Summary: This is a very quiet cpu cooler that will be fine in most home applications, including Home Theater / HTPC machines. It isn't silent, though, at least not on my core i7. It puts out just enough noise for a microphone to pick it up while recording vocals. It's also big - just fits inside my Silverstone case. Very easy to install, and it keeps my cpu temp at around 45 c, even doing demanding work. I just wish it were a little bit quieter.
