How hot is too hot? (Q6600)

I have read all sorts of things about the Q6600 Intel processor but one thing I am still unsure of is what is the point that I should say "This is too hot".
For instance, is 70c too hot?
Thanks for the help fellas.

i think thats a little bit too hot...but then again, it is 4 cores. i would say 50-60C, but i know nothing about cooling quad cores.

Thanks for the reply.
I am running TAT, and at stock speeds the temps are teetering between 69-70c...

I noticed that TAT is only testing 2 of my 4 cores and it is saying I have a Pentium M, is there a fix for this, is there a better tool that does the same thing that TAT does?

Thanks fellas

There's been some argument or whatnot about Intel's TAT program. It's been debated that its not made for use on C2D and C2Qs. So, with that in mind, that MAY explain why it only tests two of your four cores. You should try Coretemp (google it = P).

And for cooling your Q6600, have you checked your case's airflow? (Cabling, Fans, and such)

Can you give me the situation that you are getting those temperatures (all four cores pinned under two instances of orthos running or at idle). I would also agree with cmdrdredd and get the reading from coretemp or Everest which seems to have the same temps as coretemp for discussion. The rest of the products out there are usually about off by about 10-15C.

In my view too hot is above Intel thermal spec of 71*C for G0. I feel comfortable running at 67*C load. By the time the processor dies, it'll long be replaced. The lower the better of course, but I'd say 60*C would be definitely safe.

but does the 71C refer to coretemp numbers or the average CPU temp that motherboards reports. That could easily be $15-20 difference.

OK, so I am using coretemp to check the temps, I put another fan in my case, I only had 1 120mm fan in the back of the case but now I have the 120mm and an 80mm fan in the side window above the processor, the temps are down by ~10 degrees.
right now I have the processor running at 311x9 = 2800MHz and I dont think I have gone higher than ~60-65 under load, I will try Prime or something and get back to you guys.

Thanks for the replies.

**EDIT**
OK so I ran orthos for 11 minutes, at 2.8 and the highest the temps got were 69c but that core settled in at 68c, the other three cores were ~ 1-3 degrees cooler.

I'd argue that a per-core temp of 70c(with some fluctuation) is fine. It is a bit hotter than what "the rules" are for a C2D, but Intel feels confident enough to put the throttle temperature for these things at 100c, so ~30c below it should be safe. "The rules" were written for processors with an 85c cap anyhow.

I would say anything above 60 is hot...even if its physically okay to run your cpu at 70...you gotta have that peace of mind. I would never run my cpu on the edge like that...you never know what can tip it over to like 75 or even 80...maybe a humid day? One of your case fans suddenly dies? Too much dirt? You never know.

We're talking about a stress test program like Orthos or S&M loading all cores for a short period of time. 75C under Orthos would translate to about 55 to 50C when gaming or running any CPU intensive application.

humidity affects us, not temperatures. I cant believe people still dont know that.

I use CoreTemp because motherboard isn't able to report internal temperature of the cpu. It's the internal cpu temperature that is dangerous for the transistors and other metals which comprise the cpu die.

While humidity doesn't affect temperature directly...it affects the air....thus affecting your temperature. I can't believe you don't even know what humidity is. What you hear on the weather channel is heat index (what you feel)...not humidity. Learn your facts before you try to correct someone.

What setting should I have Orthos on, the 11 min run I did last night was set only to stress the CPU, I re-ran it to stress the Ram and CPU and the temps are maxing out at almost 10 degrees cooler.
Sounds good to me, hows about you guys?

umm, actually both temperature and humidity have very little effect on the specific heat capacity of air. but just for spite to prove you wrong, as humidity increases the heat capacity increases as well, which would make humid air a better heat medium than dry air.

why dont you learn your facts before you try to correct me. nice try though lmao.

LOL...actually you just proved that I'm right. Since most of use use air to cool the heatsink, of course the content of air is important. It's obvious. Yes, I was wrong on the humid air, but you're wrong on the whole idea of humidity itself, which is ironic because you were trying to correct me.

k, the only reason I said that was to prove you wrong. the heat capacity of air doubles from 0% humidity to 100% humidity, but a normal situation would be 20% humidity (normal day) vs. 60% humidity (bad day). that will make a tiny difference, and also a tiny difference in temperatures, perhaps much less than any sensor inside a pc is able to detect.

So just to smite you back harder. I'm gonna quote you again "as humidity increases, the heat capacity increases as well" So humidity does affect your cpu temperature after all. If you only sat there for 2 more minutes you could make the connection instead of rushing to correct me. People use air to cool computer computers, so it makes sense that that content of the air matters. The same goes for water cooling. The content of the liquid matters (density...etc).

That's nothing more than your opinion. The fact of the matter is that humidity will affect your cpu temperature. Just don't rush to correct people next time in that tone, especially when you're wrong.

no it wont affect the temperature. you seem to be completely denying the evidence.

the heat capacity of air will not change substantially with varying humidity. if you go into the desert with 30c temperature and 0% humidity, your cpu might run a bit hotter than what it would run in a 30c tropical forest with 100% humidity. this is not a real situation, nor would your computer function properly with 100% humidity.

so stop singing, pull your fingers out of ears and just accept that you were wrong when you assumed a humid day would cause higher cpu temperatures. you could have just corrected yourself and said "I meant on a hot day" and you would have look a lot smarter.

LOL...omg. Dude why are you still arguing. You contradict yourself so much it's ridiculous. First you said heat capacity increases with humidity: "the heat capacity of air doubles from 0% humidity to 100% humidity." Thats 1:1 ratio dude; thats significant.
Now you are saying it will not change substantially with varying humidity. LOL...what are you trying to pull? The whole point is humidity will ultimately affect your cpu temperature because your cpu is air cooled.
I'm going to quote you again....these are your words...NOT MINE. PLEASE READ YOUR OWN WORDS...for god sakes "that will make a tiny difference, and also a tiny difference in temperatures, perhaps much less than any sensor inside a pc is able to detect." OMG...what does that mean? HUMIDITY AFFECTS THE HEAT CARRYING CAPACITY OF AIR, MAKING IT LESS/MORE EFFICIENT THUS DECREASING/INCREASING CPU TEMPERATURE. END OF DISCUSSION. The degree of change is not up to you to dictate. I think you should stop it and give up. I proved I was right. You proved me right. What else is left?

You: "humidity affects us, not temperatures. I cant believe people still dont know that."

Me: Ummm...i think thats heat index dude.

You: "as humidity increases the heat capacity increases as well"

Me: I'll give you that.

You: "that will make a tiny difference, and also a tiny difference in temperatures"

Me: LOL? I thought it only affects "us."

You: "the heat capacity of air will not change substantially with varying humidity"

Me: What? That just totally contradicts what you said earlier. LMAO
