If you dig down through the links in About fans and fan noise in your Apple product - Apple Support, you will eventually find this passage from Keep your Mac laptop within acceptable operating temperatures - Apple Support:
"If your Mac laptop gets warm even when it isn’t doing tasks that require intensive calculations, or if it has fans that run for a long time, use Activity Monitor to check CPU activity. Look for malfunctioning processes that can put a significant load on the CPU and check for unexpected fan use. If issues persist, close and open the lid on your laptop, or restart your computer. ..."
Post a screenshot of Activity Monitor if you wish. Use the Energy pane, or CPU sorted by %CPU to see which apps or processes are using the most energy or placing the greatest demands on your Mac's CPU, respectively. To show the most relevant information I suggest selecting "Active Processes" from Activity Monitor's View menu.
Google Chrome and all its constantly running information-harvesting "helper" processes are a notorious resource hog. There is absolutely no reason to use Chrome on a Mac. If you are required to use Google products get a Chromebook. Installing Google obviates most of the advantages of using a Mac.
