set includes two EFB0412LD 4020 axial cooling fans. Each fan measures 40×40×20mm, runs on DC12V and draws 0.08A, built with dual ball bearings for reliable long-term operation. The compact 4cm footprint fits inside tight spaces such as switch cases, power supplies, small adapters and network hardware. It continuously expels heat from power components and circuit boards to prevent overheating, thermal shutdown and premature hardware failure. Dual ball bearing structure improves durability and vibration tolerance, suitable for 24-hour continuous running. The aerodynamic fan blades maintain steady airflow while keeping noise at a low level. Standard mounting hole layout matches original fan specifications, no drilling or modification needed during installation. Every fan passes strict testing for rotational speed, noise level and electrical continuity before packing. It serves as a cost-effective drop-in replacement for worn, seized or noisy original fans in power supplies and small network equipment.
