I thought it was fishy how he somehow claimed that the two deltas were quieter than the phoenix's 3 EK fans. Maybe EK fans are just loud, idk, but it would have been nice if he had actually tested that.
FWIW Linus did a piece a while back about clickbait titles and how he regretted them but found them necessary in the current YouTube ecosystem. He compromise was to make two titles, the first one clickbait and the second one descriptive. So admittedly, "watercooling is dead" is just clickbait, and the real title is "tMeet the THERMOSIPHON!" which tbh also seems like clickbait but whatever. He is also launching a new company (Floatplane) with the goal of addressing some of these issues, however it does so with a subscription service I believe.
In other words, this kind of thing is the price we pay for free content. But does it have to be? Gamer's Nexus seems to do a much better job generating revenue from live streams and merch without all the clickbait and crap, but it also seems like a smaller operation. Linus seems to have a ton of content under different channels for a wide variety of audiences. Anyway, this has turned into a discussion of youtube and why Linus would claim some marginal prototype has killed water cooling vs the actual prototype. Either way it looks cool!
