Inspecting and Preparing Fan Blades for Installation

What happens here

The host unveils one of the fan blades, pointing out its aerodynamic airfoil design, which resembles an airplane wing. Kevin elaborates that this shape is key to efficiently moving large volumes of air, especially at lower RPMs, which translates to more 'bite per watt' (greater air movement for less energy). The blades are constructed from aluminum extrusions, which arrive with natural marks from the manufacturing process. The next step will be to carefully install these blades onto the fan's central hub.

Goal: Examine the fan blades and understand their aerodynamic design.
