Notes: Blower-style fans provide higher static pressure for radiator and airflow-focused cooling but may generate slightly more noise than axial fans. Dual-ball bearing versions offer longer life at the cost of marginally higher noise. Current values on labels may be updated; contact seller for custom sizes or cable options.
