Features: Features double sided drive powerful fans, delivering significantly increased airflows compared to original unit to create an efficient directional airflows channel. Innovatively employs an integrated high-thermal-conductivity aluminium alloy base, functioning directly as a massive heat dissipation. Exclusively moulded for precise positioning; customized engineered with all openings (screw holes, ports, ventilation slots) precisely matching original device. Installation is straightforward,not requiring modifications. It fits perfectly, providing comprehensive protections while avoiding installation issues caused by dimensional mismatches. Scientific airflows and dust-proof design achieve both stability and quiet operating：Optimised internal airflows structure reduces air resistance, enhancing cooling efficiency while effectively controlling noise. The metal base furthered strengthens the overall structural integrity, offering a more secured grip and comprehensively improving the user experience.
