OT: CPU Temperature due to SETI

Hi!

I've got a temperature problem (i guess) with my Athlon Palomino XP 2000+ on a MSI K7T266-Pro board. If I run the CPU as it is with standard fan (boxed version) I got these results (using AIDA32)

CPU temp (100% with SETI): 69°C / 156°F
Board temp (100% with SETI): 57°C / 135°F
Room temp 34°C (and yeah, we have a damn heatwave in Germany *sweat*)



Usually I have my case open and a big fan (normaly used for cooling my room) pointing directly into the case

CPU temp (100% with SETI): 57°C / 135°F
Board temp (100% with SETI): 46°C / 115°F
Room temp 36°C (2more degrees cause my fan is cooling the case :*sweat sweat* )




While Idle (with the extra fan) I get that:

CPU temp (100% with SETI): 53°C / 127°F
Board temp (100% with SETI): 43°C / 109°F



So here's my question: AMD says that the max temp for my CPU is 90°C. Some ppl say that a critical temp for an Athlon Palomino XP 2000+ is 60 °C. Mine runs at 69°C (w/o extra fan) or 57°C (with extra fan) and at 100% CPU usage due to SETI@home. Am I risking some damage to my CPU with that temperatures? My machine is running 24/7.


Any help or comment appreciated!

There's your answer, unless your system hangs around 90, nothing to worry about.

I know, but I read that the sensor for the CPU temp sometimes is placed on the DIE, sometimes above it. Those that r above measure the temp to low, up to 20°C low. So if that is the case and i add 20°C to my highest temp i have 89°C (!) which is VERY close to 90°C, the absolute max!

And although your car has a rpm max at maybe 8000 u wouldn't drive it that high all the time, woulnd't u? 😉

He may not have A/C in Germany. It usually doesn't get that hot, at least not like in the Southern US. You couldn't live without it in Pensacola!

Christian, I have over a dozen boxes running Seti@Home. I stopped checking the temp 2 years ago. The whole time I was worrying about the temp the systems kept running. I turn off the temp monitor, they are still running and I don't worry about it. Now I make adjustments if a system hangs a couple of times. Recently one stated giving me problems and it turned out that the HS grease needed replacing. Once replaced it was back running at max OC speed.

Good luck mein Freund!

BTW: Ich liebe Deutschland! I spent 4 years there in the 70's. I was in Baumholder and Frankfurt Am Main. 🙂

 
Temps don't sound right, i know i have window fans, so the heat has somewhere to go or else my rigs would heat the room up 35C+ easily.

Get a better HSF, and it sounds like you need some more case ventilation since the MB temperature was so high, it should only be a few degress C above room temp, unless the HSF is blowing some massive hot air on the MB HSF, which might be whats happeneing.
 
Thx a lot guys for the ideas and help:


@ freewolf: JWMiddleton is right, it is absolutly unusual for Germany to have an A/C in private houses, though right now i'd give all my SETI results for one 😉


@OverVolt: i think you're right here. maybe i gonna cut a hole into my case side and place an 80mm fan there


@JWMiddleton: Nice to hear that u love Germany and actually spent some time there. Frankfurt is a nice town, no doubt! U know, usually I don't care about the temp as well, but as we have this damn heatwave here at the moment, I was curious if that also raises my system temp and then i was kinda shocked to see how high the temp actually was. I mean,I never got any system hangs or spontaneous reboots. It's all running smooth and stable. Maybe if I start getting problems in that direction I must think about the prob again.


Does anybody of u know if higher temps decrease the lifespan of a CPU in a noticable way? I mean, of course they do, but is it like only 10 years of life instead of 11 (just example) or more severe like only 50% of estimated lifespan of a CPU?


Thx again TeAm!!
 
I think I could live without A/C in Pensacola.. I just wouldn't want to live without it. 😉

As for the topic at hand, at the time I had my own dual XP1700+ rig, I used Arctic Silver with a pair of Thermaltake Volcano 6cu HSFs and never had a problem, even with SETI running full bore and the case closed. 🙂
 
you need a new HSF and AS3.
problem solved.
no muss no fuss.
i had to lower my OC recently, i was doing the same as you with a big fan pointed into the open case
but i think my video card fan wasnt turning due to the dust! or at least not spinning @ full speed.
at that point i said no more and closed my case.
 
..... hmm ......


