Maxwell - Re: "Kryotech is the only company that makes such device to cool down the CPU. It was used to demo a 0.35um PII running at 400MHz."
WRONG !
AGAIN !
Intel used a recirculating, refrigerated ice-water bath - to cool the 0.35 micron KLAMATH - not a KRYOTECH cryogenic device.
And the Klamath ran at 433 Mhz during that demo.
You play fast and loose with the facts - maybe that explains why the yield problems in MegaFlop 25 lasted so long.

Intel makes it a race with 451MHz
Klamath processor

SAN FRANCISCO -- While the microprocessor horsepower race still goes to
Digital's Alpha architecture at 600 MHz, Intel on Friday surprised attendees at the International Solid State Circuits Conference here by disclosing that it has pushed the P6 Pentium Pro architecture to as fast as 451 MHz.
Scheduled to present a paper on a 300-MHz Klamath processor, Mustafiz R. Choudhury, design manager at Intel's Microprocessor Products group, in Santa Clara, Calif., instead disclosed that the processor is running at 433 MHz. And, he said, Intel researchers have seen 451-MHz operation in the laboratory.
Choudhury called the device "the highest performance Intel Architecture-compatible microprocessor." The 7.5 million-transistor processor offers a projected performance of about 12 SPECint95 in its 300-MHz version, he said.
However, Choudhury stressed that the processor is a technology disclosure and not an available product. The device's power dissipation bears this out. While he would not say how much power the chip dissipates, Choudhury admitted that it requires an
ice-water heat sink to maintain an operational temperature.
A system based on the device and running at 400 MHz was demonstrated for the press after Choudhury's presentation, and this computer required a cooling system hidden under the table.
