Введение
If your Dell Inspiron 1721 has a loud fan or is prone to overheating, use this guide to replace the internal fan.
Internal fans circulate cool air to a heat-sink, allowing the CPU to stay at a low temperature, even during stressful performance. Dusty internal fans will restrict airflow in any device.
Before using this guide, verify that the computer is completely shutdown.
