I generally don't put a lot of stock in the ranting and raving of the <br>
gamer kids, but I've used these Noctua fans in a few different <br>
applications, and I'm absolutely amazed by them. Serious fluid dynamics <br>
engineering has gone into these things. They are worth every penny, no <br>
joke, and no gamer-kid-in-mom's-basement BS.<br>
<br>
Note that I stopped short of saying they "blew me away". ;)<br>
