Corsair RS140 | 140mm | PWM | 1700 RPM

Overview

The Corsair RS140 is engineered for users who demand uncompromising thermal performance without sacrificing acoustic balance. As a high-performance 140mm cooling fan, it utilizes a sophisticated PWM-controlled motor that allows for a wide rotational range, scaling from a near-silent 330 RPM for idle tasks up to a powerful 1700 RPM for intensive gaming sessions or heavy rendering workloads. Its robust design ensures that your internal components receive consistent, high-volume airflow, effectively mitigating heat soak in even the most compact or densely populated computer cases.

Built with premium materials and precision engineering, the RS140 is designed to withstand years of continuous operation. The fan’s geometry is optimized to provide a maximum airflow of 95.5 CFM, while maintaining an impressive air pressure of 3.46 mmH2O. This makes it an ideal choice for both intake and exhaust configurations, ensuring that your system maintains a healthy thermal equilibrium. With a verified 5-Year Warranty, Corsair provides the assurance that this cooling solution is built for longevity and reliability.
