I searched around and I keep reading different opinions depending on what each has or believes is the best according to what cooling solution says is the best..

My question is very simple.

What is the maximum temp that the Intel C2Q Q9550 can operate without harm to it or the socket? Not what the best would be or in general etc.

Thanks in advance if anyone knows.

well i ran the Q9550 at 70C idle at one time and while i do not recommend that at all for long term use, it was stable with a mild OC (3.0GHz).

this was in a liquid cooling system where the fans were turned off so the load temps didnt get higher than 79C either however...

As long as the core temps (not "CPU" temp) are below the Tj max value it's fine. For Q9550 it is 100°C, the CPU should start throttling when the cores get near that limit and eventually it shuts down itself when the temps get dangerous.

Judas

whle they state that 95-105*C is the maximum before sevear damage takes affect

personally i don't like seeing a cpu over 50*C myself...

i would be concerned about 60*C under load

My cpu runs idle in low 30s, loads in mid 50s when doing any normal work, and loads in low 70s for stress testing/heat production tests. I think for most chips the tj max value is between 95 and 105 (as stated before - the 980X's is 101C), but again - any time I hit over 80 is time to turn it down a notch, imo.

BlueMak

Ah good, thank you guys. I was beginning to think I was in the need of an urgent solution. As it is now it can get up to mid to high 70s under load. while around low 50s during normal desktop work.

i think my current i7 930 stock runs idle about 27C and load it's around the 40-45C...

my gpu's on the other hand is a different story.. course now that we are into the fridged temperatures... i'm sure i'll be using my computer to heat my room

The vast, vast majority of PCs out there break 60 degrees under load. While lower is always better, it's perfectly acceptable. I wouldn't raise eye brows until 90 or so, presuming that you're testing worst case scenario temps (and if not, why not?).

majority of the machines i've seen that idle at 40-60C are prebuilt machines with terrible heatsinks or cooling solutions and are in cramped cases...

all bad... heat is terrible.. the hotter things run even thought within spec.. the sooner they will fail..

All of my machines i've built generally under load never break 50C...

Personal preference.. but i do not general accept the "accepted norm".... 60C is to high... i don't care what it is... shouldn't be running that high... i hate the idea that my ATI gpus break the 70C mark under load.... but i've done everything i can within reason to keep it no higher then 80C

GPUs and CPUs run completely differently in terms of temps, though - so you can't really complain.

I had an 8800GTX which idled at 65C and loaded at 95C, and worked fine for over three years like that...it was just a hot card. To me, a 70C load on a graphics card seems like a blessing.

CPUs differ in temps, and I'm surprised you manage to get such low load temps. Even the reviews here on HH show similar full load temps (65-85C) (go look at the 980X review). I get 100% load temps at 60C, but not when stress testing (76C...ouch).

Just out of curiosity, Judas, running a prime95 test with large FFTs for a couple hours straight - what temps do you hit across your cores? And what's your cooling solution?

blibbax

While it is true that the hotter things run the sooner they fail, a CPU which never exceeds, say, 70 degrees (just to use an example that is more than 60) will most likely last until it is far beyond obselete, presuming of course that all other variables are within sensible parameters.

CPUs and GPUs actually have remarkable similar heat tolerances, but as synthesis saysm the vast majority of GPUs run fine for years at temps of well over 80 degrees. The only worry when you see a component running that hot is that there may be a situation in which it runs hotter.

well lets take the Phenom II 940 i had gotten... while i had a Coolermaster V10 on it... lidle temps while overclocked averaged 24-27*C and and barely would break 40C

When i tried to gain more overclock... reguardless of the voltage and other settings i tried i could not get it to be stable beyond even when pushign the temps up to 60C with excessive voltages... was always best with a marginal overclock and stock.. which remained in the below 50C mark under the most extreme conditions..

using a slightly smaller heatsink resulted in really no change in temps though.. but obviously less ability to cool compared to the v10 at extreme conditions...

