It’s very real. Ruined people’s lives and even negatively impacted plants and animals nearby. He also performed an experiment on people at a con with a control group and a group being hit with infrasound to prove out the effects.

Benn Jordan has an excellent video on this where he investigated infrasound and spoke to people impacted by it. Well worth watching.

There was a post about this on the Framework Community forum ages ago, and as of the last time I checked (which by now was like six months the ago) the only solution was to tape over a few of the exhaust holes on each side of the back of the GPU module.

It’s counterintuitive, but it actually helps airflow since most of the heat actually comes from the CPU, so the hot air is forced out the sides more which helps keep the CPU cooler. It also helps the whine when the fans are at full tilt.

Yes, they are. That’s why they released a gaming GPU as an option at launch.