..... OK .......


.... got me convinced ....


I gonna give that ArcticSilver III a try. I mean, it can't be worse than now 😉 With a new HSF that'll happen next month when there's some more money on my bank account 😉

And I'm really looking forward to using my big fan for cooling my room again!!

Have never had a CPU chip die from heat and have all of the different generations of chips that I have had running 24/7 since 1986.
Last year when I thought I had an Intel chip die from heat because the Fan on the HSF failed but it turned out to be the Motherboard that failed from the heat around the CPU as it caused the Caps around the CPU to fail. The CPU chip was fine. JW will confirm this, it was actually one of his original systems that I had running in the attic last year in 150 degree heat.

The board that blew the caps was known to have problems (Abit BE6-II.) I found a site that fixes them for $50 (shipping included), but I can buy an ECS board that that and get twice as many WUs.

The 90C is referring to cpu die temperature ,not to temps just away from the cpu as many mbrds measure them ,thats where the 60C comes from ,your cpu is running real hot if your getting that from an external sensor ,however if your getting that from measuring temps via the on die thermal diode then you have nothing to worry about.

So the big question is ,how is your mbrd measuring CPU temps?

Inccidently BMC ,I'm in the UK & sharing the same heatwave as you ,it sucks doesn't it!? (misery loves company😉)
Oh yeah ,& my CPU temp was peaking at about 61C with case temps at 38C (outside temp was about 35C) ,I have MBM measure CPU temp via the thermal diode on my Nfrc2 mbrd, so far so good😉

@Assimilator1: So we're kinda brothers in SETI and heat !?! 😉

I'm aware of what u wrote and I wrote it in my thread as well. The problem is that I have NO idea how my board meassures the temp. It's a MSI K7T266-Pro I bought second hand so I got no manual. MSI site doesn't say anything about that (neither does the online manual).

Any clue what kind of sensor I got on that mobo?
 
Board-temp should be an indication of how hot it's inside the case. If this sensor isn't misplaced, like next to the cpu, a temperature of 57 is too high. Most cd/dvd has max-temp of 45-50, and hd 50-55. Looking on my old, non-working cd-burner, it's max 40... probably one of the reasons it's not working any longer. 😱
Looking on one of my hd's, this recommends 35 normally, but for short periods max 50.

The cpu-temp of 69 is on the high-end, but this is most likely coming from the internal cpu-sensor and therefore no problem till "normal" weather is back...


Uhm, ac? Well, I guess he's running his computer on 230 V AC 😉

Thankfully it's not been so hot up here lately. 🙂
 
BMC
If that mbrd uses the VIA KT266 or KT266a chipset then it won't be reading the CPU internal diode because it can't!.In which case your running damn hot @69C!

Btw what program are you using to observe temps?

Yip, it's a VIA KT266 chipset. Where u know from that it is not the internal diode reading the temp? Any link?

I'm using AIDA32 and the BIOS to look at the temps.

They both show the same: approx. 44°C / 111°F for sys temp and approx. 54°C / 129 °F for CPU temp. Both with my big fan blowing into the case. So i think with that fani'm on the safe side but w/o ... I dunno 😕


 
I remeber another thing.

As I have the Palomino core Athlon isn't it true that that one was not created in 13 micron and with that it uses more power and with that gets more hot than the other Athlons?
 
I just saw my system has been running without the power supply fan running, only the CPU fan was running. Don't know how long it's been like this. I pulled the power supply out cleaned and oiled the fan bearing and put it back in.
 
Lucky your PSU didn't go *pow*!:Q

🙂

BMC
Yeah the Palominos put out more heat than the Thorough Breds but less than the Thunder Birds

Re link for VIA 266/266a ,god I can't remember where I read that!😱 ,it may of been one of Anandtechs reviews of the KT266a or maybe the KT333?
Hmm!?
 
Well afaik the 266 meassures the temp from below the CPU, not directly above it, like some others do or even internally.

I think I just gonna wait till next month (=new cash on my account 😉 ) and the gonna fetch me a ASIII and good new HSF. That'll do the job.

And besided I REALLY (REALLY REALLY REALLY) wanna get my big fan back for cooling ME ( ME ME ME ) and not the damn machine. Cause soon I'm gonna overheat as well and that damage is permanent 😉


Thx TeAm, thx Assimilator1 and thx JWMiddleton!!!
