Piezoelectric fans. They have very limited use. They are very small and don’t have moving parts, so they last a long time and can fit in a compact space, but they move very little air compared to the power they use. In most cases, a traditional fan is better.

Since there’s no moving parts in these fans in theory they should last decades, but at 900 bucks a pop last I saw from Linus video and them having very limited applications, maybe home server for rich people lol.

Not to mention this kind of vibrations is top notch to catch tinnitus

A fanless fan, cool.

What’s making them oscillate like that?

Well don’t fucking touch it asshole

This is a Piezoelectric fan.
1. They suck. They’re extremely difficult to make (require very precise calibration), very expensive, but most importantly, extremely inefficient. They have rare use cases in very weirdly shaped… cases, but otherwise they’re literally always worse than a regular fan from a raw efficiency perspective.
2. They make a HORRIBLE sound for people with tinnitus (me) and I fucking hate them. This is definitely a case-by-case thing, but I’m writing off the whole species because of one bad experience like a classic bigot.

So this is what $7,700 bucks of cooling setup looks like…

They’re like the ornithopters in Dune.

piezoelectric motivators … Those used to be very expensive idk if they still are ,last time I seen them on a fiberoptic phone hubs server rack that belonged to a three letter agency.. it had went underwater during a hurricane and we were clearing it out , I got a 20 tb SSD out of it that used volatile memory(like RAM) instead of nand flash , probably why they’re okay with us cleaning it out because as soon as it lost power everything disappeared

STOP TOUCHING THE VERY EXPENSIVE COOLING UNIT!

Weird flex, but OK

Piezoelectric fans. I believe LTT made a video on them, they are extremely hard to produce, they are incomparable weaker than normal fans and they are expensive as hell. Only positive is their reliability (they are extremely reliable), WHICH IS WHY YOU SHOULDNT TOUCH THEM.

LTT had a video on these a few years back

I’ve seen that before for speciality requirements. I don’t recall whether that was power draw, noise, or longevity.

That’s cool.

LTT did a video on it a few years ago, they are good but stupid expensive.

The description says “piezoelectric fan”
That’s neat!
Linus tech tips has a vid on theese
kinda reminds me of bees cooling their hive
wow that looks trippy

Get a bunch of these and a high voltage(+-50V) sine amp. It’s not that difficult.
