How hot does your Coppermines become?

[Technoid]

I have accuired a PII 800EB and I think the HS we recived with it is rather small.

It's a Coolermaster "DP5-5F11" and according to the Cpu onboard sensor it goes somewhere abowe 65 degres Celsius.

Intel says that they are good up to 80C but i wonder.

I ahve checked Coolermasters site and the HS is rated up to 866MHz.

But it would be great to know how hot others Coppermines becomes.

Thanks in advance.

I think you're on the high side. How high depends on how you got that temperature.

If your motherboard supports the Coppermine's built-in temperature monitoring feature (VIA Apollo Pro 133A boards do), and if that temperature was recorded when the CPU is under load, your on the high side. If you're using a BX board, which doesn't support the feature, you're probably way too high.

Under load, using an Asus P3V4X (which gets the chip temperature directly from the chip), the temperatures on my overclocked PIII 700 tend to fluctuate from 45 to 58C.

Ambient room temperature is around 70F/21C. I'm using a Globalwin heatsink and a silver-based grease.

well, mine runs at 58f, but it has beast on it

PII 800EB? You mean PIII?
My CPUs get to around 41-45C.
Back when I used 500 MHz they were a good 10C warmer.

My Atlas IV HD is at 26C right now.
I can't want to finally get a new aluminium rack with SCA connectors so I can put in the Atlas 10k II. I don't dare using it without extra cooling.

There you go, Technoid. Five response. Five radically different results. Our methologies are different, and Jim has a nuclear powered heatsink that keeps his CPU below room temperature.

I'd say, given the variety of results, that your somewhat high or way too high, depending on your methodology.

What I've found is (and I'm not sure if that's what's happening here. These are just my personal observations) get a reading directly from the CPU's built in sensor, and temperatures tend to be in the 50's. Use a thermistor and stick it inbetween the heatsink and the PCB and temperatures and temperatures tend to be in the 40's. Use a BX board's CPU temperature monitoring feature, without a thermistor, and temperatures tend to top out in the 30's.

Use exotic cooling, like a Peltier, and your CPU temperature may drop below room temperature.

It's all relative.

Here's Intel's page on the subject:

... and don't forget that these reportings didn't include the ambient temperatures which can greatly affect chip temperature readings.

[DarkSyd]

Ambient room temp ~22C, mobo temp 26C (pretty much constant), CPU at 24 idle, maxes at ~42 under load (depending on whether I burnt supper or not).

700e at 933, 1.8v, Alpha PAL35.

The Coolermasters don't have bad fans (small, but high rpm), but the heatsink doesn't have near enough mass to cut it as a quality cooler. It cracks me up that most people's oc'd rigs run cooler than stock ones

[Technoid]

the P3800 @ 133 is not that much hotter than a 700 @ 100 with the same HS!
The P3 700 was 5 degres cooler.

All of these checked with an MSI6337 I815 MB.
The wendor we get these sinks from doesent have a clue at all.
they claime that they will work up to 933MHz!

They have repeatedly sent me SECC2 collers when i have ordered Athlon coolers.

But It survived 15 hours of 99% load!!!

Going to get a better HS altough!

"... and don't forget that these reportings didn't include the ambient temperatures which can greatly affect chip temperature readings."

This confirms my suspicion that I am far too long-winded, and no one reads my posts to the end.

Yes Paul, you did very well. See class, you can all learn from Paul's example.

If you haven't noticed, I've been on a crusade these last few weeks to get people to get into the habit of telling a more complete story when it comes to temperature readings. It just makes these comparisons a bit more meaningful. Sorry Paul ... I should have pointed out your thoroughness.

[ALBPM]

DAMN!!!! My ears are burning....LOL

Oh!! He means the other Paul...LOL

Xortam got me too awhile back.

I just made a modification to my cooling setup. I was running a P3-800 FCPGA with an Alpha PEP66 on a ABIT BX133 mobo.

I was running at 1.85v, 125MHZ FSB @ 1000MHz. My temps were-->Room temp= 23 degC, Case temp= 30 degC, mobo temp= 32 degC, CPU temp range= 32-38 degC.

Yesterday I installed a 52 watt Leufkins Peltier kit on my PEP66. I am now running at 1.9v, 129MHz @ 1032MHz very stable.
My new temps are-->Room temp= 23 degC, Case temp= 30 degC, mobo temp= 32 degC, CPU temp range= 19-24 degC-->idle to full load.

The 52 watt peltier is a conservative effort for a P3 and I don't think I'll have a freezing and condensation problem with this.

Paul

[xortam]

Now thats cool! It will be interesting to see what that Peltier does on a scorcher of a day. I'd guess you may still get one of those in the next month. How hot does your room get ... worst case? I thought I read that the P3-800 wasn't a great O/C'er. I guess you proved that wrong. Are the faster P3 CPUs worth trying to OC? I wonder if I could get the 800 to work in my Asus P2B-S, v1.03?
