Over time, laptop cooling fans can wear out, become noisy, or stop spinning altogether — leading to reduced airflow and thermal throttling of your CPU and GPU. Swapping in a quality replacement fan is one of the most effective ways to restore your laptop's full performance capability and extend its operational life.
