[18:45]<kyddja>Do you also regularly get "light" heart attacks that make you unable to move and breath for like a minute?
[18:45]<svjgnpysx>50c isn't an unreasonable temperature for most chips. Warm, sure, but not burning.
[18:46]<kyddja>I have had that since I was little... I just had one.
[18:46]<caayza>Stonefish: CPU? P4, socket 478 or whatever
[18:46]<kyddja>It feels as if I would die if I were to breath freely.
[18:46]<caayza>1.8GHz
[18:46]<kyddja>Neptune__: Yeah...
[18:46]<svjgnpysx>I'm less familiar with p4's, but I'm fairly certain that's a very low alarm temp
[18:46]<caayza>Stonefish: the alarm is adjustable. I'm more interested in how fast it heats up than how hot it gets
[18:47]<trssyud>My box is (if you can believe the built-in sensors) running at 51 degC right now
[18:47]<caayza>the CPU _Kernel_ temp was like 78C
[18:47]<gglvugg__>kojiro - thats on the hot side...
[18:47]<caayza>this box records 3 temps. It calls them "System temp, CPU temp, and CPU kernel temp"
[18:47]<gglvugg__>probably true if its the die temp sensor
[18:47]<svjgnpysx>Kernel temp.... what's that mean?
[18:47]<caayza>I dunno
[18:48]<caayza>but it's usually about 28 degrees above the CPU temp
[18:48]<svjgnpysx>Does your board have one of those thermometers UNDER the chip, on wires inside the socket?
[18:48]<gglvugg__>CPU temp is on the mobo cpu socket - CPU kernal temp is the CPU itself
[18:48]<caayza>and it's kinda hard to believe, because by the time I get to the BIOS, after the computer's been off a couple days, it's already above 60C
[18:48]<gglvugg__>kojiro - totally normal
[18:48]<caayza>k
[18:48]<gglvugg__>i mean that it gets hot that fast
[18:49]<trssyud>As long as the magic smoke doesn't come out, you're golden.
[18:49]<caayza>heh
[18:49]<caayza>Oh, on another subject, can a non ECC system handle ECC RAM and just ignore the parity bit?
[18:49]<gglvugg__>Tassium - well not quite - running too hot for a long time wont smoke the CPU, it will shorten its life though.
[18:49]<caayza>or is that insane?
[18:49]<gglvugg__>kojiro - afaik that wont work
[18:49]<caayza>k
[18:50]<trssyud>Neptune__: Dangit, my joke was already lame enough without you spoiling it
[18:50]<svjgnpysx>I know the older AMD chips were guaranteed not to take any form of damage until 90c. I don't know about new/intel stuff.
[18:50]<caayza>Yes, I know about the magic smoke. I bought some when I assembled this computer :-P
[18:50]<gnvdrsc>hello
[18:50]<trssyud>netmask: Howdy
[18:50]<caayza>This isn't a new intel chip, it's several years old
[18:50]<slcjd2>magic smoke refills?
[18:50]<caayza>SpComb: hehe
[18:50]<gnvdrsc>hello
[18:50]<svjgnpysx>kojiro: new amd, or any intel. I don't know how they work :)
[18:51]<trssyud>SpComb: Just like inkjet cartridges, the magic smoke is never supposed to be refilled ;)
[18:51]<gglvugg__>Stonefish - yah, the new intel thermal specs recomand a max sys temp of 38°C
[18:51]<caayza>Stonefish: oic
[18:51]<svjgnpysx>wtf...
[18:51]<caayza>Neptune__: that's a bit ... optimistic, isn't it?
[18:51]<svjgnpysx>Shit, it hits 38c ambient here :)
[18:51]<gglvugg__>kojiro - the air in the case should be 38°C - CPU is 70°C afaik
[18:51]<trssyud>Time to move to refrigerated cases
[18:51]<caayza>Neptune__: er... CPU or 'kernel' ? ;-/
[18:52]<svjgnpysx>Your colonel should always be kept refrigerated.
[18:52]<caayza>I'll turn the box on and check the "system" (case) temp
[18:52]<gglvugg__>kojiro - don't know - you'll have to dig up those thermal specs
[18:53]<caayza>It's a pretty nice Mobo -- I just wish the temp alarm were silent. it's _supposed_ to just gradually underclock the CPU when the temp gets too high
[18:54]<caayza>I set the alarm for 70C now
[18:54]<trssyud>Have you considered buying a tea kettle and just listening for the whistle?
[18:54]<svjgnpysx>kojiro: Alarm means alarm. The throttling should be independant.
[18:54]<caayza>Tassium: something tells me 212F is a bit much :-P
[18:54]<trssyud>kojiro: I am a man of excesses ;)
[18:55]<svjgnpysx>kettle will go at 100c. that's definitely burning time :)
[18:55]<svjgnpysx>Though it WOULD make a nice watercooling mod. a whistle attachment :)
[18:55]<trssyud>Ah, that's assuming you're at sea level
[18:55]<vajusc>Tassium: Indeed (:
[18:55]<svjgnpysx>There's always one... :)
[18:55]<caayza>Sys/CPU/Kern = 34/44/76C ATM
[18:55]<gglvugg__>Tassium - when was the last time you climed mt. everest with a watercooled computer?
[18:56]<gglvugg__>:P
[18:56]<vajusc>heh
[18:56]<trssyud>Neptune__: I'm doin' it next week
[18:56]<trssyud>I'll send pictures.
[18:56]<gglvugg__>ok.
[18:56]<svjgnpysx>kojiro: How's your heatsink looking?
[18:56]<caayza>Stonefish: it's glowing a dark red
[18:56]<caayza><_<
[18:57]<svjgnpysx>spinning nicely, seated well, minimal thermal paste?
[18:57]<gglvugg__>kojiro - iron, aluminum or copper? :P
[18:57]<caayza>alum
[18:57]<caayza>what should I be looking for?
[18:57]<svjgnpysx>a new PC :)
[18:57]<caayza>Stonefish: yes, spinning quietly at 2352RPM
[18:57]<trssyud>Stonefish: I should hope the heatsink isn't spinning
[18:57]<svjgnpysx>a bit low, but okay
[18:57]<caayza>it'll get faster as it heats up
[18:58]<caayza>top speed is 3800 IIRC
[18:58]<svjgnpysx>oh, retardofan
[18:58]<caayza>there are three sysfans
[18:58]<svjgnpysx>3800 will do
[18:58]<gglvugg__>kojiro - are you using heat transfer pads or thermal grease?
[18:58]<svjgnpysx>Mine does 3800. case is 32, cpu is 39
[18:59]<caayza>it's been a while since I set it up neptune, but it was thermal grease -- arctic silver, IIRC
[18:59]<trssyud>You were sparing with it, right?
[18:59]<svjgnpysx>kojiro: Here's the $64m question. How much silver did you use?
[18:59]<caayza>Stonefish: not much. a "dollop"
[18:59]<trssyud>Is that a metric dollop?
[18:59]<svjgnpysx>can you quantify that?
[19:00]<caayza>Stonefish: no
[19:00]<gglvugg__>how many mm² ;)
[19:00]<caayza>it was several years ago
[19:00]<svjgnpysx>that's problem #1
[19:00]<svjgnpysx>Take it off, clean both surfaces with rubbing alcohol, reapply DAMNED sparingly
[19:01]<svjgnpysx>You don't even want a complete layer
