The Fluctus 120 PWM is a fan with an optional semi-passive mode. Although it stands only 12 cm tall, it could easily compete with larger opponents in a cooling performance duel. It would likely also win in the category of "practical size for almost any case." This device keeps a cool head when dealing not only with densely ribbed radiators in liquid cooling systems but also with cases that have dust filters. In any case, it offers high efficiency and excellent performance. Additionally, it is easy to install—even if you've never done it before. Just think of the envious looks from your friends when you show them your masterpiece.
