Intel Core 2 Duo e6850 Temps - High?
  1 / 4    
I built my first ever computer rig last week with an e6850 @ 3.0 GHz, 8800 GTX card, Corsair Ballistix RAM 2GB, Antec 182 case (lots of fans), and eVGA 680i mobo. NOTHING IS OVERCLOCKED.

When I first booted the PC up, and used nVmonitor, the mobo temps were 33C, GPU 59C, and processor low-mid 50sC idle. I thought this was high for the processor after reading posts and Speedfan showing the "burning" image for the temp. Cores were about 10C cooler than processor. Under load, the processor went to low 60s.

I opened the case and reset the Intel fan and heatsink. Booted up and the temp was in the mid40s working up to low 50s. Ever since, it's been high 40s to low 50s fluctuation. I even tried to reseat the stock heatsink a 3rd time, and I think I'm doing it right as it's completely flush against the processor and mobo and cant get pushed down more. Same result.

Then I bought the Thermaltake 120 Extreme with AS5 (1200 RPM fan installed on heatsink). Installed it last night, and booted up. Idle temp started at 30C and went and stayed in mid 30s. Cores were again 10C cooler than processor. I didn't try it under load yet. I think cables are managed and bundled pretty well in the case for optimal airflow to the component area. I have installed a fan in the middle area (replacement for mid HDD cage) to blow on high over components.

This processor being the quickest of the std. core 2 duos, is this the normal temp range, stock?

well nvmonitor and speed fan doesnt read core 2 temps right, and only read the Tcase temps and not the Tjunction temps, try and DL CoreTemp 0.94.5 as this program reads Tjunction temps which are the bests temps to follow.

abt the stock intel fan u should of been getting around 30s-40s idle and 45s-50s load so maybe u didnt sit the stock fan propaly, anyways u got your tmps fixed right with the TR 120 Ultra Extreme right?

I asked the Q because most people have posted temps of C2Ds of the lower clock speeds. I was thinking maybe because of the 3ghz speed, the temps would normally be a little higher.

Yea it seems the thermaright did a good job and hopefully once the the AS5 sets in it'll drop a few degrees more, but I expected more of a drop like into the high 20s since 30s is what the "stock" fan and hs are supposed to be.

Stock HSF sucks period. you shouldn't be surprised of the high temps with it. Good choice with the new HSF and thermal paste, it will be good to OC with. I hear it's about a 200hour break in period for AS5, so you might see a little more drop in temps.

After doing some more research, I see on Intel's site the max thermal temp for the E6850 is 72C, while the other Dual Core Processors (minus the 6650 and Extremes) have a max thermal temp of 61C. Right now with my newly installed Thermaltake 120 Extreme, I get an average idle temp of 35C, which is down 13-18C from the stock cooler I had on it before.

I guess this processor, like the extremes, run hotter than most dual core processors made by Intel.

If anyone else has the E6850 or E6650 advise your temps.

They do run hotter since they come stock with a 1333FSB.

There is two thermal temps for the Core Duo, the thermal diode temp (Tcase) and the digital core temps (Tjunction).

The Tcase temp is taken from the centre of the cpu IHS while the Tjunction temps are digital temps measured from within each core. There is a lot of problems out there with many motherboards reading the Tcase temperature incorrectly but still reading the Tjunction temps correctly.

The screenshot below shows everest running and what each temperature is (Tcase and Tjuntion) for my quad Q6600.

The Q6600 B3 stepping like mines has a thermal Tcase rating of 62C and a Tjunction rating of 100C. These thermal max specification differ in different models of the Core Duo. For example the new G0 stepping of the Q6600 now has a max Tcase of 72C with a Tjunction max of 100C.

Are those temps on load Deeko? They look good if they are!

No hehe thats idle temps. Load temps for the Tcase (CPU in everest) are between 41-48C when encoding or playing games depending on how intensive they are and the length of time. The Tjuntion (Cores #1-#4 in everest) temps for the same tasks vary between 65C-78C. Quads do run a bit hotter but Im far away from reaching the max specs for Tcase and Tjunction. I ran my E6600 at 3.4ghz for a year with similar temps with no problems.

Ah, well if they can take it ok that's alright - is this with the stock heatsink, or 3rd party?

Cheers. That looks quite a beast! How loud is it - can it be kept fairly quiet?

Not a whisper from it, running 2x 120mm silent fans on it <1200rpm.

That's impressive, one thing i hate is noisy fans! Did you buy it direct from them, or find it more local?
