Among these was the use of liquid nitrogen for cooling the CMOS-based CPUs. The ETA10 successfully met the company's initial goals (10 GFLOPS), with some models achieving a cycle time of about 7 ns (143 MHz) - considered rapid by mid-1980s standards. They delivered seven liquid nitrogen-cooled versions and 27 smaller, air-cooled versions.
In a typical installation of liquid nitrogen cooling, a copper or aluminium pipe is mounted on top of the processor or graphics card. After the system has been heavily insulated against condensation, the liquid nitrogen is poured into the pipe, resulting in temperatures well below −100 °C (−148 °F).
Liquid nitrogen may be used for cooling an overclocked computer, when an extreme measure of cooling is needed. Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization.
Contemporary cryogenic processors monitor temperature fluctuations and modulate the liquid nitrogen input to ensure that only fractional changes in temperature occur over a specific period of time. These temperature readings and adjustments are synthesized into profiles that are used to repeat the process when treating similarly grouped objects.
A computer fan is any fan inside, or attached to, a computer case used for active cooling. Fans are used to draw cooler air into the case from the outside, expel warm air from inside and move air across a heat sink to cool a particular component. Both axial and sometimes centrifugal (blower/squirrel-cage) fans are used in computers.
The Aquasar supercomputer employs "on-chip" cooling. [4] It uses a unique method that uses micro-channel coolers which are directly attached to the computer's processing units (the main circuits that perform most of the computer's processing) which produce some of the most heat in the computer system.

An intermediate shield between the outer and inner vessels intercepts the heat radiated from the outer vessel. This heat is removed by a cryocooler. Older helium cryostats used a liquid nitrogen vessel as this radiation shield and had the liquid helium in an inner, third, vessel. Nowadays few units using multiple cryogens are made with the ...
The heated liquid was cooled using chilled water heat exchangers and returned to the main tank. Work on the new design started in earnest in 1982, several years after the original start date. While this was going on the Cray X-MP was being developed under the direction of Steve Chen at Cray headquarters, and looked like it would give the Cray-2 ...
