AVC DA07520B12U 7520 75x75x20mm DC12V 0.52A 4Wire PWM TemperatureControlled Cooling Fan, Dual Ball Bearing Replacement Fan for Computer CPU & System Heat Dissipation

AVC DA07520B12U is a 75×75×20 mm axial DC cooling fan rated DC12V, 0.52A, designed for computer CPU and system thermal management. It adopts professional 4wire PWM control interface, which enables motherboarddriven temperaturelinked speed regulation, adjusting fan RPM dynamically according to internal component temperature to balance cooling performance and noise output. Builtin dual ball bearing structure greatly lowers mechanical friction, supports longtime nonstop operation and delivers superior durability compared to sleevetype fans. Optimized fanblade geometry delivers strong stable airflow to quickly exhaust accumulated heat inside devices. Standard mounting hole positions allow simple direct installation for fan replacement and equipment refurbishment. It is widely applied as replacement cooling unit for desktop CPU coolers, small chassis, industrial host and embedded hardware. This fan is perfect for PC maintenance, hardware repair projects and batch wholesale replacement demands, offering stable consistent thermal performance under longterm working conditions.
