2. Computer cooling - Wikipedia

   en.wikipedia.org/wiki/Computer_cooling

   Liquid cooling is typically combined with air cooling, using liquid cooling for the hottest components, such as CPUs or GPUs, while retaining the simpler and cheaper air cooling for less demanding components. The IBM Aquasar system uses hot water cooling to achieve energy efficiency, the water being used to heat buildings as well. [40] [41]

3. Liquid nitrogen - Wikipedia

   en.wikipedia.org/wiki/Liquid_nitrogen

   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.

4. ETA10 - Wikipedia

   en.wikipedia.org/wiki/ETA10

   Although such cooling could potentially speed up the CMOS logic by a factor of four, in practice the liquid nitrogen cooling yielded an approximately twofold speed increase over air-cooled systems. However, because liquid nitrogen cooling yielded only marginal performance benefits, none of the ETA10 systems used such cooling for either the ...

5. Aquasar - Wikipedia

   en.wikipedia.org/wiki/Aquasar

   The Aquasar contains water-cooled IBM BladeCenter Servers (IBM's versions of the bare-bones server computer) and air-cooled IBM BladeCenter Servers in order to contrast the performance of the hot-water coolant and the air cooling. The air-cooled and water-cooled BladeCenters are made up of IBM BladeCenter H Chassis, using a combination of IBM ...

6. Cray-2 - Wikipedia

   en.wikipedia.org/wiki/Cray-2

   Due to the use of liquid cooling, the Cray-2 was given the nickname "Bubbles", and common jokes around the computer made reference to this unique system. Gags included "No Fishing" signs, cardboard depictions of the Loch Ness Monster rising out of the heat exchanger tank, plastic fish inside the exchanger, etc. The power consumption of the Cray ...

7. Liquid cooling - Wikipedia

   en.wikipedia.org/wiki/Liquid_cooling

   Liquid Cooling Garments (LCG) are used to decrease the wearer’s bodily temperature and keep them comfortable. Generally, an LCG uses a series of coolant-filled tubes and a refrigeration unit and a pump to move the coolant throughout the system.

8. Immersion cooling - Wikipedia

   en.wikipedia.org/wiki/Immersion_cooling

   These systems are replaced with liquid circulation pumps and heat exchanger and/or dry cooler systems. Power use at data centers is often measured in terms of power usage effectiveness (PUE). The definitions of PUE for air-cooled devices and liquid immersion cooled devices are different which makes such direct comparisons inaccurate.

9. Cryocooler - Wikipedia

   en.wikipedia.org/wiki/Cryocooler

   After the JT expansion, point d, it has a temperature of 77.36 K (−195.79 °C; −320.42 °F) and a pressure of 1 bar. The liquid fraction is x. The liquid leaves the system at the bottom of the reservoir (point e) and the gas (fraction 1 − x) flows into the cold (low-pressure) side of the counterflow heat exchanger (point f). It leaves the ...
