Summary: These fans are 'really' silent and reliable. I have installed them in multiple computers and use them for the computer case and the CPU heatsink cooler. It is easy to see why "www.silentpcreview.com" uses them as the baseline reference for comparison with all computer fans.
Summary: i can only hear the fan if my head is less than 1 foot away from the fan. it doesnt move tons of air, but it moves enough for what i need. if i needed more silent fans, i'd gladly get these again. edit: wasn't sure how to use the anti vibration mounts, here's what i did. i think you are supposed to use them instead of screws. so i use screws in opposite corners. in the other corners i shoved the rubber point thing through.
Summary: This fan pushes a lot of air and is nearly silent. I can hear my GPU fan over my case fans (these units). A very nice quality fan to replace your fans. Comes with rubber mounts as well for vibration. Very happy. Have had them over a year.
Summary: I have these fans in the front of my case, where they are very visible. The white blades look very distinctive without being overly flashy. But more importantly, these fans are QUIET. I usually get a fan controller/run on 5v/etc but I plugged these in and felt that I didn't have to. Plus, the noise they make is pleasing, no buzzing or whining to be found here.

Summary: They are quite fans, look good, and keep the computer cool. Mission accomplished! Note" i have a high quality antec case that came with "quite fans" with two speed settings. those fans on low are way louder than these...
