Loud Fan Noise

I bought my MacBook Air last month and it recently started to make very loud fan noises after 10 minutes of use. I tried to reset the SMC but it did not work. Is there any way to fix it?

MacBook Air 13″, macOS 10.15

The fans will speed up under heavy CPU load, that’s normal. I hear the fans in my kids’ MacBook Airs when they’re gaming.

Check Applications > Utilities > Activity Monitor to see if any apps are using substantial CPU capacity.
