Query: EXCELLENT!!!

After reviewing all my options to fix my noisy CPU....I decided to do a little research on what is the best out there......and it led me to find this nice and beautiful fan that is absolutely quiet. I have never had the experience to remove nor install CPU fans and with a lot of research from YOU TUBE and following the manual for installation I was able to nail it and now I am a happy camper with a very quiet CPU. This is really cool. My original CPU fan that came with my Phenom X6 would blow up to 7,000 RPM when the temp reaches 48 degrees.....it was simply NOISY and I couldn't take it any more. This Zalman fan is humming at 1900 RPM like a happy camper.......and I am very happy and satisfied indeed. This is a 10 star CPU fan!!!!
