The fan assembly can include a first support frame. The fan assembly can comprise a shaft assembly having a first end coupled with the first support frame and a second end disposed away from the first end. A second support frame can be coupled with the first support frame and disposed at or over the second end of the shaft assembly. An impeller can have fan blades coupled with a hub, the hub being disposed over the shaft assembly for rotation between the first and second support frames about a longitudinal axis. Transverse loading on the shaft assembly can be controlled by the first and second support frames. ## Claims ### Claim 1 An electronic device comprising: a housing comprising: a first compartment in which a first electronic component is disposed; a second compartment in which a second electronic component is disposed, one or both of the first and second electrical components electrically communicating with another component of the electronic device; and a connection portion extending between the first and second compartments, wherein the first compartment is separated from the second compartment at a location spaced away from the connection portion by a gap to provide thermal separation between the first and second electronic components. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein the first electronic component comprises a processor. ### Claim 3 (depends on 1) The electronic device of claim 1, wherein the second electronic component comprises a power supply. ### Claim 4 (depends on 3) The electronic device of claim 3, wherein the power supply comprises a battery. ### Claim 5 (depends on 1) The electronic device of claim 1, wherein the first compartment, the second compartment, and the connection portion are filled with a gas. ### Claim 6 (depends on 1) The electronic device of claim 1, wherein the connection portion comprises a channel between the first and second compartments. ### Claim 7 (depends on 6) The electronic device of claim 6, wherein the channel has a side cross-sectional area that is smaller than a cross-sectional area of the first compartment taken along a direction parallel to a maximum dimension of the first compartment. ### Claim 8 (depends on 1) The electronic device of claim 1, wherein the electronic device comprises an augmented reality device. ### Claim 9 (depends on 8) The electronic device of claim 8, further comprising a connector configured to connect to a headpiece to be worn by a user. ### Claim 10 (depends on 1) The electronic device of claim 1, wherein the first electronic component electrically communicates with the second electronic component. ### Claim 11 (depends on 1) The electronic device of claim 1, further comprising a clip disposed in the gap between the first and second compartments. ### Claim 12 A portable electronic device comprising: a housing; a battery disposed in the housing, the battery supplying power for at least a portion of the portable electronic device; electronic components for operating the portable electronic device, the electronic components disposed in the housing; and a thermal mitigation assembly comprising a frame assembly, comprising: a shaft assembly having a first end and a second end opposite the first end, the first and second ends supported by the frame assembly; an impeller having fan blades coupled with a hub, the hub being coupled with the shaft assembly for rotation within the housing about a longitudinal axis of the shaft assembly; wherein loading transverse to the longitudinal axis of the shaft assembly is controlled by the frame assembly at the second end of the shaft assembly; and wherein the thermal mitigation assembly removes heat generated from one or both of the battery and the electronic components. ### Claim 13 (depends on 12) The power supply assembly of claim 12, wherein the housing comprises a first enclosure and a second enclosure, the electronic components and the thermal mitigation assembly disposed in the first enclosure and the battery disposed in the second enclosure. ### Claim 14 (depends on 12) The power supply assembly of claim 12, wherein the shaft assembly comprises a first shaft portion connected to a first frame of the frame assembly and a second shaft portion connected to a second frame of the frame assembly, the first and second shaft portions disposed at least partially on opposing sides of the hub.
