Best Sleeve Case Fans in 2025

OPTIMISED FOR STATIC PRESSURE: During the development of the new P12 PWM PST, special emphasis was placed on a focused airstream and thus a high static pressure

200 TO 1800 RPM REGULATED VIA PWM PST: Thanks to 4-pin connector, the RPM can be regulated in a broad spectrum via PWM, noise is kept at minimum while maximum cooling performance is given when needed

MORE EFFICIENT TECHNOLOGY: The motor is powered by a Neodym-Iron-Boron-Magnet ring of the newest generation, which allows the new P12 PWM PST to run much more efficiently than its predecessors

OPTIMISED FOR STATIC PRESSURE: The fan guarantees extremely efficient cooling, even with increased air resistance, therefore, the P14 is particularly suitable for use on heatsinks and radiators

HIGH QUALITY BEARING: Thanks to an alloy/lubricant combination developed in Germany, friction within the bearing is reduced and greater efficiency is achieved

INNOVATIVE DESIGN: The innovative design of the fan blades improves the air flow and facilitates a highly efficient ventilation, the impeller was designed with a focus on minimzing the noise level

INNOVATIVE DESIGN: Design of fan blades improves airflow and facilitates efficient ventilation, impeller was designed with a focus on minimzing the noise level yet delivering the desired airflow and pressure

PERFECT CASE FAN REGULATION WITH PWM: The PWM function allows the motherboard to run the fan precisely at its necessary speed, this guarantees the required cooling and minimizes the noise level

PWM SHARING TECHNOLOGY (PST): PST assures that all of your fans listen to one control signal, e.g. you share the CPU Cooler's PWM signal and assure that your case fans stand down at low load and spin up whenever necessary
