Introduction
This guide shows you how to replace the cooling fan in an HP Pavilion 17-g192dx laptop.
Cooling fans help keep devices cool, as the name implies, by circulating air to dissipate excess heat. However, cooling fans have an average lifespan of only 3-6 years, and that lifespan can be further shortened by a dusty environment. An old or damaged laptop cooling fan can cause serious issues, from lagging to system crashes to device damage. If you notice grinding noises coming from your laptop, a hotter-than-usual CPU temperature, and/or decreases in system performance, it may be time to replace your cooling fan.
This replacement is relatively fast and easy, though it does require knowledge of How to Apply Thermal Paste. This is because the cooling fan is located on the motherboard and is connected to the heat sink; any time you remove a laptop's heat sink, you must reapply thermal paste during reassembly.
Lastly, ensure your laptop is powered down and unplugged from the charging adapter before you begin the repair.
