XIGMATEK FCB (Fluid Circulative Bearing) Cooling System Crystal Series CLF-F1251 120mm Blue LED Case Fan, 2 pcs in 1 package CFS-SXGJS-BU2

Pros: They move a lot of air and are very quiet

Cons: I got the wrong version of fans, the led's on my fans are purple NOT blue and it does not match my case at all!

Other Thoughts: If I got the right fans they would get 5 eggs.

Pros: They are quiet and have bright blue led's. Enough airflow.

Cons: Wish the airflow was a little better but it's plenty for what I have them for so no big deal.

Pros: Clear housing looks good if mounted on side panel with a clear Plexiglas window.
Cable length is good. Appreciate that wires are silver instead of the ugly multi-colored wires.
Air movement was good in an exhaust application only--not as intake in my system.

Cons: Brightest blue LED I've ever seen--it definitely lights up the interior of the case.
Very loud as an intake on an Azza Spartan side panel with round holes, but quiet as an exhaust. Little quieter on a Rosewill Blackhawk with honeycomb shaped holes on side panels.
Disappointed because wanted to use them on side panels in a system I'm building for sale.

Other Thoughts: If I'm eventually able to use these, it'll be in the case interior only, not on side panels--LED brightness is too distracting for my taste. One fan goes a long way, two or more would be entirely too much.
Wish case vendors would offer solid holes on side panels with grill guards instead of dozens of small round or honeycomb shaped holes. Think those designs negatively impact dynamics of air movement resulting in whistling and humming fans.

Pros: They look nice, and actually work. I myself love them. I have them both in my new rig and internal temp. is always down.

Cons: The wires could be longer for better wire routing.

Other Thoughts: Nice color.

Pros: The CFM on these fans is impressive for the price. They are set at around 1500 RPM which makes them nearly silent. The LEDs are extremely bright, brighter than I expected.

Cons: That I can't fit more into my case.

Pros: Amazing fans. Easy to install and get set up.

Cons: None

Other Thoughts: My case was set up for 2 extra fans on the top but could only fit one, but thats a case error. The blue added a new feel to the all green case.

Pros: Very Cheap, Blue LED's match the ones existing in my system. They are also relativity quiet. Pretty Happy with them.

Cons: Intake air flow is not that great. Fan speed is not especially fast. Fins seem to jiggle ever-so slightly; might be due to semi imperfect fan construction.

Other Thoughts: Fairly easy to alter the outer casing. I added one as an intake on the bottom left side of my case so I needed to cut little ridges the left casing to fit it in with my psu.

Pros: When I plugged the fans on the motherboard, they were at max speed and loud. Now that I've plugged them on my case fan controller, they're very quiet and move good air through even when on lowest controller speed

Cons: None so far

Pros: Extremely quiet! Ever since I went to a liquid cooled CPU, I didn't need the wind tunnel in my Antec Nine Hundred anymore. So, I finally bought some new fans, and these seemed promising.

They are a rich, darker blue, not the blinding white-light bright LED blue you see on a lot of the other fans.

They push plenty of air over my hard drives and suck the heat off of my CPU's radiator just fine. My CPU or hard drive temps did not increase by going to these fans, but my office is WAY QUIETER now!

Cons: None that I can see for now. I'm excited to see if this Fluid Circulative Bearing requires me to lube it with 3n1 oil every 6 months like all of my other fans have. Hopefully, they don't require me to touch them.

Pros: -Quiet if they work right.
-Led lights are bright and make the case look good
-Cheap

Cons: I bought two packages so four fans in total, on 2 fans i can use properly. The other two fans if they are set at any speed above 20% they make a very loud and annoying humming sound.

Other Thoughts: Its a risk, you get what you pay for
