Temperatures for Duron Procs

Heyo,

I just decided to push my Duron from the good old 600 mark upto the 900 mark. Now before this thing got started overclocking it was running at about 36-40degrees C. But now that I've overclocked it, @ idle it runs at 52-54 degrees C and with EliteForce (Most CPU intensive thing I've got at the moment) it runs at 58 degrees C. Now it never peaked past 58, and everything appears to be working fine (otherwise I wouldn't be able to post this message) but when should I begin to worry.

I guess what my question is, in a typically warm/semi-humid environment where the temperature is generally 25-30 degrees C, what should my CPU temp generally be (Assuming I'm using a Chrome Orb, and 1 intake fan)

Thanks,

Hi,
My Duron 600@900 runs 52c full load(which is always with rc5). The motherboard temp is 28c.

I've been running it like that since I bought it.

I was getting nervous actually.

So I'm assuming then that the average Peak temperature should be around 50C?

What else would you recommend in the way of cooling. I know the Orb's aren't the best coolers, but I got a good deal on it (10 bucks canadian).

I'm running a Duron 600@915 @ 1.85VCORE and it does the dance at 35C under full load (RC5 24-7) and the system temp is 21C. I don't think your temps are out of spec, but I certainly wouldn't let my machine run that hot! ;) Try some more case fans, or even better, leave your cover off! Also, reapply the thermal compount on the bottom of your orb. (If it has one of those pads, scrape it off and use some real compound) Good Luck!

Fish 54 What are you using for cooling? I've got my 660 at 841 (1.05 x 8) and it runs between 46 and 49 degrees. Even at 600 it was in the 30's. I've got the front fan, rear fan, PS fan and the retail HSF.

Upper 50 to low 60's is no problem for this CPU, especially if you are running an Abit KT7. If setup correctly, the temperature probe should be slightly bent, yet still extend above the CPU socket. Firmly pressing on the CPU when inserting will push the probe down the rest of the way, yet will maintain absolute contact. This will give an acurate reading. Previous boards (and this one if done incorrectly), had the probe a good 1/8" away from the bottom center of the CPU, so temperature would be a lot lower. Besides that, this CPU is MADE to run hotter.

Reminds me of all the people that were used to cars running at 165 degrees, and then they get a new car that is made to run at 195 degrees, so they think it is too hot, and try to lower it. This Duron is rated at up to 90 degrees Celsius, which is 10 degrees Celsius hotter than any other CPU. Add in the fact that you are getting a "true" temperature reading by having the probe touching the CPU, and it is no wonder that it is 10 to 20 degrees hotter than what "used to be" considered normal. Geez, some Video cards today run 40 to 50 degrees Celsius (3dfx is one that comes to mind).

Has anyone ever reported a problem due to temperature yet with these Durons? I have seen posts of users running them at 75 degrees Celsius for a couple hours by mistake, and the thing never blinked. Also saw 1 poster had it over 100 for a few seconds, and that didn't trash it either.

Well I figured the processor should be able to run at temperatures past the 50C mark, otherwise it wouldn't be much of a processor.

So I managed to get my @idle temp down to 50C or so, going to let it idle and see what the Asus utility sais. Got both of my case fans going now, so that brought down the case temp to about 29C or so...

As soon as I've got a few minutes of idle recorded I think I'll see how hot this thing runs. But I don't see any physical way of cooling the processor down to 30 or so, as that would require some MASSIVE fan action...

(Was almost tempted to aim my 19inch rotory fan at it for a while and see if that helps :) )

Thanks to all who replied.

It doesn't really matter what temp it is running at as long as it is stable. Different people are going to have different readings. If it is having heat problems, you would know. You can't really rely on the temperature probes to be completely accurate. Even if the probes report the temp to be 20 degrees lower than the actual on-die temp, then it could be up as high as 70 degrees. Anyway, that's just my 2 cents.

Cyridian,
ORBs just don't do that good a job on Duron/TBIRDS. For $10c you may even have an ORB knock off ??. What mobo do you have. The ORB doesn't fit on a KT7 unless you hack off some of the heatsink OR install it backwards. Also many ORBs have 2 layers fo protective film covering the thermal compound, easy to miss to second layer.

