2012 Mac mini with 2.3 GHz i7, 16 gb RAM and SSD runs hot with fans almost constantly on

I've installed Sequoia 15.4 on my Mac mini late 2012 and I found it runs quite hot with fans spinning up when I'm opening a new webpage (Safari) or an app (like Signal). Is it an expected behavior considering the age of the hardware? I am okay with it as long as it is normal!
