This Frameless 12V DC Cooling Fan Module is a high-efficiency, lightweight thermal management solution designed specifically for targeted airflow in tight enclosures. Featuring a 5-blade semi-transparent rotor and a pre-wired 2-pin connector, this specialized brushless fan is a perfect direct replacement for worn-out cooling units inside IPS inverters, UPS backup systems, and custom electronic project boxes where standard square-framed fans will not fit.
