better to choose imac18,3 as system definition or imacpro1,1?

iMac18, core i processor

The table in #1 shows "TBA" for Coffeelake

As of this date, no native Coffee Lake desktops exist; no native CPU PM support

Is this the same problem here? Powermanagement? Whispering is annoying

GPU PM is available.

Hi!
I have i8700, gtx1070ti on 10.13.6, iMac14.2
The problem is that in the idle mode - the fans of GTX are spinning on (for a second) and off constantly.
Can this problem be solved by AGPM, e.g. by changing the g-states?

PS: Tried to change the kext, nothing happens..
AppleGraphicsPowerManagement.kext is lot loaded in extensions report (about Mac).
PPS: Maybe it's just the broken graphic card.
Thanks.

AGPM does not control fan speed, it manages power.

I got it running!
And I know that AGPM can't manage speed fan. But theoretically if we disable state 3 (idle) of the card, the problem with the fan should go away?
I will post more files and screenshots soon.
Thanks.

State 3 is not idle

State 3 is not idle

Can you help me please with that? How can I disable idle state and thus solve fan stop issue? Thanks.

Your graphics supports 16 power states; why did you decide state 3 is idle?

Contact the graphics card manufacturer
