What type of connectors are labeled sys_fan or pump_fan used for?

The connectors labeled sys_fan or pump_fan are specifically designed for powering case fans or cooling pumps within a computer system. These connectors provide a reliable source of 12V power, which is necessary for both fans that facilitate airflow in the case and cooling pumps that may be used in liquid cooling systems.

The sys_fan connector typically connects to fan units installed in the case to ensure proper ventilation, helping to maintain optimal operating temperatures for the components. The pump_fan connector serves a similar purpose but is explicitly meant for connecting the pumps used in liquid cooling setups, which require consistent power to function effectively.

This function is distinct from connections such as USB header ports, which are used for connecting USB devices, or audio header ports, which connect audio inputs and outputs. Other options involve different functionalities entirely, emphasizing the unique purpose of the sys_fan and pump_fan connectors dedicated to cooling solutions.
