If you can't find red LED fans, you can always find clear plastic fans with blue LED's or white LED's, then just get some cheap red LED's and take out the blue ones and solder in the red ones, use a bit of glue to hold them in, and you've got red LED fans.
The Rosewill ones are hard to say, I bought 4 of them (blue) a while ago, one of them blows a ton of air, one of them barely blows any, and the other two are in between. If you run them for a while, they get faster (guess the bearings wear down and spin better, though louder).
