I bought this fan before I realized it was only 950 RPM. I needed something at least 1800 to keep my CPU cool using an adapter I found to fit a 120mm fan onto a 70mm housing. That was my mistake. I did however use this fan to replace an aging noisy PSU fan I had, and it works great. Kingwin fans last longer than any I have ever tried, and don't get noisy like most. They are my first choice for all of my PC's.
This thing is super duper quiet, I have it powered by molex to just run at full speed and it’s nice and silent. Lots of value here for what I paid, I definitely recommend this for a nice stealth black fan.
