I have a 2011 iMac, running High Sierra. (I know, this is old!)
Beginning yesterday, there is a very loud and constant fan/blower noise.
I don't what do with this or if I should be concerned.

Don't slow the fan down...
Have you blown the dust out of the intakes lately?
What temperatures does this App report? Especially the GPU.
This App can be used to speed up the fans, all my iMacs would be dead without it.
Never ever ever drop fan speeds below the speed that the Mac itself is calling for.

Thank you for your help. I ended up turning off the computer for awhile, and when I turned it back on, the fan had stopped blowing. I am going to look into your other suggestions this weekend.
OK, take care my friend.
