So to me, it sounds like it will cancel sound with sound. If that's the case, is the new noise any better? I'm guessing high-pitched noise out of hearing range, but even I can hear those sometimes...

my buddy's mother brought home $17612 past month. she has been making cash on the internet and moved in a $580200 house. All she did was get blessed and profit by the steps shown on this site yuarel.com/readme

The solution to fan noise is simple. Stop using bladed fans and use a squirrel cage blower. They are much quieter and move more air anyway. That's why they are used in HVAC all over the world, and why Dyson invented their new "bladeless" fans (there is a squirrel cage blower in the round base of each fan model. The rest is just ductwork.) I presume the ubiquitous bladed muffin fan design was born of cost cutting measures But if you are going to start adding technology and raising the cost, it might be cheaper to just switch styles. However, many models of muffin fan these days are quieter simply because they use a larger blade and run much more slowly. So I wouldn't agree that it 'can't' be done when wanting to quietly cool a hot high-performance PC. It comes down to buying the right fans and having a case large enough to use them.

This is simply disruptive interference. I am surprised that nobody has attempted this before. Well it would make for an interesting science fair project.

I can say it is a little surprising no company has put something like this into production before. Since this is such a simple concept that most people learn in high school science, maybe there's a complication in the process that these companies didn't deem worth the expense to invest in until now?

I would love to see how these stack up too. I don't OC so haven't felt the urge to move to water cooling, so I use several fans still. This probably could replace 2-4 fans, leaving 2 originals. I DO wonder at the price though. I don't plan on paying $20 per fan.
Honestly though, i don't really have a problem with my current fans except I want more CFM... my old HDDs make the most noise when they wind up, but they're currently extra drives and only run occasionally at least.

I love this idea. Unfortunately I have the sneaking suspicion that those of us in the "no budget to spare" category will have a hard time compensating for the additional price bump.

Love to see this on video cards too. Hate it when I'm playing some graphic-intensive game and all of a sudden it sounds like there's a typhoon going on inside my computer case.

I can't wait to see how these stack up against the Gentle Typhoons. I might try and hold out for these.
