GPU external fan RPM readout (Asus ROG Strix RTX 3090)

[VeilSide]

I wonder if there is a way to get fan speed reading which is connected to external GPU 4pin PWM header.

I have ROG STRIX RTX 3090 which has this feature of connecting 2 case fans directly to GPU instead of MB headers.

Sadly, the only way of making them fans functional is you have to run ASUS proprietary app which is a mess on it's own.

Thank you for the dumps!  Was the external fan spinning when you've made those dumps?  If it was stopped, can you please repeat those dumps when the fan is spinning?

Thank you!  Is Asus' tool capable of measuring fan speed in RPM as well, or only duty cycle percentage?

Only duty cycle percentage is available on their app. Does that mean RPM reading cannot be retrieved?

I'm afraid that's the case, yes

That's sad. Was hoping to add this external fan speed into my sensor panel 
Just wondering how are them fans only visible in their app. If I connect the fans without installing GPU Tweak III, they simply won't work. So basically need their buggy app just to run external fans which is ridiculous
