5400hz sound from dGPU fan on new Framework 16

Got the new GPU module today and it didn’t fix the issue. So it looks like there is something up with my laptop chassis that is causing the whistle. It definitely seems to be an air caused whistle sound rather than a noise caused by electronic coil whine. It sounds very different than the coil whine that my cheap higher power USB-C power supply makes.

To improve my ability to test the issue I got ectool working to control the fan duty cycle to isolate any noise from putting the computer under load and the noise caused by the fans. (see this post)
I was able to run my shell module at 100% fan duty cycle and I noticed the whistle. It was more difficult to get the shell module to that fan speed using a stress test and it doesn’t start becoming really noticeable until around 60% fan duty cycle which is why I didn’t notice it previously.

This is an audio clip of the noise:

Does anyone else hear a sound like that. It is ~5400-6200Hz.
