The paper presents a review of the main types of cooling systems and the main methods of predicting their reliability characteristics. Creation of the technique allowing to consider features of indicators of reliability of the components of the cooling systems applied in computer equipment is considered. With the help of the technique it is possible to calculate in addition to the electronic component, also the mechanical part of the cooling system, which distinguishes it from the standard methods of reliability assessment. This allows us to give an updated value of reliability. Standard computational models of failure rates are analyzed and supplemented with a number of correction factors that are absent in them. The resulting technique is applicable at various stages of design and creation of systems and computer facilities, as well as in conditions where there is a minimum amount of data on the created equipment.
