iMac fans!

Hi,


The fans on my iMac seem to be on constantly and incredibly loud.

I don't really use it for any particularly intensive work (2D CAD package - not rendering images or anything like that, word, emails, general internet use etc), but the fans seem to be on almost permanently.

I've tried the classic turn it off and on again. I've tried disconnecting the power cable for 15secs, then what 5secs before turning power on. I've looked at the activity monitor and there is nothing that seems to operating at more than 6% CPU.

I'm by no means an IT-whizz - all of the above are answers I have googled - but there docent seem to be anyway to calm the fans down!


My iMac is :

iMac (Retina 5K, 27-inch, 2019)

3 GHz 6-Core Intel Core i5


Any suggestions would be very much appreciated!


Thanks,

Mark

Please reset the SMC 2-4 times back to back with ALL wired peripherals disconnected (printers, scanners, external HD's etc.) and then retest.


Please follow the instructions for a SMC reset in SMC Reset.
