04520GA12NAU is a 4520 miniature centrifugal turbine blower fan specially used for projector cooling. Powered by DC12V, this dualballbearing blower fan is equipped with 4pin PWM tachometer cable, enabling motherboard to dynamically adjust fan speed according to internal temperature and read realtime rotationalspeed signal. High staticpressure blower airflow penetrates narrow internal channels of projector, effectively carrying away heat generated by light source, color wheel and mainboard, preventing projector overheating shutdown, screen dimming and hardware premature aging. Adopting premium dual ball bearing, it maintains stable performance under longtime continuous hightemperature operation. Standard dimension and mounting positions support convenient replacement for original projector blower fan. Besides projector repairing, it is also suitable for other smallsize electronic hardware needing highstaticpressure ventilation. Please verify dimension, rated voltage and pin definition before purchase for proper compatibility.
