    DS04020B12U axial cooling fan is reliable replacement spare part for CPU and computer chassis hardware. Measuring 40x40x20mm (40mm / 4cm /4020), it operates at DC 12V 0.25A with 4Pin PWM interface, allowing realtime speed adjustment controlled by the motherboard. Dual ball bearing design lowers mechanical wear, ensuring stable performance under longtime running conditions. It provides sufficient airflow to expel internal heat and prevent hardware thermal throttling. When your original fan produces abnormal rattling noise, spins slowly or stops working, this fan offers costeffective repair solution. Please verify fan model, dimension, voltage and pin definition before purchase. Mounting screws are not included.
