Introduction
The increasing output of computer components such as CPU and graphics cards involve the need to increase the outputs of cooling devices, whose task is to remove the heat generated during the operation of the computational parts of the computer. The increase in the amount of the removed heat is associated with an increase in the size of the cooling units, whether it is water or air cooling. However, the expansion of cooling systems is limited by the size of the space defined by the outer casing of the computer. Current cooling units, primarily the water-cooling take up a significant space at the outer walls. Therefore, increasing the cooling efficiency of computational computer components is starting to come to the fore in connection with the effort to minimize space a modern computer should occupy and with miniaturization, lightening and at the same time increasing the output of portable computers. One of the biggest limitations of current laptops, which causes their lower output in comparison to desktop computers, is precisely their inability to cool the computational components as efficiently as in comparison to a desktop computer.
Conclusion
The article described the design of a system for the analysis of increasing the efficiency of CPU cooling using an air cooler. Calibration of the temperature sensors distributed within the aluminium block simulating the CPU was carried out. The calibration was also performed on the thermistors located between the ribs of the air cooler and at the inlet and outlet of the cooling air.
The basic calibration and creation of an initial comparison data package of the cooling power of the air cooler at different operating parameters will be described in the second part of this article.
