Prime95 heat!

[hofinder23]

i have a 3200 venice overclocked to 2.6 ghz at 1.525 V. arctic silver 5 is on with a ok hsf.

after playing a hour of half life 2 my cpu runs at 50 C... it idles around 42 C. however, after running prime95 for 22 hours without an error my cpu is at 59 C? is that too hot??? is this normal?

EDIT: by the way my system (mobo) temp is about 31 C while the cpu is 59C.

any suggestions on what i should do?

 

[ElTorrente]

that's pretty effin hot.

 

[Hacp]

59 is acceptable.

Unless you prime 24/7 it doesnt make a difference how hot it runs under that load. Lowering the voltage would help, as would a better cooler, but i wouldnt worry about it.

 

[aatf510]

Nothing to worry about unless it gets over 65C

 

[ericlala]

thats average for full load

 

[coomar]

thats pretty much the performance the stock cooler will give you

 

[exar333]

get a better hsf/fan?

 

[aka1nas]

Thats a little on the hot side but probably to be expected with that much of an OC. Try dropping the voltage a little and see how high you can still OC. It might be worth it to lose 50Mhz or so if it lets you run at a significant lower temp(My 3000+@2.5Ghz only hits 52C on full sustained load for example.).

your okay man...it's not that bad. My sempron 3100+ sempron (paris) OC @ 2.069 Ghz is running @ 52 C at load, 35-40 idle (depending on how hot my room is, it's really freaking hot :Q ). But anyways, just make sure it doesn't go above the chips maximum temp load (manufacturer's specs)...

btw..i'm using a stock HSF

My 3000+ only runs about 45-47*C under P95 Large-FTT load.

Get an XP-90C with a Panaflo 92mm fan. Works wonders!

 

[CaBoOse999]

That seem pretty decent. Back before I got watercooling my temps use to get up to 62C with my 3200 winchester at 2.55 with a voltage of 1.5 with stock cooling, that was where i drew the line.

 

[ssvegeta1010]

59C is perfectly fine. Over 65C is the ony place where you should be worrying about temps.

thanks for all your replies

i guess i should've stated the HSF i was using on my processor. it's an arctic cooling silencer ultra 64 which is a little better than the stock HSF.

what's strange was it was running at 52 C at the 12 hour mark.... I thought that was the highest it would go at under load since it was at 52 C after playing a hour+ of half life 2. but after checking it again at around the 20th hour it was around 59 C. has anyone else had similar experiences when testing prime95 for 20+ hours?

I ran it for 59 hours once and after about an hour it hit a peak temp and never rose above it. Maybe ambient temps had something to do with it rising over 52C?

If you want air cooling, get a thermaltake big typhoon, they do better than the thermalright xp90 or xp120. And you dont need to buy a 120mm fan seperately like the thermalrights which add to the total cost. Not to mention the big typhoon is silent too.

i don't think it's the ambient temp because i started it at 12 AM Sunday night (about 60 F).... checked at around 11-12 PM Monday morning.... and the 2nd time i checked was at 8-9 PM when it was pretty cool (60-70 F again). i turned it off at 10 PM. i'm just not sure why all of the sudden it decided to go another 7 C higher after being there for 12 hours....

i'm at work right now, but when i get back i'll try to lower the voltage to 1.5 (currently at 1.525).

Don't worry, 59C is fine for full load.

i'm afraid that running at this heat will significantly lower my cpu life. if it does lower the life... how much would it lower the life by?

Don't know. There's no way to measure exactly how much CPU life you lose by running on increased heat. At 2.6 with prime95 cooking away at small FFTs, 59C load wouldn't worry me much. Besides, you won't be running at 59C during normal computer usage. You said you hit 50C while playing HL2? I think that's the highest you're going to see 99% of the time. Your voltage isn't very high, either, so that shouldn't have a large enough impact on your CPU life that you'd notice. To be safe, I'd say your chip should be good for 3-5 years running like that.

Seems like one of the guys that reviewed your HSF said it didn't cool well enough. I'm not sure how well an aluminum arctic cooler HSF built for silence would work...I'm assuming it would dissipate less heat than a stock AMD HSF if it were aimed at the silent crowd. Personally, I would have picked up a Zalman 7000/7700 Al-Cu series HSF for practically the same price. The Zalmans are damn quiet, but their cooling capability is very good.

Let me put it this way. You will find yourself making a keychain out of that CPU or giving it away before you'd need to worry about shortening its lifespan.

Sweet, time to increase my OC. Currently I'm doing 2.5ghz at 1.5v on a 3000 venice using a zalman 7000, and I'm getting around 52C at full load. I know it can do 2.63 at 1.52 and still be about 55C. Maybe I can reach 2.7...

 

[hofinder23]

well i dropped my voltage down to 1.5 V..... (no problems) started running prime95 again and within a couple of minutes it starts getting up to 58C. i touched my heat sink and it only feels warm.

did i not put on my AS5 right? i put only a little in the middle of the cpu and smashed it together like instructions say. or do aluminum HS not cool down fast enough for this kind of OCing??

 

[imported_hotchip]

Sorry to gatecrash
I have a similar problem with an AMD 3000+ (Venice)
My chip went to the max (65degs) or at least 60-64 constantly before hitting 65 and shutting the computer down, restarting again at 65 before i shut it down and kept it off. Doesnt appear to have done any damage. Looks like if its a newer motherboard they automatically cut the computer to protect the CPU?

had to invest a little in lowering the case and CPU temp
got some yastech 125 cfm fans (which look like they do the job but sound like a mini jet engine)
installed a PCI fan card which im sure isnt moving much air at 33cfm

removed the cheap cpu fan with a Vaporchill (copper base) and Arctic Silver 5 and temps although around 52-54degs (57 load) looks more stable than it was before.

Im sure i could lower the temp more by lowering the voltage? How can i check or lower it?

thanks!

I dont think you have a problem but you could try reseating the heatsink. Different heatsinks have a different thermal dissipation "capacity" (that's not the correct word but it fits, somewhat) and aluminum ones have a pretty low one.

Hotchip: If you're running at stock (or at less than 1.7v) then you need to reseat your heatsink for sure. How much artic silver are you using? You need to use very little.
