Temp Question about QX6850

[Csst]

I just got my RIG up and running here our my spec. Its at stock right now 3.0 and I'm running SLI with (2) 8800 Ultras and also using water cooling (swift tech) now when i run everest its saying my temps ate idle at about 56 to 57 under load it shots up to about 62 to 63 this seems VERY high to me. Is this normal? or is there something wrong here?

also just wanted to add this morning i turn my pc on for about 5 mins before i left for work and the cpu core temp was reading about 27 to 28 or so. you think this is because it has not been on long. lasnightemps to me were pretty scary the room temp last night was about 80.whashould i do?

50-60F or C? Farenheit would mean that you have extraordinary temps, Celcius means that it could be the 2 8800GTXs raising temps. Also, that's not really a big difference between load and idle. Are you sure Everest is reading right?

If you don't plan on overclocking the QX6850 much higher then you are likely fine with these temps.

They are "high" in the sense that having temps this high will mean clocking your system even higher will be double-trouble.

And I agree with BlueAcolyte that your SLI setup is the likely cause...total heat load on your system has got to be pretty high.

so you really think that my 8800ultras that im running is the problem so you think there a way to bring the temps down. so you think that my temps are low when i first boot up my pc but soon as the 8800 warm up is whats casusing the problem?

Its not that I think this (i.e. its not that I am 100% positive) but I am merely throwing out suggestion of likely culprits.

The way to identify the true cuplrit from a list of suspects is to start partitioning your problem.

To determine if the 8800's are the culprit simply remove one of them from your computer entirely (pull it from the mobo, seal the case back up and test).

If your CPU temps do not appreciably decrease then you can conclude the SLI setup is not to blame.

Start looking for additional culprits...such as ambient temps inside your case...maybe your fan setup for case exhaust is sub-optimal...remove the case sides and setup a box fan to blow air into the side of your case just for doing some tests...then see if your CPU temp remains sky-high.

Etcetara, etcetara...

I am running 2x 8800GT's in SLI and yes, the heat from those can dramatically increase the temp of the processor. If you look at the case, the airflow comes in the front, onto the 8800's, then the heated air flows up to the processor and that heat is what used to cool the processor before it exit's out the back of the case. Really, consider increasing the airflow through the case.

the case im using is the cos 1000.. so even witthe water cooling the temps can get this high..now please correct me if im wrong but i thought the max temp for the qx6850 is 70. the water is only doing the cpu and not the vid. cards.will these temps be safe for the cpu?

 

[sutahz]

You didn't answer Blue's question if the temps your reporting to us are in F or C. But I'm going to venture its in C (as every program I've seen reports in C by default, you have to specify F in the options).
Since your Ultra's are not in the loop w/ the cpu, i'd say 70C is an alarming cpu temp.
Whats your Vcore/Vcpu?
@GhostChild, he has watercooling, airflow thru his case will not help his cpu temp.

 

[Csst]

yea the temp are in C.and the temps i was gettin was around 57 to 58 idle. but this morning it was about 23 to 25 or so but i only had the pc on for about 5 mins top becuase i was leaving for work.i just thought it was odd the difference it was. the vcore 1.2. which is stock. i wanted to oc this thing but i dont think it will happen unless i get the temps down.

You need either a better cpu block, a larger radiator, a higher flow pump, or higher flow fans on your radiator. Also, are you sure you applied the TIM between the cpu block and the cpu correctly? Your temps are way too high, to be using watercooling, and only running @ 3.0 Ghz.

edit: Are you sure you have all of the air out of the system?

 

[Csst]

The way i did it was apply a small grain of rice size in the middle of CPU and than apply the block down on it??Also the fans that were installed in the case were already there.. The fans are not loud at all and i can barely hear them its very quiet.. Just to give you a example when i furst boot up the CPU was reading 34C and the GPU1 was reading 62 after 5 mins of just idling doing nothing at all the CPU went to 42C and my GPU to 79C. After 10 mins of idling CPU 49C and the GPU 81C now i try to install the Rivatuner and turn the fans on to 100%on the GPU after about 5 mins the change was GPU 78C and the CPU is 48C. Do you think i'm better of taking out the fans that are in there i have some fans from my old case that have speed controls on them to really get them working will that make any difference you think?

 

[Csst]

Ok here a quick update are these safe temps i seem to be idling around 41C on my CPU my room temp is 24C and my GPU is 68C and my MB is 41C i did notice that my radiator fans were not running at full speed so i changed both fans for that i also reapplied some Arctic silver 5 and redid my block.. When i put it under a stress test for 15 mins straight my CPU temp stayed around 51 to 52 are these temps ok? Keep in mind i am running SLI on a 8800 Ultra overclocked version also (not sure if these run any hotter). Also by getting these kinds of temps if i were to overlclock my CPU without touching my Vcore will the temps still go up? or will they pretty much stay the same?

Thanks

Those temps are much more like it. Now you know that even watercooled systems need case fans, huh? And yes, the higher you overclock, the higher your CPU temp will be. But, as long as you don't raise the vcore, they won't rise all that much, and will rise linearly. If you raise the overclock, and also raise the vcore, the temps will rise exponentially.

 

[Csst]

So do you think its safe to OC it a little without raises up the Vcore or you think i should just stick with stock speeds with the temps i have going?
