Pros: Cheap for a pack of 2, move air well, speed about as advertised (more on this in the cons), quiet, solid choice for cheap case fans if you need quiet air movement.

Cons: Both fans show up in hwinfo64 as running at ~1050RPM, which is within the margins that Rosewill specifies, but still a little disappointing that they don't run closer to 1200RPM for the extra bit of airflow. Both fans vibrate noticeably when horizontal (impeller facing downwards, pushing air up). I've had several FDB fans in different sizes and they never vibrated as much as these do when mounted horizontally. Doesn't give me a lot of confidence in the fans' longevity if mounted in that position. They're smooth as butter when running vertically, though.

Pros: Fans are quiet and seem to move air fine.

Cons: None.

Other Thoughts: Two fans included with mounting screws. Easily mounted in Rosewill R5 Black case. You will want to install the fans before installing your motherboard.

Pros: Very quiet and has great CFMs. 140mm fans are always a plus if your case supports them, and these Rosewill ones are dirt cheap in a 2-pack.

Cons: No LEDs. 3-pin connectors. Plastic itself looks a little rough, like these came fresh from the molds without any finishing work done.

Other Thoughts: If value is more important to you than looks, or you just don't want your case to look like a riced-out Civic, these are absolutely the way to go.

Pros: Price. Quality.

Cons: None

Pros: -Comes with 2 for $15
-Very quiet
-Moves a lot of air

Cons: None really. Obviously these are just plain black fans so no fancy leds or anything. The cables aren't sleeved but they are black/dark grey wires so they still look good in a case so not a con

Other Thoughts: I have the GX700 case from Antec which came with 2 140mm fans and 1 120mm. I'm utilizing the fans that they came with and they move decent airflow and are quiet but once of my 140's stopped working and the other one developed a clicking sound if your 7w+ so I needed replacements. These fit the bill cause their plain black and came with 2 fans. They actually have more blades than the antec ones and push waaaaay more air and are quieter than the stock antec ones. These fans are fantastic! So if your like me where your stock fans stop working or simply want to add more fans to a case without leds (assuming you don't have a window or just dont want leds) than these are your fans! they are a steal!

Pros: Just got these yesterday & put them in my Cooler Master HAF. Very quiet & well built fans. They do move a lot of air.

Cons: can't keep my gin & tonic cold
