Designed for Continuous Operation
The S4028-15K is built for reliability under demanding conditions. Its impeller is supported by two premium Japanese dual ball bearings seated in a brass housing, ensuring strength, stability, and precise alignment. This design minimises the impact of dust and heat while significantly reducing wear at very high speeds, making it ideal for 24/7 continuous operation. The fan operates reliably in ambient temperatures of 0–40 °C and carries a six-year warranty for long-term dependability.
Full Control with a Wide Speed Range
With a speed range of 1400 to 15,000 rpm, the S4028-15K provides exceptional flexibility. Controlled via PWM or voltage, it can deliver quiet low-speed cooling when minimal airflow is required or ramp up to extreme performance for maximum cooling power. Despite its high speed, it maintains a balanced profile between cooling performance and noise.
High Airflow and Static Pressure
Compact in size at just 40 × 40 × 28 mm and weighing 42 g, this fan punches far above its weight. It delivers a maximum airflow of 19.23 CFM (32.67 m³/h) and a powerful static pressure of 26.5 mmH2O. This makes it highly effective for both radiator cooling and general case ventilation, particularly in high-density or high-heat environments.
Wide Range of Applications
The S4028-15K is purpose-built for 1U server cases but is equally suited to a wide array of hardware. It works as a replacement cooling solution for routers, switches, and NAS devices, and is also compatible with DVRs, mini PCs, HTPCs, external hard drive enclosures, and even 3D printers.
Flexible Connection Options
The fan comes with a standard 2510 4-pin PWM connector for precise speed control but is also compatible with 2-pin and 3-pin headers. Its 400 mm cable provides installation flexibility, making it easy to route within compact or complex builds. Power draw is modest at 0.47 A on 12 V DC, with a starting voltage of just 4.5 V.
