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."
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.
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.
This has me thinking. Sometimes I do that =)
:)
But seriously. Anyone seen sites with info on overclocking ancient CPUs? I remember once seeing a 486 overclocked well over 100MHz, perhaps into the 200MHz range, through refrigerated cooling. To me, that's as interesting as getting 5GHz from a brand new CPU.
Any 50MHz 68000s? A 300MHz Pentium I? 250MHz from a PPC601?
A 50MHz Commodore 64, even?
Now this is the ultimate cooling system... =)
The last part of the video (the flower thing) is even scary!
