Default Active noise cancelling CPU cooler

Very interesting idea! Here's a piece with video-

I'm a little disappointed that it does not seem to cut wind noise so much. This author makes a good point that video coolers make a lot of the noise in modern high-powered systems. Note that this does not use actual speakers. I could imagine something mounted in the case to take on noise in general. Maybe include a bit of adjustment to tune it to individual conditions. A mic and a couple of small speakers might be really interesting to play with.

Looking at the video suggests that some writers were just winging it on the details.

I think the writer at Tom's must not have looked close enough, or was just quoting. He thinks there are speakers.

But TechPowerUp also says speakers-

However, Xbit cites the blade vibration-cancelling ring-
