We review a lot of fans and other computer cooling equipment here at OCModShop. In some ways, testing fans are quite straightforward, and in other ways they are very subjective. The noise and airflow ratio produced by any given fan changes as the blades and motor gather dust. Debris on the blades can actually chip away at the blade edge over time, making it less aerodynamic, which reduces airflow and increases noise. Dust in the motor means friction, which requires more electricity to move the fan around and increased noise.
