I just ordered one of these laptop coolers with dual LED 50mm fans (link):
It was only $8.50, I figured I'd take a chance that I could just remove the fans and use them. Should be here in a couple days, so I'll update this thread when it arrives and I figure out if they'll work.
I appreciate the links, but those are just normal non-LED fans. I've actually got several of them, but would prefer something a little flashier. I'm installing a window in my case, so a little bling goes a long way.
