-Speed Control Knob
-Quiet at low speed and moves large volume of air at high speed
-Essentially silent at up to 33% power
-quite loud at higher speeds
-uses up to 6w at high speed
Just temper your expectations of being able to run it at over 50% power unless your computer is in another room or you're wearing headphones.
However if moving air is the first priority (sound level be damned!) then this is what you're looking for.

using this fan as a pull fan for an corsair h70 and stoke fan for puch wors ok but -1c to nosy not worth it as a case fan for cheep case ok to loud

Experience: 4 Years

Experience: 2 Days

Awesome wind maker, tolerable sound.
I love this fan but I got a Silver knob instead of a black.. but Nicx said for me to rma it and they will send me a black one.

This is an excelent fan and I plan on using it at only half speed most of the time.. its very quite except when your maxing it.

Experience: 38 Days
110 CFM, duh.
It is loud
OK, its powerful, and its loud, but i sure hope no one expects quiet at 110 CFM, i use 2 of these to cool my CPU and RAM and yeah, there is a lot of air moving inside my case, as cool as it can be.

Experience: 6 Months
Adjustable fan speed, high CFM (110) and nice white
Closed flange :(
This fan is currently used with my Thermalright SI-128 heatsink and thanks to the controller, I can adjust the speed to find the sweet spot between cooling and quietness, something other fans cannot give.

Experience: 1 Weeks

Pushes massive air
Not as loud as expected
Silverstone quality
cool floppy bay fan controller
knob on fan controller too big for sonata
I bought this fan to cool my P4 Prescott (3 ghz) processor with my Zalman copper flower heatsink. It does a great job dropping the temps on my CPU by 10c over a 120mm Vantec Stealth fan. It did all this without adding too much extra noise. My CPU is now at about 45c, not bad at all when the stock intel cooler is about 74c.

Moves alot of air
Speed Controller
Loud but is pumpin out 110CFM so i can deal with it
Great if you want real cooling. Lowered my system temps my 10 degrees. The fan controller is very handy with the comp is just sitting idle.

Experience: 1 Days
None that I can see.
Fantastic fan! This thing moves a ton of air. I just put one on my new Noctua NH-U12 cpu cooler and it's doing a phenominal job. It dropped my idle temperatures on my E6600 by 12 degrees and my load temperatues by closer to 20.

This fan is a tad loud if you run it on full, but full is probably more air movement than anyone needs. I'm running it at half speed with great results.

Very happy with this fan. Can really tell a difference between this and the cheap, 5 dollar ones you can buy.
