    My temp at idle is around 42C,gpu fan off.I surfing the internet,temp go up to 49-50C and fan start to run.Fan is running and running and wont turn off.I open kombustor and my fan automatically shut down.Than I open hwmonitor to cheeck my temp and it is 32C.Fan should turn off by itself at that low temp.

    Also I think that when surfing the net without kombustor my temp never go up to that 50C and no need fan to turn on.

    Also If I want to check temp on hwmonitor I can open furmark.Work same as kombustor.

    It's known problem that dwells in nvidia optimus aswell, no drivers have ever fixed this yet, but the solution for this is to open an application that stresses GPU (like furmark, 3dmark, gpu-z etc...) that'll make fans go quiet if the temp is low enough.

    On nvidia cards you could also open driver management, but with amd this doesnt seem to work

    I have this as well, but it's extremely minor overall.

    Yup, multiple issue threads related to cooling and fan profiles that the OP has even commented in.. Soon a petition will be started and hopefully that will lead to some results

    That's an interesting point. Maybe kombustor triggers a change to some power profie parameters or causes some kind of EC reset?

    Under normal operation the fan will start to spin when a given temperature threshold is crossed. It will then stop spinning when it strikes some temperature threshold that is lower than the higher threshold. So if the EC is reset, then the fan will stop and won't spin until the higher threshold is crossed again.

    If you double-tap Fn+1, does it stop the fan for while?

    I can stop the fan by turning the turbo fan on and off (Fn+1). It does start up again soon. The problem ultimately results from the fan profiles.

    In "some" (even rare) cases (which are completly random as far I can tell) double-tapping Fn+1 will sometimes reset the EC and stop the fans, and keep the fans off as long as the temperature is maintained below the first fan kick-in threshold (e.g. via external cooling).

    The system can't be cooled completely passively, but it can keep the fans at bay for a while until the EC loses it's brains. But sometime, the fans can't seem to be killed by double-tapping Fn+1 even if the temperatures are below ridiculously low fan "stop" threshold... "Clevo logic" ≠ logic.

    doesnt work on my 150em :confused:

    Yes my fans are messed up. My gpu fan will still be going full blast after I close a game, I run gpu-z and it stops.
