Both of those examples wouldn't have gotten traction in the pre-AI HN in my opinion.
The Lenovo laptop jet is experimental and the details suggests that it uses 7.5w to cool 30w. That's not very efficient. You might as well have a small fan and let it spin at a low RPM to reduce noise. There doesn't seem to be a breakthrough here.
The Brax industries one is just an ad from the company's official Youtube channel. I don't think the product is interesting at all.
Looking into it more, it seems like the actual consumption is close to 1W per module, for an approximately 1:7.5 ratio. Regular fans are still likely more efficient, but the other advantages of the "AirJet" make it interesting.
I thought so, too! There aren't too many in this field that do this and I think they deserve some recognition only because of that. They're also not entirely new, their previous product has been around for a while.
