Abstract: The described embodiments relate generally to improving performance characteristics of a low profile fan. More specifically configurations having sloped fan blade edges are disclosed. By applying a gradual slope to each of the fan blades, performance of the fan can be increased without risking contact or rubbing between the fan blades and a fan housing. In some embodiments, the sloped fan blades can be configured to prevent contact when bearings of the fan include a certain amount of tilt play.

Abstract: The present application describes various embodiments regarding systems and methods for providing efficient heat rejection for a lightweight and durable compact computing system having a small form factor. The compact computing system can take the form of a desktop computer. The desktop computer can include a monolithic top case having an integrated support system formed therein, the integrated support system providing structural support that distributes applied loads through the top case preventing warping and bowing. A mixed flow fan is utilized to efficiently pull cooling air through the compact computing system.

Abstract: The described embodiments relate generally to control of rotational components in a computer system. In one embodiment, the rotational component includes a cooling fan assembly, the cooling fan assembly being controlled in accordance with resonant frequency avoidance data. The resonant frequency avoidance data being characteristic of the computer system such that when the cooling fan assembly operates in accordance with the resonant frequency avoidance data, the cooling fan assembly does not operate at a fan speed that is coincident with a natural resonant frequency of the computer system.

Abstract: The described embodiments relate generally to optimizing airflow in a computer system. By modifying the external surface of centrifugal cooling fan enclosures the pressure drop associated with airflow moving around the enclosures can be reduced. This is generally accomplished by rounding off hard edges from the outside of the cooling fan enclosure as well as forming cover surfaces rather than simply using flat cover surfaces. In some cases this can also involve modifying the shape of the fan inlet, or even contouring the shape of the cooling fan blades to allow air to flow more easily through the computer enclosure.
