Quick question for you....I got curious and decided to use the ASUS Probe software that came with my MB to see how hot my system was running. At idle the CPU was 50 C. When I ran a performance test on the CPU which I assumed would be a real good strain on it, it reached 71 C. Is that temperature something to be concerned about? I appreciate your help.
 
If it consistently runs at 71*C on a day-to-day basis, then yes, that's very bad. If it hits it once, then cuts down again, it's still bad, but not a '911 OMG'. For stress-testing...well, I'd freak out if my D 940 ever went over 50*C, but I'm at a stock 3.2 Ghz.
 
Yeah, I freaked out when I saw it spike to the 71 C during the most strenuous part of the test. It stays at 50 C idle and usually gets around 55-58 C during normal operation. Hope that isn't too dangerous!!
 
58C isn't too bad but 71 is getting toasty. If you find it's getting that hot regularly I would back down on your overclock a bit more or get a better heatsink.
 
but arent these processors meant to be able to handle like 80C on a regular basis? i think the temperature is fine.
 
Its quite hot, shouldn't do any damage, but you're running quite close to the border when it reaches 71c.

D-800's run a bit hotter than the 900's, but still, I'd be willing to bet you can see mid-40's at Idle with an 805 if you take your time and do it right.

50's though, is fine for D-800-series under normal use. Unless you like seeing lower temp numbers, I wouldn't worry about it too much until it hit 55-57+*C at Idle.

Can they 'handle it', yes. Are they suited to consistently run at such a high temp, no. To reference a previous analogy I made, my car's engine is *capable* of running at 6,000+ RPM, but 'would' I consistently run it in that range...absolutely not.
 
I ran Ad-Aware, AVG and Ccleaner scans simultaneously tonight while I surfed the net and my CPU temp got up to 60-62 C. Does that sound too bad in your opinion? I've been idle tonight around 49-51 C. I really don't play any games on this system so it rarely sees that much stress. I may leaver her be for now.

For running three moderate CPU-intensive tasks at once, that's pretty good for a Load Temp. Keep in mind that you're taking a normally 'warm' CPU to begin with and OC'ing it, so of course you'll see higher temps. An Idle of 49-51*C is fine for what you currently have. There are folks with C2Ds OC'ed to mid 3.x Ghz and see low-to-mid 40's with their temps, so you're on par with a warmer CPU to begin with.
 
I looked at my Zalman fan last night and noticed it had some pretty heavy dust build up in the inside of the fan blades in the center. My project this weekend will be to clean the Zalman and apply some Arctic Silver 5. When I built this PC, we used the Zalman thermal compound that came with fan. I'm hoping that the Arctic Silver will help my temps a bit. I plan on using a very soft bristle tooth brush or paint brush to clean the Zalman fan blades. Any suggestions here? Thank you.

Get a can of compressed air at Best Buy (or Circuit City, Radio Shack, etc.) and go to town. Will be more efficient all-around at cleaning each blade. Perfectly save for all other components, too (behind the MoBo, inside the PSU, etc.).
 
Okay project complete. I sure feel better about the cleaner Zalman cooler. Idle temps are now around 46-47 C while reaching 65 C upon load. It seems the clean Zalman and Arctic Silver 5 helped a little bit. I appreciate everyone's help with this!
 
I got some information from the internet and it says the maximum processor temperature is the following:

Intel Pentium D 820 -- 63° Celsius
Intel Pentium D 830 & 840 -- 69.8° Celsius

This information is obviously wrong correct?

I think so since mine has run fine now since May-2005 and at the temps mentioned in my original post.....50 C idle and spiking around 70 C at load. I have no regrets with this setup as it is my first OC. I do plan on building a new rig soon and giving this one to my wife and kids. Not a bad "guest" PC I suppose.

Correct, 2 Gig. D's can handle higher than that. Without definitive numbers, I'd bet on D's seeing high-70's, low-80's before the auto-shutdown.

I hate the stigmata D's get. Sure, they aren't as efficient as the Core-series, but they'll hold their own against several CPU's still in use today. All it takes is a bit of finess and know-how and they really do shine:)

So all Pentium D models from the 960 down to the 805 could likely handle 76 Celsius without damage?

I'm not certain about sustained, long-term operating at that high of a temp, but they should be able to reach it before they go into self-preservation mode and shutdown. To reference another Post of mine, my car *can* operate at 6,000 RPM if I needed it to, but it's not something I'd normally want to do every day for miles on end.

Also, keep in mind that the 800's were 90nm and the 900's were 65nm, so there may be slight max sustained-use temp and absolute max temp between the two, but only by 2-3*C.

FWIW, I had my old D840 up to around 73 in another system once before moving it to a different case with more airflow, where it happily sits at 37*C in a very warm store. It *did* auto-shutdown a few seconds later (wasn't watching SpeedFan, only happened to glance as it shut down, and the temp was either 76 or 78 - too quick to focus in on), but I don't remember if that was BIOS cutting the plug, or if the CPU itself said 'Ummm...no'.
