Laptop fans can be replaced, but it is not a simple process. Before attempting to replace a laptop fan, it is important to ensure that the fan is the source of any issues. Overheating laptops can be caused by blocked vents, which can be resolved by ensuring the laptop is well-ventilated and using compressed air to remove dust and dirt. If the fan is faulty, it may be possible to resolve the issue by cleaning the fan blades and re-lubricating them, or by replacing the thermal paste. If these steps do not work, it may be necessary to replace the fan. This can be challenging due to the specific shape and size of the fan, as well as the placement of wires. It is important to follow proper safety procedures to avoid causing further damage to the laptop.

Cleaning the fan
To clean the fan of your laptop, you should first power off and unplug your laptop. Compressed air can be sprayed into the vents in short bursts to loosen and remove any dirt, dust, or pet fur. If your laptop is extra dirty, spray air through the vents on the sides of the laptop to help release trapped dust and push air through the intake vents. If the fans need more cleaning, you can remove the battery and bottom panel.
If you are comfortable, you can remove the fan from the laptop using a screwdriver to wipe it down entirely. Compressed air can be used at this stage to spray small bursts into the fan and its attaching parts. You can also use a laptop cleaning brush to clean the nooks and crannies of the fan. Carefully slide the brush along the blades of the fan and underneath the protective plate. If there is something stuck to the blades, brushing is probably the best option to remove it.
You can also wipe the fan with a dry, lint-free cloth to remove any visible dust. If you are comfortable, you can disassemble the fan itself by unscrewing the protective plates to release the blade. You can also use a needle with some mineral oil on it to lubricate the hole where the spindle/shaft is inserted.
Additionally, you can clean the fan blades using an isopropyl (rubbing) alcohol solution and then re-lubricate them using a needle-tip precision lubricator. The motor itself can be lubricated using a Q-tip or other small object to get the lubricant into the slot the blades fit into.
