The Lenovo cooling fan and heatsink FAN+Heatsink SWG Delt (01AY474) is a cooling component for Lenovo computer systems. This assembly combines a heatsink and fan unit for efficient heat regulation of processors and other heat-generating components. The heatsink is made of aluminum with precision-engineered fins that maximize the surface area for optimal heat dissipation. The integrated fan utilizes a ball bearing design for reliable operation and consistent airflow. This cooling solution maintains stable operating temperatures, prevents thermal throttling, and extends the lifespan of components. The unit measures approximately 80 mm in diameter with a standard thickness of 25 mm and is compatible with various Lenovo desktop and workstation configurations. The fan reaches speeds of up to 2500 RPM while producing noise levels below 30 dB for quiet operation. With a maximum airflow capacity of 45 CFM, this cooling assembly handles thermal loads in demanding computing environments. The mounting system uses standard screw fasteners for secure installation and proper pressure between the heatsink base and the processor. Integrated copper heat pipes in the heatsink enhance thermal conductivity for rapid heat transfer from the source to the cooling fins. The component is maintenance-friendly with a dust-resistant design that preserves performance over extended periods. The product meets industry standards for reliability and thermal performance in computer cooling applications.
