1. A fan assembly comprising:
a first fan comprising a first housing and a first impeller positioned within the first housing, the first housing having a first plurality of fastener apertures formed in a first side of the first housing;
a second fan comprising a second housing and a second impeller positioned within the second housing, the second housing having a first plurality of fastener apertures formed in a first side of the second housing; and a first press fit stabilizer formed of a single piece of material of a substantially uniform thickness and comprising:
a main body portion; and
a plurality of press fit tabs Sort with respect to the main body portion to extend from the main body portion in a common direction, wherein the first fan is coupled to the second fan via:
a first press fit tab of the plurality of press fit tabs inserted into a first fastener aperture of the first plurality of fastener apertures of the first housing; and
a second press fit tab of the plurality of press fit tabs inserted into a first fastener aperture of the first plurality of fastener apertures of the second housing.
 
11. A method of coupling a fan assembly to an enclosure comprising:
positioning a first fan adjacently to a second fan, each of the first and second fans comprising a housing having a first plurality of fastener apertures formed in a first side thereof and a single impeller positioned within the housing, wherein a first upper fastener aperture of the housing of the first fan is adjacent to a first upper fastener aperture of the housing of the second fan, and wherein a first lower fastener aperture of the housing of the first fan is adjacent to a first lower fastener aperture of the second fan;
aligning a first press fit tab of a first press fit stabilizer with the first upper fastener aperture of the first fan;
aligning a second press fit tab of the first press fit stabilizer with the first upper fastener aperture of the second fan;
aligning a third press fit tab of the first press fit stabilizer with the first lower fastener aperture of the first fan;
aligning a fourth press fit tab of the first press fit stabilizer with the first lower fastener aperture of the second fan;
pressing the first, second, third, and fourth press fit tabs into a respective one of the first upper and lower fastener apertures of either the first fan or the second fan; and
coupling the housings of the first and second fans to a fan wall of the enclosure via coupling a respective fastener through the fan wall to each of a second upper fastener aperture of the first fan, a second upper fastener aperture of the second fan, a second lower fastener aperture of the first fan, and a second lower fastener aperture of the second fan.
