Hey there, I just turned on my 2020 iMac, at my desk, the same way I have since I bought it and all of a sudden really loud fans came on. The computer isn't running any intensive programs or anything. What do I do?!

+1 Also when doing a SMC reset I have found it wise to disconnect any wired peripherals (printers, scanners, cameras, etc) and do the SMC reset 2-3 times as the first time does not always work.