My 600@850 runs seemingly fine at 58-62C under full load w/ retail HS&F.

I'm not concerned about the temp. It's only a $60 part. If it fries, I just buy another. I remain unconvinced that it will fry, though. Time will tell.

My setup: A7V rev 1.01. Temp probe in contact w/die.

You're absolutely correct. All Socket A mb's use a under socket thermistor to report cpu temp. They are highly effected by air temp(more so that cpu core temp is) and measure dead substrate temp. They are tremendously inaccurate, so comparing duron/t-bird temps isn't a reliable thing. ONe person could have the thermistor under the core(still way off of core temp), but another could have the thermistor underneath the l2 cache, which would be even cooler. Both would be wrong, but you can't compare the two results with each other.

As long as the cpu is running fine, i wouldn't worry about it. But when it comes to sharing cpu temps, the readings with these mb's aren't accurate(or consistent).

RobsTV,

Even if the thermistor is touching the back of the cpu, what is it really touching? Completely IDLE SUBSTRATE. Flip Chips reverse the socket cpu manufacturing process, putting the hottest part not underneath the socket, but rather contacting the heatsink. Even if it is touching, it is a wildly inaccurate reading. YOu don't read the sudden cpu temp changes when going from idle to full load. You are also still measuring substrate. TO mistake this for measuring core temp is inaccurate.

Is the builtin thermister diode in Intel P3 line accurate? Cause i've seena guy get 90 degrees C for his 933Mhz. Pretty weird huh? Still, he reports no problems except for the interesting reading.

the diode built into a p3 is highly dependant on the mb reading it. They are, however, more accurate in general than an under cpu thermistor that's touching substrate, because at least the diode is imbedded in the cpu core.

Just re-inforcing lostnthenet's and mikewarrior2's comments re you shouldn't...
**compare temps of different systems
**don't worry if your system is stable
because no sensor location we've ever heard about measures Tcase top center, or Tflipchip top center...where the "only" max temp is "specified" by both AMD and Intel.

"jinsonxu et al, re Intel's thermal diodes....
**They are inaccurate, Intel says so, read their app notes re thermal diodes...no, they don't say how inaccurate, just that diode "ideality factors vary significantly.
**Even if they were accurate, are relatively useless, since "nowhere" does Intel ever spec what Tdiode max IS for any of their chips. Can only use then, to sense "change over time"...just like other mobo sensors...albeit with faster response.
John C.

PS:- Consider this...1st mobo mfr installed sensor as marketing ploy,
all others followed, "me too", not to lose sales. But none of them measure a "cpu temp" you can compare to chip mfrs' absolute max specs...as stated so well by lostnthenet and mike warrior2.

In my Via Hardware Monitor, it says that my cpu is running at 54C and the system temp is 25C. And I know that 54C is really high because I haven't even OC my Duron 600 yet. The system fan is running at 4854 RPMs and then the cpu fan is running at 0 RPMs. But I opened up my case and everything seems to be spinning...anyone have any ideas.

If they say your CPU fan is at 0 rpm, then you probably didn't plug the fan connection onto the motherboard header, instead, connecting directly to the ps instead. But i remember someone posting about connecting the yellow wire to the fan header to have the rpm monitoring while wiring the other 2 (red and black) to the PS.

I still think the 4854 RPMs is your CPU fan though. Did you mix it up?

What are you using the measure your temperature?

I know that SiSoft Sandra gives totally inaccurate readings for my motherboard. It states that my CPU is running at 55 C when in actuality- it's running at aroune 32 C. SiSoft adds "compensation" to their temperature readings.

The only truly objective result is to check the temp at standard settings then run for several hours in a room with a constant temp and then check the temps in the overclocked state - assuming all factors are the same.
My old C300 only increased 1 degree from 300 to 450 Mhz... :)
Unless you have the sensors calibrated they could be wildly inaccurate.

I just bought a couple (only using one though :) ) Taisol 1.1 Gig--AMD approved HSF's. Cost all of $11.30 each...

My temperatures went down a bunch from those using the retail HSF....I'm at 850 and 36C now...with case open...it runs a couple of degress warmer with case closed....
