And if you are seriously into performance, you shouldn't care what the fans look like.
I didn't mean it that way.
I meant that theirs fans are very nice, but there are also other comparable companies out there that have similarly specced fans and look better in the case. If they were one-of-a-kind, i wouldn't care what they looked like
Because people can recognize Noctua fans instantly by the horrid colour scheme, combined with their reputation for being amazing means they get noticed easily.
If your willing to go to some pains, you can dye them to change colour (spray paint ruins the balance of them). I also think that Noctua re releasing some of their lineup in a purely black version. http://www.youtube.com/watch?v=E7Y9dV0XX6s
I just got my NH-U14S the other day. It was my first cooler/heatsink ever to buy and yes, when I looked at the pictures I thought like you. But benchmarks don't lie, so I went for it. I tell you... The moment I opened that box and that huge ugly fan was staring right through my soul, I was in love. There is really something special about a fan which appearence is so different from others. And I can't wait to see people's reaction when they go like "Duh, that's ugly as hell. It looks like something that was made pre world war. It probably generates more heat than it cools LOL!", and when they see that beast in action they are blown away. And I mean literally... like SWOOSH.
