    There is a problem with the fans on the iMac (2012's and on) once a HDD is replaced with a non 'Apple' HDD, i.e. the Fans turn on to high speed when power is of or in sleep mode. I may have accidentally found a fix (all the reset procedures have not worked for me).

    System Preferences, Energy Saver:

    Computer sleep slide - NEVER
    Display sleep slide - NEVER
    tic HDD to sleep
    tic wake up for network...
    tic power nap...

    Then leave the computer on without any interaction until the screen goes into a "screen saver mode" (thats sounds a bit strange that because you have selected NEVER).

    And that fixed it for me! Been running like it should ever since.

    Strange.

    Do your fans now have no control? If so, that is a bad idea.

    Perhaps install SMC Fan Control.
