2Pcs 3D Printer Cooling Fan, 5V 4010 8000RPM SM Positive Terminal, 40X40X10Mm

What is it?A 3D printer cooling fan is a component designed to regulate temperature during printing. It is compatible with most motherboards and is a good replacement for noisy or damaged fans in 3D printers, CPU coolers, graphics cards, NAS, hard drives, switches, and other network and storage devices.What will I get?Color: BlackMaterial: PlasticSize: 40x40x10 mm / 1.57x1.57x0.39 inch (L x W x H)Mounting Hole Distance: 32.2mm / 1.27 inchHole Diameter: 3.7/6.2mm / 0.15/0.24 inchTerminal: SM Positive TerminalRated Voltage: 5VFan Speed: 8000RPMFan Blades: 9 BladesWire Length: 30cm / 11.81 inchBearing: Hydraulic BearingIn the package of: 2 Pcs x 3D Printer Cooling FanAre there any advantages of this product?This 3D printer cooling fan features a hydraulic bearing design that forms a sealed oil seal, resulting in lower wear and longer-term stable performance. It guides airflow to rapidly cool the extruded molten filament, allowing layers to solidify quickly, preventing warping, improving sag/bridging, and ensuring dimensional accuracy. The blades concentrate the airflow for efficient heat dissipation from the hot end, extruder, and other critical components.How to use it?This 3D printer fan is easy to install. Locate the correct fan connector on the motherboard. Ensure the voltage and polarity match, then securely connect the connector. Align the fan with the mounting point and tighten it with screws.What should I notice?Before purchasing our products, please confirm the product specifications to ensure that it is suitable for your device.
