View Full Version : safe cpu temperatures
hi everyone, i have a TB 700mhz @800mhz rite now running at 45 C after an hour of tribes 2...and idles at about 41C ... i was thinkin of overclocking it a little further.. but what's a safe/good temperature to be at? thanks

There's an article by Joe here:

Judging by the temps you listed, you may want to consider improving your cooling before youtry for a faster goal. They will go up and it's good to shoot to hold the max temp to <45C for best results. That's not saying it won't run at higher temps, just less effectively.

I have my Duron 750 @ 910 Mhz (130*7), 1,725V - 62C idle, 71C full load. Stable, but I think too hot - I'm going to shop for better cooler (my **** have 0.8C/W)...
Consider a thermoEngine. Properly lapped, greased and equipped with a quiet YSTech 60mm fan, It should be able to knock 25C off of your temp. You're going to cook the cpu at the rate you're going.

get some good cooling before you lose that chip entirely! those temps are waaaaaaaaaaaaay too hot!!!

What voltage are you running at? If you're running at default or over default, that can create a LOT of heat. Step it down below default and see if it'll boot. If it will, step it down again, and keep doing till it won't boot, then check stability. If its stable, leave it. If its not stable, then raise it again till it is. Its quite touch and go. What are you using as a hsf? No matter what you're using, you want to lap it and add some good Thermal Grease, like Arctic Silver II.
Your pretty 'safe' if your cpu is running under 50c. Of course the lower the better. If you can get it to run stable though while keeping temps under 50, I'd sure try to go higher. <g>.
I'm running 1200@1430 stable high 30's idle low 40's full load. If that helps you.

Can' t cool this Duron.
Changed cooler - got biggest thing I can find there (north-eastern Poland) - a big aluminium radiator with 2 fans, cpu is still hot.
Slowed cpu to 868 MHz (124*7), 1.675 V, temp dropped 3C - 60C idle, 68c loaded.
Chipset has 45-46 C
When case is opened, temp is 5C lower, 40C chipset, about 65C CPU. Closed case is HOT, more than 40C... but I have 28 C in my room.
Still run stable in Win ME
Mainboard is Soltek 75KAV, with anti-burn shield in bios, set to shut down at 75C, this temp was not reached yet ;)

I'd say that your monitoring software is fuxxored . . . . I'd try to get something better.
I think I have bad case.
Power supply has holes under the cpu. There is a pillow of hot air around cpu and it becomes hot. This hot air has no way to escape except a few small holes in the case.
Monitoring soft: VIA Hardware Monitor, Hardware Monitor Pro, BIOS... they don't seem to be f***ed.
Now slowed to 800 (8*100), 1.6 V, 52C idle, 62C loaded. After "cold start" it has about 45C, then temp raises to 52-53, and top of the case is HOT
I plan to change something in this case to make the way out for hot air.

Another question: anyone overclocked cpu cooler fan? I think 17V instead of 12V may help but... maybe I will killl the fan...

I don't think this has anything to do with "Hot air" or anything else. Most likely you have an A7V or A7V133 and the CPU idling feature is not properly enabled.
Read this article (http://www.athlonoc.com/tweakvia1.htm). It will tell you how to lower your CPU idle temperature by another 10-15 degrees. It should also lower your load temperature a bit. Your load temps are a bit on the high side, but they should be fine.
Yes, it was poor cpu cooling software. Idle temp dropped to 33C @ 910 MHz
I reassembled my system so cpu cooler has access to fresh air - load temp don't exceed 68C @ 910 MHz now. Much better.
How much can help this famous "artic silver"? I have a friend in USA who can buy it for me - where to buy this, what is the price and full name?

ArcticSilver2 claims to be 2-7C better than any other thermal compound. Read more about it at http://www.arcticsilver.com/as2.htm.
It costs about $10/syringe(net wt. 3g), if I remember correctly.
There's also a copper-based compound called "Copaslip" made by a british company named Molyslip. I don't know about its availability in Poland, but if it's available in Finland, I'd think it's available quite easily.
I was using it before I bought AS2, but sadly I can't give any reliable comparison info. It shouldn't conduct electricity, as I (still) got some of it over the pins of my MX & it's memories. Still works. Costs about $5/50 grams in a tube, if my memory serves.
Worth a try, IMHO.

Oops. Remove the dot after the address, and it works. Sorry.

I thnk pik33 needs to cut a couple side blowholes in his case and mount 2 120 mm fans in there and also cut 2 60mm for the top. I like to use delta fans 700 rpm but then again i dont mind my cpu sounding like a friggin lawnmower im sure there is a quiet fan out there though that will help you though better than what you are at now so look around or if noise doesnt bother you go for the deltas

If your chipset is at 40C then what you need to work on is cooling your case. That'll bring your temps down more than anything, in this case at least.
Yes, opened case=5C down...
First I have to cool my room, I have 28 C here... but I am not cpu, I love hot room... ;)
Chipset has about 50C after long work @ 130 Mhz FSB.
CPU now don't exceed 70C @ 130*7
Now I'm searching for better thermal grease, hope to drop load temp under 60C...
And after using wcprset idle cpu temp is about 31C... chipset stays much more hot...
System works stable.

Your temps are still too hot. My range is quite acceptable, for reaching the wall.
55C is quite high, but it is stable.
