Good quality, great airflow.

Great airflow and relatively quiet given that is a double fan. I will probably purchase another for my study/craft room.

Bright, good airflow, quiet. They do their job perfectly. I bought fourteen of these fans all at once and every single one works perfectly.

seems to move a good amount of air for the noise level. i have it right up next to the backplate on my gpu (thats where it fits on my case/mobo and not be competing with the gpu for air) and was worried while installing it it would not blow anything out but it seems to be working great.

Works great, Solid build, moves alot fo air. A little noise but it was expected to be. 10/10 fan now i just hope it holds up!

I have had this fan clutch installed for a month now, and my 7.3 IDI engine is running cool, an A/C is cooling
much better. I really like the quality of this fan clutch. If I have any other vehicles with a failing fan clutch,
I'll be purchasing another.

Pros:
Significantly quieter than AMD stock cooler.
Keeps the system about 20 degrees c lower than the stock cooler under load.
Quite easy to install.
Nice, solid quality all around.
Includes everything you need.
I can run my A10-7850k at the full overclocked 4.3ghz speed without the computer threatening to take off like a helicopter...

Cons:
These are very specific, so they may not apply to you.
This thing is huge, much larger than any heat sink I've used before. That causes some issues
On the Coolermaster Cosmos S case, it conflicts with the 200mm case fan. I had to remove this fan to make the case fit back on after installing this cooler. It may be a problem on any other case that is the normal height from the motherboard to the opposite end of the case that also has large fans.
On the Asrock A88X Extreme 6+ motherboard, it blocks one of the memory card slots if the fan is installed on that side. This is fine if you're only using 2 dimms however, just switch to the second pair of slots. If I ever upgrade to 32gigs, I'll have to reverse the fan and have it blowing hot air across the memory chips, and revise my case cooling system to match the new airflow direction.

I am very satisfied with the quality of these Silverstone Tek 120mm Fine Fan Filters, since the installation of the fan filters (which was stupidly easy) the amount of dust in my system has dramatically decreased. I have to clean the inside of my desktop significantly less.

The only downside I can see is the fan filters are restrictive on airflow, which is expected.

Very happy with the build quality.  This feels like a solid fan.  I am also pleasantly surprised at the fan's effectiveness, given that it's running on USB power.

Also, it's got great airflow, 1 USB 3.0 front I/O, and it comes with one case fan. Score.

Works great. Styling is quite interesting, and probably a bit over the top. Works as advertised. One of the quietest and highest air flow case fans available. Great balance of price/performance/noise/reliability.

Haven't tested it in my build  but just out the box I was surprised at the quality and appearance it seems equal or even better than the noctua fans. If there is issues I'll edit this review but so far I'm impressed.

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.

Fans are almost entirely silent and move a decent amount of air. This fit in a Corsair Obsidian 250D with room to spare, so I'm very happy about that. Temps stay in very acceptable ranges. However, I did need to reverse the fan direction for my case as the fans were orientated to blow air down and pull through the heat-sink. I made the fans push the air through the heat-sink and up so air could be removed by my dual 80mm case fans above. Incredible quality and packaging (If Apple made heat sinks and case fans, this would be it) and I couldn't be happier.

I bought this to transplant a server from a tower to a rackable option.  This thing is enormous inside, great for airflow and those who would want enough room to water cool something like this.  The 3 mid mounted hot swap fans, which are actually standard 120mm fans in a custom mount, are very quiet.  The whole front is made of heavy gauge aluminum and feels solid, though time will tell.  I presently have all my drives, save one, in hot swap racks.  The card keepers seem a bit on the light duty side, but I guess they do not need to be rock solid.

I am impressed by the foresight by the engineers of the case.  The mounting ears have horizontally ovaled holes on them, so if one needs to take the handles off of it, and make the ears mount closer together, one can still mount it in a standard rack.  This was my case since I needed to be able to close a locking door.

I like the fact it can basically hold any standardized motherboard in existence sans BTX and the similar, BUT, and this is why I gave it 4 stars, the motherboard tray is not removable in the common sense of the phrase.  Yes, it can be removed, but one cannot remount it with a motherboard actually installed on it properly.  It is held in by 4 screws and 4 tabs that slide into slots.  Once the board is installed, one cannot mount the screws to secure it.  I guess if you really want to, you can rely on the PCI cards to secure it from sliding out of the locked position, because with the tabs on the tray, it will not fall out, only slide to its removable position.  Also, the motherboard tray does not have a cutout on the back to mount a rear retention bracket for CPU coolers if they should need them.

The PSU mount point is very deep, and able to accommodate many types of PSUs.

Overall, I am satisfied, and I will buy this again for my other servers.

Great air flow and good sound. I personally want some sound out of a fan as it is a blocker of other noises. This is a great fan!
