Core 2 Duo e6700 temps - what should they be?

donu · Post by **donu** » Sun Mar 04, 2007 10:12 am

TAT (Intel Thermal Analysis Tool) readings are:
53 at idle, 79 at 100% workload.

OK or too high? I can't find anything on the Intel web site that says what the temps should be.

Seems about double what they should be.

To help people out, answer these questions:

Is it Overclocked?
What cooler are you using?
What case are you using?
Graphics Card?
Case fans? (#, and what kind)

This'll help people diagnose your problem better.

Overclocked: No.
Cooler: Noctua NH-U9F with fan pushing air through the heat sink and pointing towards the back of the case.
Case: Antec P180
Graphics card: Gigabyte GeForce 7600GT (passively cooled Silent Pipe II)
Case fan: 1 Noctua NF-S12 blowing out back of case (next to the Noctua CPU cooler)

Update: I took the side panel off the case and the idle temp dropped to 45, full load temp is 70.

I know there are lots of things I can try to bring the temps down. But what temps should I try for?

This first time builder appreciate all your comments. SPCR is the greatest.

What are you using to measure temperature?

Assuming your cabling isn't a rats nest, I believe your heatsink is not properly mounted or possibly inadequate.

Temperatures measured with TAT (Intel Thermal Analysis Tool).

Cabling is clean. I can try and remount the CPU cooler, but what temperatures should I try for?

My E6600 with a Thermalright HR-01 and a 640rpm fan is registering low to mid 20's during normal web surfing in a 22C room.

Running Orthos blend, I peak at around 40C with the fan still spinning at 640rpm.

I think you'd hope for an idle temp of 30C or lower and a peak temp of 50C or lower.

UPDATE:
I removed the Low Noise Adaptor from the CPU cooler fan.
TAT temps are now 50 (from 53) at idle, 76 (from 79) at 100% workload.

Next steps:
- add an exhaust fan to the top case vent
- remount the CPU cooler.

Those temps are far too high. I suspect a problem with mounting of the HSF. What thermal paste did you use?

Thermal throttling is supposed to start around 80c.

With my Xeon 3070 (same as 6700), TAT reports only 50c with fans at 100% (I am using a Tuniq Tower with a Scythe S-Flex F 1500 rpm fan inside it). With fans at 70%, I still reach only 56c, and at 70% they fans are pretty quiet.

There's lots of detail on C2D temperatures at http://forumz.tomshardware.com/hardware ... 21745.html.

I used Arctic Alumina.

That's what I've been looking for. Thanks!

What motherboard are you using? Are you undervlting?

The best I've gotten with my E6600 on an Abit Ab9 Pro is about 30 idle -- 22c room as well. This is witha ninja in a p180 and also in an antec solo.

Are you talking CPU (aka Tcase) temperature or core (Tjunction)? And reported by which program?

My Xeon 3070 (E6700), with a Tuniq Tower and about 600rpm fans in the Tuniq and case exhaust, idles at about 24c Tcase (30c Tjunction) with an ambient temperature of 20c to 21c. That's only a 4c rise over ambient in Tcase which certainly seems good to me.

I have a P5B deluxe. Speedstep is enabled and fan controller is set to silent mode. Otherwise, BIOS is still at default settings.

I'm reading that temp with TAT. SpeedFan gives me the same core temps and a CPU temp that is 10C higher.

Update: I remounted my CPU cooler (Noctua NH-U9F).
TAT readings are now 43 at idle, 69 at 100% workload.
Original readings were 53 at idle, 79 at 100% workload.
A big (and welcome) improvement, but temps are still higher than I'd prefer. Perhaps I need a better CPU cooler.

On the bright side, you can be sure your CPU isnt throttling anymore. Since remounting made such a big difference, I would say that your problem is probably related to your mounting technique - most likely you are using too little or too much thermal paste. You only need a very thin layer of thermal paste!

I'd also suggest getting yourself a more up-to-date thermal paste if you can for that matter, ie Arctic Ceramique, or if you can find it, Shin-Etsu X23 (more or less widely-accepted as the best).

Case: P150
MB: P5B-E
CPU: E4300
CPU cooler: Ninja with fan pushing out the back (Artic silver used)
Case Fan: Fan is pushing out the back (antec tri-cool is on low i think)
Measured idle: 42C on one core, 44C on the other (using TAT)
Measured load: 65C on one core, 68C on the other (using TAT)

Those temps are exactly the same as what i get with my E4300 on a P5B-E, with a ninja. I do have the E4300 overclocked to 2.4Ghz though. I am reading the temps with TAT and when i do the built in load test the temp rises to about 65 on one core and 68 on the other.

From what i have read those temps are still high but i am really to lazy to take it apart again. I used the stock mounting push pins that came with the ninja and i don't think they are very good, so i am going to make my own mounting system when i get some free time. When i pull it off next time I will probably go the full monty by lapping everything and make my own mounting system, which should bring the temps down.

E6600 with a Thermalright Ultra 120, AS5, Scythe S-FLEX E, and two S-FLEX D's exhausting the rear/top on a P180B, overclocked to 3.2ghz by 400fsb/8 multiplier, stock voltage, my CPU is idling (right now) at 31 degrees. It goes up to 56ish under load with 2 Prime95's.

This is on an Asus P5B Deluxe.

I use MBM 5 to monitor temps with the core2duo plugin, which reports near identical temps to CoreDuoTemp in a much nicer and more convenient fashion.

e6600 + p5b Deluxe with the side off I get ~44C idle with q-fan set to silent (~900-1100 rpm). It ramps up fast to 1400-2000 (very audible) and 60C+ so I've decided I need to get something like the CNPS7000-ALCU I have in my old p4 (quiet even at 2000RPM)

EDIT: wow that sig is old

I can't imagine a CNPS7000 cooling any better than the stock heatsink.

I recommend getting the JMC 120mm PWM fan to replace the rear fan and then install an Ultra 120 or HR-01 in a duct with the JMC. One fan will cool your CPU and your whole case.

I the same CPU and motherboard with the HR-01 <click>. The JMC spins at 640rpm and I've never heard it speed up.

yeah, probably. i was guessing it would be cooler because I get those kinds of temps on an old p3.2 with said HS and that runs a lot hotter with its stock HS than my e6600. in any case, those temps actually seemed reasonable to me. it was the sound of the stock fan at load that got me
