To address laptop fan noise issues, users can start by cleaning the fan and heat sink, which may require disassembling the laptop. Using compressed air can help, but thorough cleaning is often more effective. If the noise persists, it may indicate hardware failure, commonly seen in high-end gaming laptops like the Dell XPS and Alienware series. If the fan's ball bearings are worn out, replacement is usually necessary. For those uncomfortable with disassembly, seeking professional help is advisable to avoid potential damage or electric shock.
