Computer case providing multiple independent airflows

A computer case providing multiple independent airflows, comprising:

• a case body hollowed to form an installation space which includes a logic process zone, a magnetic disk zone abutting the logic process zone and a spaced zone located between the logic process zone and the magnetic disk zone, and also includes a flow guide passage located in the spaced zone to allow external air to enter the installation space;
• at least one first air fan located in the installation space at one side of the logic process zone abutting the spaced zone to receive electric power to be activated to provide a first airflow to the logic process zone, the first airflow including a first air intake end to draw the external air from the flow guide passage and a first air discharge end at another side of the logic process zone remote from the spaced zone to discharge the external air from the installation space;
• and
• a second air fan located in the installation space at one side of the magnetic disk zone to receive electric power to be activated to provide a second airflow to the magnetic disk zone, the second airflow being not interfering with the first airflow and including a second air intake end and a second air discharge end at two sides of the magnetic disk zone.
