in,so i guess that would be a good thing,and when you take the right door off theres this swinging clear plastic door where you attach up to 4 extra 120mm fans,ive got 3 120mm fans in that door,and there pretty much aimed right at the cpu cooler (big typoon) you can sought of see the swinging door setup in this this pic
http://www.coolermaster.com/show_pic...bc777d1641.jpg but yeh anyway i think my air flow is ok.

I deffently agree on the water cooling though since i would like to be able to overclock this cpu and still have low temps,how much better is water cooling by the way,will it lower the temps 20 to 30 degrees better than the big typhoon air cooler,or is water cooling only a little bit better.

Depends on what you get really. Low-end water-cooling is only a little bit better than high-end air cooling (like the BT) so if you're going to go with water, you'd need to be looking at mid to high end to make the investment worthwhile.

There are some good water cooling kits available, but generally you can get better performance per dollar with a customer set up. If you're thinking seriously about getting water (which I think would be a good idea in your situation) post a thread in the water cooling section and ask the water cooling guys to put a "virtual" custom set-up together for you from Newegg etc within your budget. They know their stuff much better than I do and will be able to help you every step of the way .

Btw, I agree your case airflow is fine. That case looks like it has ample airflow.

Keep in mind when Intel specs a temperature or a voltage, that is so the CPU will last at least 5 years. I doubt most people on here keep a CPU 5 years, so running 5-10C hotter than the spec probably isn't that bad. It may last 3-6 years instead of 5-10. Long enough for me.

Quote:
Yeah thanks,yeah low end water would deffently be pointless so i would go high end for sure,i don't mind spending extra money because i plan on keeping this system for about 4 years and it would be nice to get a high end water cooling system to be able to overclock it to around 3.6 or 3.7ghz and still have around 60 degrees temps on full load.

By the way what is a "virtual" custom set,is that like a home made water cooling.
Yeah i have been having a few problems with this new system,my enermax galaxy power supply was faulty the other day and the replacement has just turned up today,so i have been fitting that all day,everytime i cranked a game up the internal buzzer inside the psu kept beeping constantly,so i had to get it replaced.

Soughting one problem out at a time,now i will sought this heat problem out,another problem is i seem to get this pausing effect when i go inside folders on the harddrive,like when i go into a folder i get the little hour glass up for a little over 1 second before it will go inside,i know its not a real big deal but these raptor harddrives never did that in the old pc i just took them out from,so something is causing it,not sure yet.

Hi ManDown,yeah 80c deffently didn't feel to safe thats why i am now running at default speeds which seem to stick at around 66c at full load,which is not to bad considering there is 2 cpu's on one chip,but now i have desided to go water cooling i am hoping water will allow me to go saftly at around 3.6ghz to 3.7ghz.

By the way how much thermal paste did you use when aplying it.

I guess my higher temps than you may have something to do with the fact that i live in a part of australia that is fairly hot most of the time,like most of summer the weather is around 30 degrees up to 48 degrees,and thats pretty normal weather here,like the other day when the cpu was at 80 degrees,it was a 40 degree day.

You know i am starting to think that water cooling might not even be enough for me because i was reading a review on the Swiftech H20-220 Apex Ultra Watercooling Kit http://www.overclockers.com.au/artic...?id=516509&P=5 which cost around $500 australian,and all it done was lower the dudes temps by 10 degrees.

I am looking at this system,have you heard of the Swiftech Thermoelectric Series Liquid Cooling Kit LGA775 http://www.pccasegear.com/prod4654.htm it's like a halfbreed of water and something els and they recon it gets the cpu down to 0 degrees and 0.5 on full load,i was reading the review here http://www.mvktech.net/content/view/1978/39/1/0/ and it looks like it installed similar to the vaporchills,in the way you have to spray all that stuff on the motherboard to stop the condensation.
