Ceramic Bearing Design: Our WK-A360 aio cooler employs ceramic bearings that do not chemically react with coolant, ensuring pump durability and silence, free from rust and corrosion issues commonly found in metal bearings. Additionally, the integration of a 3-phase motor minimizes pump noise, providing a serene and efficient computing environment Dual Chamber Pump: The AsiaHorse 360mm aio boasts an advanced dual-pump system. The internal water-cooled base pump rotates at 3000 RPM, while the inter-tube pump is 4500 RPM and enhances flow rate by up to 30%, reaching an impressive 300L/H, ensuring efficient heat dissipation Silent and Efficient Fan System: The liquid cpu cooler is equipped with three 120MM large-diameter blade fans, generating a noise level as low as 21-33 DBA, ensuring tranquility even at full speed. With an airflow rate of up to 65CFM, it reliably dissipates heat and maintains the efficient operation of your computer system
