Heating issue on a new Acer laptop

I bought an Acer A515-45-R209 yesterday and while using it today, I noticed the fan kept turning on and made a lot of noise when i tried to use while it’s plugged in, the fan is pretty quiet when it’s not plugged into. For now, I’ve limited the power to the cpu to 80%, not sure if that affects performance but noise is not that bad compared to what is was earlier. Was wondering if this was normal or if I should maybe replace/return it.
