On LN2 of course from Japan.

seems impressive,
what is a LN2 though? some kind of very efficient cooling system?

Liquid Nitrogen.

LN2, sounds like liquid N2 or liquid nitrogen. That's more than 100 degrees centergrade below zero. Simply put, not practical for use by commoners like us.

thats some crazy [-peep-], you could loose a hand or a foot with that stuff, btw intel showed a pIV running at 4,68Ghz on their developpers forum so thats the recors for me

LN2 is @ -197c approximatly

Wowza, speaks a lot for the headroom 0.13m K7s have. Just like the 0.13m speaks a lot for P4 reaching near 5GHZ. IMO Intel shouldn't be transitioning so early on, wasting all that nice MHZ the 0.13m can still bring.

But still, WOWZA! 3.3GHZ, ouch man. And it did SuperPI. Though I wanted to see some real benchmarks, since I don't know how to measure SuperPI's times and how they compare to other CPUs.

we have some liquid helium here in the lab, it's around 4 Kelvin.....perhaps my Palomino could hit 1.7Ghz with LHe!

my chip's a shoddy overclocker.

Hey Fugger, will you be attempting that OC with your equipment?

I already have a furnace in my house for winter heating. Don't need another one.

Seriously, AMD needs to find a way to turn down the heat generated by their chips.

LMAO Never heard something so ridiculous in my life :/ I use Liquid nitrogen every day in a biology laborotory and its not quite like how films potray it ! You can even stick your hand directly into it for a very short period of time and it will do nothing due to the heat of your hand. It is about -160 btw

And yes you could loose a hand but you would have to be a careless as you would be to get electricuted with your PC ?

glad to make you lough, her's a challenge really try putting youre hand into that stuff, hope you can still use a keyboard afterwards

While the physics of your statement seem to make sense, I'd rather not take the chance myself. I played with LN2 all summer, and I seem to remember frostbite that was caused by splashed LN2 that actually caused a blister... so that's my own personal experience.

Wow, you actually have liquid helium? That's the craziest of the crazy. Don't you need to store it in like 5 walled steel containers that cost thousands of dollars apiece?

Simply, shocked. All of you are talking about LN2 as something quite normal! Well, the cooler I can get is my freezer :-(

Still using air cooling for my XP 1700+ ...

Reply to baldurga

Do you really think that a CPU cooled by LN2 can give a real idea of want can be achieved in the future with AIR cooling?

I know that yields get better and allow to reach higher frecuencies, but IMO a CPU with LN2 is something a very good yield can achieve ... maybe I'm wrong.

Does anybody know of past experiences (Intel or AMD) where the first results achieved with LN2 were later almost common after yields matured?

"Seriously, AMD needs to find a way to turn down the heat generated by their chips."

Actually, the thing that makes them run hotter than Intel chips is the same thing that makes them less expensive than Intel chips. The 80mm squared die size of the Thouroughbred 84mmb of the Tbred B's, and the 128 mm of the Palominos are all smaller than Intel's 131mm squared core. Smaller die means more cores per wafer... it also means less area for heat to be dissipated through... other than the actual materials used and the voltage (which is nearly the same) that's the only difference. AMD has always boasted that their processors are cheaper than Intel's, so I don't see them changing to a larger die to allow for better cooling... I don't see cooling as a huge problem right now anyway... I have an XP2000 with a Palomino core running 96 degrees idle, 107 under full load with a copper heatsink.

yep it costs a lot and we don't have much, it's used for EPR experiments, i don't think they'll let me cool my Palomino with it :)

same here, we freeze out membrane preparations in liquid nitrogen......i like pouring the excess LN2 all over the floor when i'm finished with it :)

Both Intel and AMD need to find ways to do this. The 3 Ghz P4 can theoretically consume more than 100W (<A HREF="http://www.aceshardware.com/read.jsp?id=50000320 " target="_new">http://www.aceshardware.com/read.jsp?id=50000320 </A> ). 100W isnt funny anymore. SOI and/or comparable processes and/or .09 are becomming a bare necessity real soon, especially for intel (AXPs consume considerably less,not more as generally thought. But as someone stated, they are smaller, and hence more difficult to cool).

Whatever happened to the quiet PC? My TRS-80, IBM-XT, 286, and 386 machines didn't have fans or heatsinks. OK, the 486 added passive heat sinks, but they are quiet. The only fan was on the power supply.

The Pentium brought the active cooler to the CPU. At the time I thought "what insanity". If a $5.00 fan fails, you can destroy a $600 chip ( the fans were crap then, and the chips expensive).

I have a run of the mill 900MHZ Athlon, and it has 6 fans: HSF, GPU, Northbridge, Intake, Exhaust and power supply. Madness.... I almost yearn for a quiet VIA C3 (almost, I'm not crazy yet).

why do you think they uproduce such haevy cases lately with all that airflow you pc could take of at any time creating the new phenomenon "the UFPC"

not really intel showed a PIV running at 4.68Ghz in their last developper forum. The thing is that cooling a pc to those temperatures gives it semi superconducting capabilities. PIV will probably go to 3,6 GHZ as said maybe a LIIIItle bit more and then presscot 'll take over using 0,09 tech goal fro prescot is 5Ghz and then...and then... they have to fiind new ways to shake yours and my pockets my friend

I agree.. though the TRS-80 made a terrible noise when it accessed this huge (8" ?) floppy drive :)

Also, you can make todays PCs pretty quiet, if you dont insist on having the fastest pc out there, and dont mind spending a bit more. I have an AXP1800+ cooled by a swiftech with a very slow, barely audible Pabst fan. I added an Enermax 450W variable speed PSU running at minimum speed.. hardly a whisper. My 2 case fans are 7v modded, guess what ? cant hear them. My motherboard -thank god-, doesnt have a northbridge fan, its just my GF4 fan that still makes some noise, but Im considering replacing the fan with a Zalman passive cooler (looks cool too :).

All in all, the only thing that really makes some noise, are my 3 7200 rpm harddisks (incapsulated in a cork case :p). But if they go to standby, I swear I have to look at my case to see if its on or not. And my temps are perfectly fine.

[humor]I'm not too sure about how quiet your system is. At our age, we don't hear alot of things.....[/humor]

You think so ? when my nephew works on his computer, I can hear more noise coming out of his headphones than any fan ever could.. I think my ears are still in better shape ;)

Know what you mean. I wish I couldn't hear the "music" from my sons headphones while in the car, wind noise and all.
