Yesterday I fitted a Sharkoon Silent Eagle 1000 in the side of my Coolermaster 830 Stacker. I bought it after the recent hot spell thinking that it would help cool my 7800 GT OC which hit 71c at one point. I have the Sharkoon blowing down directly on the the Gfx card. The fan is to all intents silent but it has made no difference whatsover to my temperatures. The reviews on the Silent Eagle 1000 are, to say the least, mixed. If I were you I wouldn't bother with this fan.
