PIII-S based server
I just upgraded my Tualeron-based server (the one in this thread) to a 1.4Ghz PII-S. This is the 512kb cache Tualatin PIII server CPU.
All other specs are the same and this CPU is running 2-3C cooler under load than my OCed 1.1A Tualeron was.
This thing benchmarks like a 1.8-2.0 P4. I don't think you can run a P4 as quiet as this PIII-S. This thing puts out about 34W and the P4 puts out 58-62W.

Re: PIII-S based server
I put together a Celeron 1.7 system for a friend of mine. I'm not sure what the heat dissapation of that is.. but I think its around 50W? Its not the Northwood core... and its 1.7V I believe.... 0.18 micron?
But its just strange. Cause we're both using the same powersupply setup, and my temps are like 45oC idle (Thermaltake AX7 + 7V L1A).
And the Celeron 1.7 idle temps are like 34oC with the retail fan spinning at 1400 RPM (its running at 6 volts using ASUS Q-Fan). Both computers were running in the same room before..
So that is what kind of puzzles me

I think it was because the BIOS version was older, and it let me adjust in VOLTAGE rather than in FRACTION.. i thought it was strange too because all the documentation I saw on Q-Fan was in fractions. I never measured the output, but ASUS probe reports the FAN at 1400-1500 rpm.
This was a P4B-533VML board.. I believe Bios 1003. People say that the newer ones run the fan at a higher minimum speed.. so I didn't bother with upgrading the BIOS.
Cheers

I like your idea of quiet cooling tualatins.
I have a Athlon XP 1800+. That is being cooled by an Alphatech PAL8045 heatsink, with a Noiseblocker ultrasilent fan, at about 1000rpm at 5v.
The CPU temperatures I get are 30C idle, 42C full load, using the motherboard's CPU cooling tool.
My question is: If I can get these results on a CPU which puts out about 60W, wouldn't it be possible to cool a tualatin fanless, if it puts out half this value?
My interest in this has been aroused, as I recently saw a dual socket 370 for sale really cheaply, but I have little knowledge about the cooling requirements for those CPUs.
Thanks,
Graham

Maybe but I bet your temps would be pretty toasty. You's certainly need some good airflow in that case.ghowarth wrote:I like your idea of quiet cooling tualatins.

If you use an SLK-800 with a 5-volted Panaflo L1A you'd get much better cooling with hardly any noise. You have to have some awesomely quiet components in that thing to hear a 5-volted L1A.
I'm running a 7-volted M1A on my SLK-800 and can't hear it over 12" away with the case side off and I can't hear it at all with the case side on.
