Am I ok at 61c?

That's higher than I'd feel comfortable at, but is it a B3 or G0 processor?

I have been running my QX6700 at 65C for months on all four cores, and it has been stable. Much hotter and it goes unstable.

I plan to change the stock air cooling for something better, and will then push the clock back until I reach anout 60C.

It's good to be back amongst friends and colleagues

Am I ok at 61c?

Well within spec. I ran mine at about that for 4 - 6 weeks without any problems but then changed out the Ninja cooler for a Thermalright Ultra-120 Extreme (lapped the processor and the base of the heatsink before I put them together as well) and am now running below 50C, since the AS5 has bedded in. And that is with an increased clock rate. I prefer the extra headroom.

Intel spec for the Q6600 is 62C. Above that your milage may vary;)

Be aware that temps can change by 2 or 3 C depending on the WU being processed.
So that 61c may jump to 64C or more in the middle of the night while you are catching a few Zzzzzz.
Good luck.

When we finally figure it all out, all the rules will change and we can start all over again.

It's a GO Ive' been bouncing all around , just got a temp prog I count on Core Temp no errors up to 3.4 @ 63c, but I have stock cooling, and got scaird?
Running at 3.0 and 60c now. Today ordered a hsf and silver 5 I'll be bolder then,, Thanks for your temps,

Gee and i was worried about 45C!

I am running thermaltake big thphoon for CPU cooling and a few extra fans for pumping cool air into the case and Hot air out. I am currently @ 3456Mhz with cpu temp at 52C and MB or system at 36C. MB is from ASUS P5K with suggested max system/MB temp of 45C
The CPU is Core 2 Quatro G0. Memory is Corsair Twinx 8500 at 5,5,5,15.
voltage for the memory is in auto and for the CPU it's at 1.45. I have been running without glitch for over 24 hours now. As the optimist said when passing the 5th floor of the Empire State Building after falling from the observation deck at the top, "So far so good".:)

The specs for the G0 are better, 71. In any case, better cooling for the CPU is a good thing, and like Pilot mentioned, there are other temps that you should also be careful of. You're more likely to damage the memory or motherboard from too much heat than the CPU if you're running close to the limits.

What are you using to monitor system temps? I was dissapointed with speedfan and motherboard monitor,they seem to read about 10c low.Tat and Core Temp feel good but neither have system temps.And now I don't trust speedfan.

I've found good agreement between Coretemp and Speedfan (incremented by 15C on the core temperatures). I don't take too much notice of the System temp (=Southbridge on my Asus P5B D/L WiFi MoBo) but the difference between the "CPU" reading and the "Core" readings in Speedfan (including that offset) is 7 - 8C which is as expected.

The one reading I would like that isn't available on this MoBo is a Northbridge sensor as that can get very hot to the touch when overclocking.

Here's whhat I have. What can I beleive?

In the advanced tab for Speedfan options, set the offset for each core of the CPU to 15, Speedfan by default is set for the 85 tjunctions, but the Q6600 has a 100 tjunction, so once you do that, they should be roughly the same, but possibly slightly different due to polling intervals.

While the difference between the two applications is the infamous 15C ambiguity in divining Intel's intentions and mistakes, there is an additional probable error in random miscorrelation of the sensors.

If you really want to know, you'll calibrate your own sensors. You can find some suggested methods online.

My personal method was to remove the panelling from my CPU case. Turned it off for a half hour while running a large box fan directly into its side. Then, panels still off and fan still running, I booted, and made sure no optional aps were running and that all my PC fans were running at max (especially the CPU Heat Sink Fan).

I believed the sensor temps a couple of minutes after the (power-consuming) boot should stabilize to very close to the ambient air temperature in the room, and used on SpeedFan 4.32 the Readings|Configure|Advanced|Chip:Intel CORE

page to set offsets.

For my sample of the Q6600 B3, this procedure caused me to set these offsets to:
Temperature 1 Offset: 0
Temperature 2 Offset: 4
Temperature 3 Offset: 4
Temperature 4 Offset: 3

While the 15C matter gets a lot of attention, fewer folks seem to recognize that there is several degrees C of random scatter for specific sensors on samples of the same stepping.

Hi,

I once again recommend that you read this fine guide to temp-measuring on Quads and Duo's.

That is the fan I am thinking about getting for my new Q6600 machine when I build it. Would you recommend it?

And no good credit hound!

I certainly would reccomend the 120 Extreme. I have one machine with one of these, not lapped, though. It's running about 12-15 degrees cooler than the machine next to it that has a Zalman 9700 in it. Same boxes (P180Bs), different memory, the 120 extreme has faster memory, but they have the same amounts. Very similar components, though the 120 extreme one is currently using integrated video, the other is using an x1300 Pro card. I did have an x1300 Pro in the 120 extreme one for a while for testing, it only added about 1 degree overall, probably just because it messed with the airflow some. The 120 extreme box is also OC'd slightly higher than the other one (3120 vs. 3060).

-Dave

[edit] Oh, I hung an FM121 fan on the 120 exterme, FYI...

Thanks for the reply, Yep I will give it a try. I have never lapped a CPU or fan...Too Lazy I guess.

temp on my quad not OC and original fan from intel....
and a lan conection for duration....
stability 100%



and E6600 not OC and original fan

Brbe, if that were my Q6600 machine, I'd be looking for something wrong... that's way hot for not even OC'd, maybe the heatsink isn't seated properly?
