Zalman ZM is a series of computer case fans designed for users who value efficient cooling and low noise levels. These fans are equally suitable for overclocking or gaming PCs, as well as for professional workstations, where it is important to maintain optimal component temperatures without unnecessary noise. They are also ideal for users who plan to build a quiet or completely silent PC. The laws of physics have not yet been repealed, so 3 coolers at medium power will make much less noise than one fan operating at maximum power.


Physical specifications for Zalman ZM fans include 120mm and 140mm sizes, making them compatible with most standard computer cases. Despite the affordable price, all models in this series are of high quality and are based on durable hydrodynamic bearings, but PWM speed control depends on the model. Old turntables like the ZM-F3 operate at a fixed speed (1200, 1500 or 1800 rpm), while more modern models like the ZM-AF120 can automatically adjust their speed depending on the heating of the components.

Some models like the ZM-AF120 feature addressable RGB lighting, allowing the user to customize the appearance of their system to suit their preferences. The backlight is generally universal and supports all popular lighting control systems, including Asus Aura Sync, Gigabyte RGB Fusion, MSI Mystic Light and ASRock Polychrome Sync. However, backlit models are much less common here than in Aerocool, Be Quiet, Thermaltake and other competitors.
