A Typically, a PC usually relies on heat sinks and active cooling by forced airflow (ie i.e., fans) to remove heat from hot components. As the case becomes smaller shrinks so does the fansize. As a fan becomes A smaller it fan needs to rotate faster to achieve the same airflow. Faster rotation results in a higher noise level and a higher wearing rate. Small cases has have correspondingly small air inlets vents that clog quickly and decrease airflow efficiency which require , requiring the fan to rotate even faster increasing noise, wearing wear and the clogging rate further. Therefore This cycle cannot continue forever, therefore small PCs that rely PC's relying on fans for cooling are prone to overheating.
== Passive Cooling and fit-PC2 ==
Passive cooling by conduction is silent and has no avoids moving parts that can fail, making it far more reliable than active cooling. It Unfortunately it is also less efficient than active cooling. The accomplishment in fit-PC2 is bringing the 's system power consumption to such a is low level as enough to make accomplish passive cooling in a small case possible.<br> == So why is fit-PC2 case warm to the touch? ==fit-PC2's exterior feels warm because the case itself provides heat dissipation. You feel all the heat the system generates. Thermal performance is guaranteed to remain constant.
