The fan running is a good thing because it's stopping your Mac from overheating, which is a bad thing. You could lower your in-game graphics options so the game is demanding less from your GPU and processor. If it carries on it may be worth getting Apple to have a look at it when their stores reopen.

Thank you again for your response. I won't have time to play again until next week, but when I do I'll mess around with the graphics settings and see if I can get the fan to stop coming on. I'll reply here again next week and report any progress (or lack thereof). Also, good idea to go to the Apple store. If they were open, I'd go tomorrow and figure this out. But in the meantime I'll just see what changing the settings will do.

No, you NEED the fan to come on. If your fans don't run then your Mac will overheat and die eventually as the hardware will be damaged. What you need to do is try and figure out why the fan is ramping up so much and changing the settings may help - https://bjango.com/mac/istatmenus/. There is a great app here that will tell you the fan rpm. You can also see the temperature of various components.
But, you shouldn't have to lower settings, your Mac should be able to handle the game easily. I found this by simple Googling - https://forums.macrumors.com/threads/imac-2019-problems.2203816/, it wouldn't hurt for you to do a little research with "iMac Radeon Pro Vega 48 overheating" and see what you can find.
