Help!? 92c seems high

p5b-e with conroe 6400 cpu, neither ever overclocked (i just haven't had the time) set up in October of '06. This runs as my home media server. Thermaltake 700W power supply, three wd 500re drives raid-5 for storage, 1 barracuda as boot drive.

Ok - sitting idle with minimal cpu utilization it has 5 times now in the last two weeks shot up to over 90c. This is measured by both speedfan and the asus utility. There has twice been an odd vcore jump, which returned to normal, a half hour before the temperature "episode"

The MB stays at 45c or less
The computer seems to keep functioning fine, though I do shut it down, no sign of thermal throttling
There is no sign of harm after restart. I encode and play full hidef movies in h.264 on this system, there has been no noticeable performance degradation.

At first i'd think cpu or mb, but I don't have the spare parts around and hate to tear my whole HT rack apart without a clear mission in mind - any advice? Everything was purchased from newegg.

Try FORCING a Vcore of 1.35 in the BIOS rather than letting it sit around "Auto"
 
I will give that a try when i am home from work tonigth - is this a common problem with this board or with the conroes? I haven't seen anything about it. Given that the vcore spike was separated in time from the thermal condition I wasn't certain that was the source of the problem.
 
When set on AUTO, the motherboard will ramp up voltage with more cpu speed, which is not always a good thing. On very high overclocks, voltage will dip into dangerous areas, causing heat thus those warnings.

Setting to a specific number will make you sure it stay constant no matter what cpu speed. This will also help keep the heat in check.
 
Use CoreTemp or SpeedFan v.4.32 to see what your real CPU core temperature is. There are some issues with some other programs.

CoreTemp can create a log file if you tell it to so even if you're away from your computer you can go back through the log and see the temperatures.

1.325 volts is the Intel default for most E6300 / E6400 chips.

In my testing the C2D starts to thermal throttle at approximately 80C which keeps it from ever reaching its rated maximum of 85C so it's not likely that you were ever reaching 92C.
 
yea the auto setting has been known to throw as much as 1.65 volts :eek: yea you heard me, ive seen a screen shot on another forum from someone overclocking, booting windows, opening CPUz and TAT, cpuz says 1.58vCore (AFTER vdroop) and TAT idles around 100c. they got the screenshot off seconds before he pulled the plug. which is longer then i would have let it go. if your doing ANY overclocking its better to be safe then sorry and manualy set vCore.
 
At least these things are pretty robust.

My Girlfriend turned my desktop on 2 nights ago...

Yeah... There was no HS attached ;).

Booted up like a champ when I refilled my water system though.
 
I once had a theory that my Asus motherboard was not reporting the proper temperature for my Pentium 3. I decided the smartest :rolleyes: thing to do would be to pull off the heatsink and fan and start it up and head into the bios.

I used the most accurate temperature probe I had available, my thumb, and placed it directly on the core of the CPU. YEOW!!!!!

I think I lost a layer of skin that day. By the time I looked up at my screen I saw 100C and pulled the plug real fast. Surprisingly, it's still running fine today for my neice. It was idiots like me who encouraged Intel to build thermal throttling into their processors.

Now people just need to turn that feature on in the bios.

My most recent success story was my x1950XT that showed over 100C while running ATI tool with lots of volts and the stock cooler. I think I saw 110C before it crashed. Some things never change. :)

Hahaha... After about 2 days of testing my current Sempron (bought on the FS forum) I noticed the HSF would never get warm, and the system (of course) wouldn't post.

Fast forward 2 days of testing with different components, and calls to Asus tech support :)o)... I did the thumb test. That proved the chip was dead as it doesn't even get warm to the touch.

Sigh.
 
I wouldnt be worried yet, I doubt the temp was that high due to throttling. Core temp is the best way to go. I have a biostar board that always reports my opteron at 127C in the biostar monitoring software, speedfan, and Everest. Core temp is the only program that reports a believable temperture.
 
This is all helpful, I will try those two utilities and report back. I thought 2v of vcore seemed unlikely, even for a moment, but my computer would never lie to me :rolleyes:

While I'm here and sort of on the subject - I've never tried water cooling but given that this is a theatre systems (i'm hosting over a TB of hidef movies and music), I'm interested - My question is, why does it seem there is no external water system that can hook up to the cpu, vid card, and hard drive cage all at once? It seems like all these bulky external systems are good for just one component. I would think you could have one radiator with three or four coolent sections so that one device and set of pumps could serve every crucial component. I just don't see the use of water cooling if you are going to have to leave some of your fans in place.
 
my old Exos (first revision) was able to power my p4 northwood 3.2 to 3.6 while cooling my northbridge, 4 hard drives, video card and a custom 226w peltier powered case air conditioner i riged up. the Exos2's should be able to do everything you need as long as your not overclocking hardcore.

Basically you are correct.

We can get much higher overclocks with water and fan noise is reduced significantly from screaming air cooled solutions at extream OCs but there is still plenty of noise. It depends on your design goals. If you start out to do WC with low noise in mind and are not trying to get the absolute maximum overclock out of your system, it can be almost silent, but you have to have fans to move air, WC just lets you use very low speed ones.

You can usually graft in a gpu block into the cooling loop of most external systems without any big issue.
