MacBook Pro 16" (A2485, A2991) Right Fan

An aging fan may become noisy and inefficient or simply fail and stop spinning, leaving your laptop to overheat and eventually damaging your processors. Replace a defective left fan to fix overheating problems or to keep your model A2485 or A2991 16" MacBook Pro running quietly. If your screen is facing you, this is the fan on the right side of the machine.
