Description
Delta KSB0705HB-BB24 is a 5VDC 70x70x10mm Blower Fan optimized for thermal management in ultra-thin laptop chassis. This unit features a brushless DC motor with a dual ball bearing architecture, ensuring low thermal impedance and high structural rigidity under continuous operation. Designed with a 4-wire PWM interface, it allows for precise speed modulation to balance acoustic profiles with cooling demands. Operating at 0.40A with a power consumption of 2.0W, it effectively mitigates heat soak in high-density mobile computing environments. The aerodynamic impeller is engineered to maximize static pressure, crucial for pushing air through restrictive heat pipe fins in Asus N45 and N55 series notebooks.
