Custom Zero RPM profile is not effective on Windows lockscreen

[baybora]

Hello,

I created a zero RPM profile for my H150I Elite Capellix cooler and it's working fine. I don't mind the fans switching from zero RPM to low RPM from time to time but I have an annoying problem.

Windows screen saver is set to black empty screen and the timeout is set to 1 minute. Whenever the screen saver is automatically activated, the fans are starting to spin faster and louder. I unlock my screen, and after a few seconds, they are going slower and quiter.

I made another test by pressing Windows + L buttons and noticed the same situation. I think iCUE does not respect my custom profile settings and runs a balanced profile or something else. The screenshot below is taken right after I unlocked the Windows screen (with my PIN):

Is this a bug? How can I keep my fans silent on Windows lock screen (or when the monitors off) ?

Thanks

I would really like to keep my fans quiet 🙂 Any ideas?

You're not showing us the custom curve and it's control variable, so that leaves us to guess.  Mine is you used CPU temperature as the control variable.  When you lock your PC you sever the connection between the controller and the data and the fans max out.  

 

Another possibility is your coolant temp in that shot is 42C.  That's pretty warm for doing nothing but sitting around.  It's possible when you lock the screen and go to hardware mode, the controller is reverting to its base profile that will cause a large fan response at temperatures above 40C.

 

In either case, you may be able to work around this by using H150i Temp (coolant) as the control variable. That should save to the device and work without needing to fetch data through the motherboard.  Not sure why it is being triggered by the screen saver unless you have set the curve to GPU temp.  Possible GPU drivers don't know what to do with those old screen savers anymore.

Yes, I suspect so. I couldn't find any settings to control curve and it's variables.

Fixed RPM 600 is quiet enough for me. Thanks 🙂
