I have the blingy LED Yates from Jab-tech. They are a bit louder than the orange ones and pump a bit more air. They have a different blade geometry as well but well I didn't bother to think about what difference it would make. The Jab-tech ones are sorta low quality actually, the leds are so ghetto, hot glued on!!! and like one of mine came with a funny bearing and a broken led and the hot glue coming off, but overall I was really satisfied with the yate loons. Much more powerful than the retarded orange thermaltake thing in the front of my case. I kept the LED thermaltake, it was really quiet for some reason. Yate loons are very very good fans. If you buy like more than 4 LED ones you can get 'em 5 dollars a pop.
