If the fans in your device run fast even when it isn't experiencing heavy usage and is properly ventilated, follow the steps for your device:

On an Intel-based Mac: Reset the System Management Controller (SMC)
On a Mac computer with Apple silicon: Close and open the lid on your laptop, or restart your computer.
