Computer system including a computer housing with a fastening device

A computer system comprising:

• a computer housing with a fastening device that fastens the computer housing to a mount;
• a system board arranged in the computer housing and having at least one component to be cooled;
• an axial fan that cools the at least one component arranged in the computer housing in a region of the at least one component;
• a first ventilation area arranged laterally next to the fastening device in a first housing wall of the computer housing;
• and
• a ventilation channel extending in the computer housing between the first ventilation area and the axial fan, which is fluidically separated from the rest of the computer housing;
• wherein the axial fan is arranged in the computer housing such that an axis of rotation extends substantially perpendicular to an extension plane of the system board and an extension direction of the ventilation channel substantially parallel to the system board, and
• wherein the ventilation channel has a first inner width in the direction of the axis of rotation, a second inner width perpendicular to the extension direction of the ventilation channel, and the first inner width is smaller than the second inner width by at least one order of magnitude.

An all-in-one computer system, comprising

• a computer housing;
• a system board arranged in the computer housing and having at least one processor to be cooled;
• a heat sink arranged directly on the processor;
• a display screen arranged at a housing front wall of the computer housing facing a user;
• a fastening device that fastens the computer housing to a display mount, the fastening device arranged at a rear wall of the computer housing opposite the housing front wall;
• an axial fan that cools the at least one processor by accelerating air in the direction of the heat sink or away from it, the axial fan being arranged on the heat sink of the processor in a region of the fastening device;
• a first ventilation area arranged laterally next to the fastening device in the rear wall of the computer housing;
• and
• a ventilation channel extending in the computer housing between the first ventilation area and the axial fan, which is fluidically separated from the rest of the computer housing.
