When the internal sensors detect temperatures climbing beyond a safe threshold, the fan ramps up to maximum speed to dissipate the heat. Hold the can upright to avoid moisture damage and do not use a vacuum cleaner, as the static electricity it generates can damage sensitive electronic components.
Effective Switch Fan Loud Ventilation Tips
A layer of dust on the fan blades increases the weight and imbalance, causing the fan to wobble slightly as it spins. Carefully use a can of compressed air to blow dust out of the vents on the top, bottom, and sides of the console.
While the Switch is designed to be used in various positions, placing it horizontally on a soft surface can seal the vents. Similarly, using the console in a room that is already warm can exacerbate the problem, as the ambient heat makes it more difficult for the internal fan to cool the components effectively.

For a deeper clean, you may need to open the console, but this should only be attempted if you are comfortable with electronics, as it will void your warranty. Regular cleaning of the external vents with compressed air can significantly reduce the amount of dust that enters the system, prolonging the quiet life of your hardware.
