Anycubic Mainboard Cooling Fan For Kobra S1

Description The Kobra S1 Mainboard Cooling Fan is a specialized DC brushless axial fan tasked with driving constant thermal dissipation inside the printer's lower electronics bay. 3D printer motherboards run warm because their integrated stepper motor drivers dynamically shift high levels of electrical current to handle rapid CoreXY or high-acceleration Bed Slinger movements. This fan mounts directly onto or adjacent to the motherboard chassis cage, forcing high-volume airflow across the driver heatsinks and power MOSFETs. Over thousands of operational hours, cooling fans can collect fine plastic dust or suffer bearing fatigue, leading to grinding noises, slow rotation speeds, or complete failure. Replacing a degrading fan immediately resolves electronic thermal throttling, preventing unexpected printer shutdowns, layer shifts, or catastrophic driver burnouts. Features High-Efficiency Airflow Delivery: Designed with an optimized blade geometry that delivers maximum volumetric airflow (CFM) at low static pressures to sweep heat completely away from sensitive logic gates. Whisper-Quiet Brushless Core: Utilizes a premium brushless motor array to drastically cut down on electrical switching noise and hum, keeping the printer quiet during overnight jobs. Wear-Resistant Sleeve/Hydraulic Bearing: Equipped with a dust-shielded bearing array optimized for horizontal mounting positions, ensuring reliable operation without leaking internal lubricant. Low-Amperage Draw: Engineered to run efficiently on the motherboard’s dedicated cooling rails, leaving plenty of power for the hotend heaters and stepper drivers.
