loud fan MacBook Air

"..You might need to reset the System Management Controller (SMC) on your Mac.."

Helps to correctly identify the build year model; if that is a newer M1, or Intel-mac, etc.

Usually section in Apple menu 'About this Mac' tells much about system configuration.

"loud fan MacBook Air: My fan comes on within a minute of starting up my MacBook Air. It did not used to do this. It is loud and annoying. What should I do to fix this. No, nothing is blocking the vents. It is on my desk and this is crazy."
