Precise temperature control: The fan can quickly cool the extruded material to prevent model deformation caused by heat accumulation (such as the warping problem of PLA) and the accuracy of details. Reduce drawing/drooping: Timely cooling can prevent material residue in non-printing areas and improve finish Heat barrier heat dissipation: The fan effectively cools the upper part of the hot end to prevent heat from moving up and causing the throat to soften, reducing material blockage (especially important for high-speed printing or high-temperature materials such as ABS) The low-noise fan design is suitable for home or office environments to reduce noise interference during long-term printing Supports a wide temperature range from PLA to engineering materials (such as nylon, PC), and the fan speed adjustment is flexible to adapt to the cooling needs of different materials The modular structure is easy to disassemble for cleaning or replacement, and some models support software-defined fan curves to meet the needs of advanced users Model:D2510B05H Size:25x25x10mm Voltage:DC5V current:0.4A power:2W Speed:15000+10%RPM Air volume:3.1CFM Terminal model:Integrated terminals Bearing:Double ball bearing temperature range:-10-80 (The product printed words depending on the batch, but this does not affect use) Color:As Shown Material:plastic Package Contents: 1 * Mini Fan Only the above package content, other products are not included.
