Scythe makes amazing coolers for HTPC's. When you are watching a movie, you want no sound, and Scythe coolers are VERY quite, Just don't plan on doing any OC'ing if you want the noise down.
i love how these look but these prove to be lousy at cooling. there was some big HSF shootout on here a few years back and it pretty well proved that just about ANY tower cooler and a few OEM-style sinks are able to out-perform these V-style coolers.
