    compact 40x40x20mm highairflow axial cooling fan is a precise substitute for DS04020B12U, specially engineered for NVIDIA Jetson Nano embedded development board cooling. It operates at DC 12V with 0.25A rated current and adopts standard 4wire PWM wiring with tachometer signal output, enabling automatic fan speed regulation according to chip temperature. Dual ball bearing construction reduces internal abrasion and maintains steady rotation under longtime running AI computing workloads. Powerful airflow efficiently carries away heat generated by main processor modules, preventing thermal throttling and system overheating failures. Please verify dimension, operating voltage and pin definition before purchase. Mounting screws are not included.