You're saying it was 40C under a stress test (prime95 FFT or comparable)? If so, AMD should be further ahead in the CPU war than they are.

And yeah - the V series coolers really are wonderful.

Judas

actually



just so you know

That's running under idle - but regardless, this isn't the place to have a debate over core temps (:

I do think BlueMak got his answer

Judas

i was trying to track down the orginal sub 35C stress load temps... they are somewhere on this huge forum lol

Judas

i stated the facts stated about the temps that are rated for the CPU's in general... and then stated an opinion and what i've seen about cpu's and their idle/loads...

i don't think i ventured much at all outside the very threads subject at all

You just love to argue, don't you? (:

BlueMak, out of curiosity, what are your idle/load/stress load temps?

BlueMak

Yeah, you pretty much told me what I asked not to be told.
I don't mind, we all do it in forums, but try to read the actual post the next time.

So far they are very high, but nothing dangerously high.

idle (that is windows desktop with an open browser full of tabs) about 59C, load at mid 70s and "stress" (lots of gaming while having a couple of other programs running, max of 81C.
This with going to the BIOS and having the fan settings for the case and the CPU fan at the quiet mode. At the Turbo mode it drops between 5-10 degrees depending, but at Turbo mode the fan speed keeps changing and the slight difference in sound it makes, pisses me off. (same for Standard setting)

I know part of the problem is my graphics card which is just too hot. Increasing the GPU fan to 80-100%, under load it reaches 100C and depending on the game, goes over it. I had to disable the Catalyst AI which effectively disabled the second part of it and with the fan at about 80% it reaches temps of a bit over 80C. So yes, it is pretty darn hot.

In case you are wondering, I used a full can of compressed air and cloth to clean both the case and the hardware inside. The temps dropped to the above level...
There is a 120MM near the HDDs (front), two 90mm fans on the side of the case (GPU height), and another 120mm in the rear.

Yes, I would get a new system if I could afford it, but I can't, so I am gathering money so hopefully by December I will be able to afford at least an 6870, but only if there is one without stock cooling.

Why not go for a 6850 or 460 - you'd be able to run anything on the market right now at max or near max for the most part, and it's much cheaper (you could SLI/XFire later, too!).

And yeah - the only card I remember ever getting that high would be my ancient 8800GTX.

And those temps are worrying but within the range of "not going to cause serious damage to your cpu"...for now. If you were going to do anything, I would recommend getting a new cpu cooler

BlueMak

I have a good CPU cooler, I earned it from a competition from eh, where else HH (DH then) but I dislike building a system (or in this case replacing a part) that I am trying to avoid using it for this, plus because I have a weird bad luck with handling CPUs, I want to avoid touching it lol. Don't worry though, when I find a job here* (5-10 years from now) I will be able to building a new system.

Regarding the GPU, I might get a 6850, but I am not going to get an Nvidia solution.
I am waiting for t his month (as I said earlier), plus with the release of more AMD cards in the next couple of weeks, I should be able to get something cheaper.

I smell an ATI fanboy Oh well.

The Sapphire 6850 looks shiny, imo...

BlueMak

Please don't call me a fanboy again. It is very inaccurate.

If I get a 6850 I will go for one which is cheaper or has a game bundle, unfortunately the Sapphire's don't for now.

Sorry, sarcasm and teasing, BlueMak (:

True, but they also have non-stock-cooling.

BlueMak

Eh, there is a 6870 with non stock cooling out now?

None show up on the Egg or TigerDirect yet. :/

iPlayer

The 4890s could get real hot too.

And why avoid nvidia altogether?
At least I experience less issues with nvidia drivers in general.

BlueMak

I keep reading about ATI sucks with their drivers and Nvidia sucks with the drivers every single year for the last at least 6 years. Having experienced both brands extensively, all of that is just hot air. Both have issues all the time. I don't buy it.

As for why avoid Nvidia, I refuse to buy them for the way they do business. Despicable.
