Arctic S4028-6K PC kastahoidla ventilator (ACFAN00185A)

The ARCTIC S4028-6K fan is a compact and efficient cooling solution designed for smaller computer cases and specific components that require additional airflow in a limited space. Its 4 cm size makes it suitable for server cases, industrial computers, mini-ITX systems or networking devices. This fan measures 40 x 40 x 28 mm, which indicates its compact nature, where "28mm" denotes an unusually large thickness compared to standard 40x10mm or 40x20mm fans. This increased thickness often allows the fan to generate higher static pressure and airflow at the same speed, thus providing more effective cooling in areas with limited air movement. The fan has a 6K model, which indicates the use of ball bearings. Ball bearings are known for their long service life and resistance to high temperatures, making them ideal for continuous operation (24/7) in servers and other critical systems. They may be a little louder than FDB (Fluid Dynamic Bearing) bearings, but offer excellent reliability. Typically, such fans are equipped with a 3 or 4-pin connector for connecting to the motherboard or controller fan header. The ARCTIC S4028-6K provides reliable and efficient cooling to maintain optimal temperatures in your small systems.
