Ultimate Cooling System
OCGeek writes "This should be interesting for the overclockers as
VR-Zone has an article up on building a
cascade cooling system that
cools chips down to -110C. The guide shows you the components that are required
for the cascade cooling system such as the compressors, condensers,
refrigerants, evaporators, heat exchangers, oil separators etc. and the tools
you would need. It allows hot chip like Prescott to reach over 5.1Ghz and ATi
Radeon 9800 XT card to reach over 660Mhz core."
1. Because it's possible
2. It's kinda cool (literally0
3. It keeps overclockers off the streets
4. It gives us something to do
5. It's just interesting
6. Performance!
In a controlled situation, you wouldn't have any problems with condensation. I imagine when they turn the coolers off, they would want to bring the temperature back up to room temperature via a controlled sequence. You will get condensation if you go from that cold to warm rather quickly.

This seems a little complex and extreme for the home builder. Maybe a specialty co-lo opportunity, though? "Icebox netbox"? No good for gamers, of course. But for others who need MIPS for problems that can't be parallelized...
Everybody's a libertarian 'till their neighbour's becomes a crack house.

Sounds suspiciously like they stole the technology from Michael's computers...
Woohoo, that's hilarious. Awesome post my friend.
"...and I got my harddrives up to 21.2K rpms. You should hear her boot up, man... It's like something out of a freakin' movie... and I uped the voltage on the monitor, too. I gotta wear welder's glasses to freakin' check email, d00d... It's the best," said the greasy yongster between mouthfuls of pizza.
"Hey, did you up your typematic rate on the keyboard yet?" his friend asked excitedly. "One guy on the forums got his up to 1200 csp. That's uber as shit..." His words trailed off as the nubile 17 year-old waitress passed the geeks' table.
"..." remarked Pete, the greaser.
How do you overclock the user?
My hyperlinks aren't worth the paper they're printed on.
These techniques seem like brute force schemes to deal with the thermal resistance of chip packages -- you have to cool the heatsink to -110C in order to keep the "intel inside" at less than +60C). Why not use backside thinning. to bring the hot circuits of the processor within microns of a high coolant flux chamber. Backside thinning could get the coolant to within 10 microns of the junctions. If the CCD people can thin a massive 2k x 2k CCDs (the die is bigger than 1" square), I'm sure an enterprising overclocker could thin a Pentium.
Two wrongs don't make a right, but three lefts do.

Won't work in the summer, but you'll be too busy trying to scrape mosquitos out of your cooling fan to care.

I believe they attempt this in Florida and Texas a lot it involves something called "old sparky.
To date all overclocked users end up dead though.
I was a sysop for a BBS back in the dark ages before Internet, and one of users once asked me if it was possible to overclock a modem to get higher speeds. I promptly answered: "Do you have an external modem? Good, just replace your current transformer with something that gives you more volts for your modem." He thanked for advice and logged off.
He never called back.
Why yes, I do like reading BOFH stories, why do you ask?
