This brand-new replacement cooling fan is exclusively tailored for ThundeRobot 911 Pro gaming laptops, compatible with all 15-W9, 15-XA, 15-SA, 15-WA variants. It adopts original factory dimension molding, consistent with the built-in fans outline, screw hole position and wiring layout.
Running on DC 12V power with 4-pin PWM connector, it supports automatic speed adjustment controlled by the laptop system. Optimized curved fan blades deliver strong heat exhaust airflow, effectively lowering CPU and GPU temperatures during long-hour gaming, video rendering and heavy multitasking to prevent performance drop and automatic overheat shutdown.
Equipped with high wear-resistant silent bearing, the fan operates with low vibration and less abnormal noise, extending service life under continuous high-load operation. Simple disassembly and plug-in wiring design greatly simplifies maintenance work for repair stores and personal DIY upgrades. Ideal spare cooling part to fix noisy, stuck or damaged original laptop fans.
