Pros: VERY QUIET! My system must run way cooler than some of the other ones here, My CPU doesn't go above 40 (even when gaming) in most cases. so my Fans are usually low throttle. VERY good fan for the price!! Cord was even braided in black- NICE

Cons: NONE

Overall Review: Great buy for the price. Good PSU replacement as well.

Pros: - PWM Automatic speed control. - Quiet - Price - No neon lights (I consider it a plus) - Fast Shipping - 4 pin power connector

Cons: -None

Overall Review: - I was looking for an extra front fan for my case to cool HD cage. This works pretty good.

Pros: Bought this to replace a Coolermaster R4 in the front of my case blowing over the hard drives (with the intention of moving the R4 to a side mount to blow on the video cards). This fan is PWM controlled versus the R4 which is not.

Cons: While this fan does move more air at full speed than the R4, it's also a LOT louder when doing so and tends to vibrate as well. I have rubber grommets on the case where I mounted this, so I didn't need/use the include rubber fasteners. At half speed or so, it's much quieter and the vibration goes away, but of course so does the amount of air it moves, to the point where it's less than the R4 at roughly the same noise level. Also, mine has a slight clicking noise at mid to slow speeds (level 4~7 on my Asrock Z68 Gen 3 motherboard). I'll be reinstalling my R4 back in it's place and picking up another R4 for the side mount blowing over the video cards.

Overall Review: From the specs and design, this appears to be an Akasa Apache Black fan, but made by Rosewill for around half the price. While the specs say max 22 Db, I'd have to say it's considerably more than that. However, the front of my case is ~2 feet away from me on my desk.

Pros: Pushes a ton of air. 4-pin cable is sleeved AND long, so it'll fit most spots on a mobo.

Cons: Loud as others say, BUT... that can be controlled by either your mobo (if you can) or a simple program called speedfan.

Overall Review: It's a case fan, not a server rack fan, you don't need at complete high speed to still move air and cool the system down.

Pros: Over 100 CFM!!! The think to remember folks, is that you don't want to run the fan at 100% Right? So you take the CFM at 50% and that is still as much air as all the other "Quiet" fans out there. Theses fans are very quiet at 50% to about 80% They move a lot of air close to the blades all the way to 4 feet!

Cons: There is a reason these fans are constantly out of stock..THEY are too GOOD for the price..the secret must be out...

Overall Review: Just because you got a bad fan there is no reason to hate!, I just had a bad "fractal" fan and I sent it back. BTW I am not too impressed with most of the fans out there. In fact I think many of the cases are getting a bad rap, because the fans are not as good as they should be.

Pros: -Very Quiet motor. The noise of the moving air through the filers is audible at 100%. -Silent at 50% and Below

Cons: -Blades can really give ya a good finger smack if you mess with them while operating! =[

Overall Review: I currently run 4 of these and If I didn't use filters on all my fans then I would not hear a thing from the fans when they are > 50%

Pros: These fans are sick, i have three of them installed on my 420 rad 11 fans total in my case all of them 140mm. these fans run at 100% all the time and they are as quiet as my other fans running at lower rpms, they push tons of air because the high static pressure.

Cons: none

Pros: -Move a lot of air -very quiet when functioning properly at low speeds and relatively quiet even at max speeds -pwm is a nice touch

Cons: -only came with rubber isolators, no screws. The case I purchased had too small of holes for the isolators and these fans are about 0.5mm thicker than a typical fan is for some reason. This means the screws are a little too short and the entire fan casing becomes warped just to mount it. For the price I got these at ($13) I thought they would be a steal, but that is pretty annoying. -However, the bigger issue is the pulsing sound accompanied by these fans. I am not sure if it is poor balancing or bearing, but they make a very noticeable pulsing sound at all speeds, but you only really hear it at low speeds when it isn't covered by regular fan sounds. If you live in a noisy house or always have music or sounds on, you might not even notice it. But my computer is only around 3 feet from my head and I often work in near silence, making the fan very annoying. I bought 2 of these, one of them always pulsed and the other originally didn't. I sent one in for a replacement but then the 2nd one started so I am not very confident. I tried placing these fans in multiple orientations, multiple speeds, and without the case warping them, but to no avail. I will probably eventually get fed up with these and get different ones.

Overall Review: -Would not recommend unless you live in a noisy environment, use headphones constantly, or don't mind a pulsing fan sound.
