I also have the one without the stand.  These are expensive fans, but the quiet and the quality justify the price in my opinion.  I have this one aimed at my rowing machine, and it works splendidly during workouts (on 99 :-).  The "tabletop" one is in our bedroom (on 1), and gives a nice gently no-noise breeze.

The remote control works well.

Wow, what a great fan. I've had it for a couple weeks, and ran it constantly since I put it together (which took 5 minutes).  Really really quiet on lower settings, and only wind sound on higher settings.  It's all I could expect out of fan. When you put it together, you'll know exactly how to take apart to clean it, which is simple and easy.  It was expensive, but on the other hand it's everything I want in a fan and it won't stop working or get rattly. It looks nice too. It's the Lexis of fans.

This is a good fan, way quieter than the cheaper fans I usually buy from Walmart.  Been using this fan for about 3 months and it meets all of my expectations.  This fan moves a fair amount of air, even on the lowest speed.  Speeds 1 and 2 are quiet and the noise increases as you go to speeds 3 and 4.  The highest speed 4 (Turbo) is fairly noisy.  Fan assembly was easy and the overall quality and construction seems very good.  If fan noise is a problem for you, then this one is definitely worth the extra money.

The GELID Silent 80mm fans are very quiet and are a great replacement for the noisy plain bearing fans in my hard disk enclosures. The price is pretty high on Amazon.

Really great fans. Love the lighting and the Airflow is simply incredible. If you are looking for fans that provide really great air flow and not too much Noise then these are worth checking out. For the price is not bad either. I have purchased more expensive fans and have been less satisfied with them. These on the other hand I am more than happy with. I definitely will be purchasing more of these in the future.

They also have a nice LED light that is noticeable. Overall you cannot want anything more at this price. The cord was long enough to put them in the front, top or back and reach the Fan controller or motherboard easily. See the video and you can not hear anything on these fans. Corsair is really high quality, I am more than impressed by these at this price compared to other companies that charge more for the same or less quality fans.

I was at first hesitant to purchase this fan because of the high price.  BUT I was a little enticed because of the no interest option I got.  Since owning this fan for approximately 4 weeks, I can say without a doubt that I love this fan!  Others have complained that it is loud on the highest speed, but I find it no louder than my other tower fans.  On the lower speeds, it is almost whisper quiet, its rotation in very, very smooth and the air coming out of the fan seems "smoother".  Putting the three pieces (I think it was only 3) together was very easy as they have arrows lining up where it is put together.  This fan actually takes up less floor space than my other towers fans, which is a plus to me.  If I had to do over again, I would not hesitate to re-purchase this same item.  Take the chance, you won't be sorry.

These fans are really well built and packaged, and have a fantastic set of accessories included to adapt to any situation you may have.
They are extremely quiet and they actually engineered them to be so with the design of the blades and other features.
I have one in my main computer exhaust and bought a smaller (40mm) fan for cooling the solid state drive - both great.
I won't use anything else in the future...

I'm 'sold' as a Noctua fan fan ;-)

Noctua is one of the best fan makers out there, and this product is no exception. It comes with a plethora of accessories, which includes rubber mounting pins, regular screws, an extension cable, low-noise adapter, and a Y-splitter. Even the box it comes in is high quality. I'm using this fan as an top exhaust in a Corsair 650D, which came with pretty mediocre fans. I definitely notice a drop in decibels with this fan. Even though it is a tad more expensive than other fans, it is definitely worth it. My only complaint, like many others, is the odd color scheme.

Pros: Quiet, high quality, includes many accessories
Cons: Color scheme

I upgraded my small-form-factor Silverstone Sugo-based PC to have more fans and replaced the stock hard drive cooling fan with these Arctic fans. I can't believe how good of a value these fans are. They are some the best (quietest, good airflow) I have tried but they are as inexpensive as low-quality fans. The PWM daisy chaining is ingenious. My PC is now about as quiet at full-speed, even for extended durations, as my PC used to be at idle. Check out their CPU coolers too. An excellent upgrade over stock.

I was extremely apprehensive about paying literally double the price than most other LED fans, whether they claim to be silent or not or simply perform miraculous feats of cooling cases to -20 under room temp. but, I am building a small and clean Hackintosh for wife's upcoming b-day and felt it worth a few extra bucks to  have a truly quiet machine. something about silent PC's just make them seem  of higher quality, and of course, they don't become annoying to sit next to for hours on end. I didn't know much about Cougar as a brand, except my son got a gaming mouse of theirs over Christmas and it's of stellar quality, so that made me feel comfortable buying a pricey fan. anyway, glad I did, it moves a ton of air and it's stupid quiet. the LED's are of standard placement, on the inside of the corners like thermaltake or coolermaster, nice bright look without being obnoxious. I like the added shape to the frame, the white rubber feet that are pre-applied to both sides have a recision fit/finish(unlike a few other lesser companies that give you a set of sticker pads that are a PITA)  and I've never seen or used the tool-less rubber pins, but I can only assume that this only helps to decrees noise by absorbing some shock between frame and CPU case. five-stars, I'll be keeping an eye out for some deals in the future, I am pretty much going to be forced to upgrade my other two builds with full sets of these now that I've experienced a quality case fan, it makes a difference. I am eager to try even more Cougar products, they've impressed me twice now and others seem to feel the same way.

They are quiet loud, but I guess that is somewhat good in the fact that its blowing air.  The fan blades are kind of small so if your aren't within a foot of it you don't feel the air coming from it.  It works great, but there is no on and off switch or different speeds.  The fan also kind of heats up where the motor is, so don't touch that part if you adjust it while it is going.

My computer's fan is noticeably quieter while temps have dropped considerably. A kittle expensive but it works so I can't complain.

Nice, well built fan, that isn't too noisy, even at highest fan speed.
Yes, it is worth the extra money.  You do get what you pay for.

Nice quality fans that are heavier than the average fan. The fans are very quiet and push lots of air. They also look great in my Corsair 250D case. The fan's color rings add a nice touch to the fan design and computer case.  Do yourself a favor and not to go cheap on case fans if you want long lasting fans and a quiet room.

These fans run well and quietly. I'm not a fan of the brown corners, wish they were black or came in options. I'm not going to pay extra just for replacements in whatever color.
