R40W12BGCA-65Z10 is a 40mm high-speed server cooling fan with PWM control, engineered as a replacement fan for NF 5170m3 and NF 5240m3 servers.
This server fan adopts PWM speed control technology, which dynamically adjusts fan speed based on the server internal temperature. It provides powerful high-speed airflow to exhaust accumulated heat inside the server chassis, protecting CPU, memory and other core components from thermal damage.
Built with durable bearing, this fan can run continuously 24 hours a day with stable rotation and low vibration. Accurate mounting hole layout and matching connector support direct installation without extra modification. Each fan passes strict rotation and PWM function testing before shipment for reliable server operation.
