To most enthusiasts, Arctic is best known for their Freezer line of CPU coolers as well as their thermal compound called MX-2 and MX-4. [2] The Freezer line of coolers is available in different fan speed, cooling capacity and motherboard compatibility [3] to cater the needs of different type of users from HTPC users to enthusiasts and overclockers.
An ultra low temperature (ULT) freezer is a refrigerator that stores contents at −80 to −86 °C (−112 to −123 °F). [1] An ultra low temperature freezer is commonly referred to as a "minus 80 freezer" or a "negative 80 freezer", referring to the most common temperature standard. [2] ULT freezers come in upright and chest freezer formats.
Inside the freezer, air is circulated by means of one or more fans. In a typical design cold air from the freezer compartment is ducted to the fresh food compartment and circulated back into the freezer compartment. Air circulation helps sublimate any ice or frost that may form on frozen items in the freezer compartment. While defrosting, this ...
Cooling capacity is the measure of a cooling system's ability to remove heat. [1] It is equivalent to the heat supplied to the evaporator/boiler part of the refrigeration cycle and may be called the "rate of refrigeration" or "refrigeration capacity".

Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).
Life in the Freezer is a BBC nature documentary series written and presented by David Attenborough, first transmitted in the United Kingdom from 18 November 1993. A study of the seasonal cycle of Antarctica , it was the first of Attenborough's more specialised surveys following his major trilogy that began with Life on Earth .
A map of the Arctic. The red line is the 10 °C isotherm in July, commonly used to define the Arctic region; also shown is the Arctic Circle. The white area shows the average minimum extent of sea ice in summer as of 1975. [1] The climate of the Arctic is characterized by long, cold winters
