I ran the extended Apple Hardware Test and got the error message: 4 MOT/4/40000002: HDD-0. What does that mean? What to do?
iMac 27″, macOS 10.13
4MOT = Fans, so your HDD isn't getting cooled it seems.
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.

Depends on the age of the Mac if they\re interested or not... older ones get no respect.
thanks for the suggestion. I talked to someone at Apple Support and she didn't mention that might be the problem. I gave her the MOT info, but she didn't seem interested.
Thanks for the help
