High temps when overclocking with core temp

[JD50]

I am getting extremely high temps using core temp, I'm at about 75c when running orthos, about 45c when idle. I don't get any errors in orthos, but the temps seem a little extreme. My specs are

ASUS P5k (normal, not deluxe)
C2D e4400
500w antec PSU
nividia 8800 gts 640 mb
4gb OCZ DDR2-800 (4x1Gb)
Vista home premium 64
Zalman cnps 7700

When I use speed fan my temps are about 15 degrees cooler, around 60c under full load. This is at 3ghz and the vcore is at 1.375.

Also, I've opened the case and felt the heatsink when its saying that its 75c, but it doesn't feel hot at all. Any ideas?

I think that Core temp is misreading the E4400 temps by 15C - I believe that I've read about it in some other threads, and it is a known issue.

Keep in mind - Max. "safe" temps are CPU 50C, Core 1/2 65C.

Yea, thats what I'm thinking, because Asus Probe and speedfan are both showing the same temps, CPU is at 50c and both cores are at 60c while running two instances of Orthos small FFTs with each one set to a different core. But, I thought that I had seen that speedfan has been off on its temps with version 4.32...

Download Coretemp 0.95 and check for your Tjunction temperature. If you see 100C, then you can safely push peak coretemp under TAT/S&M/Orthos to 80C. Coretemp reports the temperature at each core. This number is usually 15C higher then the average case temperature reported by Speedfan. Your numbers are very similar to my 4300 prior to removing/reseating/relapping my heat spreader (drop by 8C).

I keep getting an error when trying to run tat. It says "error enumerating on demand clock modulation support. terminating tool." anyone familiar with that problem?

I'll give it a shot, thanks. On a side note, I just downloaded everest and its showing roughly the same temps as speedfan and Asus probe, so I think I'm probably safe.

I can't get TAT working either, I don't get an error, it just doesn't start. I'm using Vista 64.

TAT and coretemp doesn't work with 64-bit Vista

 

[SerpentRoyal]

Coretemp 0.95 works with Vista Business 32-bit. Not sure about 64 version.

I'm using xp home. I don't really need TAT since I can use speedfan/coretemp/abit uguru/etc, but it's always nice to have SEVEN methods of determining temp instead of only six...

TAT doesn't work under Vista x64, however CoreTemp .95 works just fine.

As a side note, the entire situation with C2D temperatures starts pissing me off.

Hi all

I have a similar problem with temps - I am a little concerned that when I overclock my E4400 to as little as 2.4GHz the temps are getting up to 67/67 cores and 64 CPU. Normal idle temps are 40/40 and 37.

I have a Zalman CNPS7070Cu but it never really feels warm to the touch. Could it simply be bad contact between CPU and heatsink or are these kind of extreme temperatures to be expected?

See screenshot http://img504.imageshack.us/my.php?image=tempsmt4.png (ignore the "-50" reading in the system tray - this seems to be a glitch and it should read 63).

Cheers

I think Tjunction for E4400 is mostly 100C, if you use speedfan 4.32 you have to add +15 to the core0, core1 temperatures. The best way is to use coretemp 0.95 that shows your temp. flawlessly and accurately.
