Claim 0:
1. A cooling system for an information handling system in a portable chassis comprising a bottom cover, a fan area proximate one or more of a heat pipe and a component, and a rear surface, the cooling system comprising:
a fan housing positioned in the fan area, the fan housing comprising:
a first side defining a fan housing width;
a second side defining a fan housing length less than the fan housing width;
an inlet proximate the bottom cover of the portable chassis; and
a fan outlet on a third side of the fan housing;

a first impeller positioned in the fan housing and configured to rotate in a first direction about a first axis of rotation;
a second impeller positioned in the fan housing and configured to rotate in a second direction opposite the first direction about a second axis of rotation; and
a controller operable to cause the first impeller to rotate at a first rotational speed and the second impeller to rotate at a second rotational speed, wherein:
the first impeller and the second impeller rotate to generate an airflow,
the axes of rotation of the first impeller and the second impeller are aligned with an axis of orientation that is non-parallel with the first side of the fan housing and the second side of the fan housing, wherein the axis of orientation forms a non-orthogonal angle with respect to the rear surface, wherein a magnitude of the non-orthogonal angle is based on a positioning of the heat pipe with respect to the component such that the airflow is directed to the heat pipe, and
wherein the fan housing has a shape configured to direct the airflow to the heat pipe.
