The new Xigmatek CLF Crystal Series of 140mm system fans continues the company's innovative design focus to provide advanced features and performance while maintaining excellent value to the end user. CLF Series is created with attention and detail, and not only does it look prestige from every angle it is manufactured with impeccable performance.

The CLF Series fan comes standard with quad LEDs incorporated with transparent frame and blades insuring your case fan to be the center of attraction.

The CLF features a high quality "Fluid Circulative Bearing" which is tested to increase its lifespan by 50%. The Fluid Circulative Bearing uses a remarkable re-circulative fluid method which enables the bearing to rotate at a high and stable revs, reaching rotations up to 1500 RPM. Unlike average bearings on the market, FCB will cancel out 98.9% friction which means in practical everyday usage this ultimately produces a near silent atmosphere (<20 dBA).

1 out of 5 eggsLOUD

Pros: The blue colored led is nice. It blows air

Cons: I got this fan because it says that it is quiet with >16dba. I was super excited by this. Now that it is installed there is a constant whining buzz similar to when a refrigerator compressor runs.

Other Thoughts: I was very excited to try this out since it said it was a quiet fan and at a good price. I should have known better than to try an off brand.

5 out of 5 eggswonderful fans

Pros: the pros is these fans are fairly quiet, move a good amount of air, and are cheap but quality led fans, unlike some other people I had no problem whatsoever mounting 3 of these fans inside my case.

Cons: I haven't found anything bad about these fans.

Other Thoughts: if you're looking for blue led case fans that won't break the bank I highly recommend these

1 out of 5 eggsTrash

Pros: Who knows, couldn't install it

Cons: The screws that came with the fan were thicker than the screw holes inside of the fan. It was impossible to install correctly.
Don't believe any of the positive reviews, they have to be the company themselves posting them because there's nothing good about these fans.

It's a trash product from trash engineers.

It's embarrassing to screw up something as simple as screw size.

Other Thoughts: Don't waste your money. They're loud anyway.

5 out of 5 eggsFantastic

Pros: I have purchased these fans in the past for another computer build i did for a friend and upon buying them for his PC installing and seeing just how impressive they were i decided to buy 2 for my upcoming build which i have just completed, my full tower pc case came with two terrific fans as well one front 240mm intake and one back 140mm outtake but my graphics card was sitting in a pool of hot air between the two with nothing pumping in cold air onto of it so hence the fan buy, anyways these fans were cheap, quiet, and do a excellent job moving air through my system, playing sniper elite 3 on ultra before the fans i typically would see my graphics card run an average of 70-80 degrees Celsius now i was seeing as a high 65 which is a insane difference for only installing two more top intake fans. I also like a touch of flash in my build and the blue l.e.d.s in the fans were nice but not overbearingly bright. Definitely worth the buy 10/10.

Cons: Took longer to ship than expected

Other Thoughts: Blown away by the price for performance of these fans love them would buy more if i had the room in my case.

5 out of 5 eggsGreat fans

Pros: Good air flow. Nice and quiet. Just the right amount of light from the LEDs.

Cons: None.

Other Thoughts: They need self-tapping screws. Many times these case fan screws are almost impossible to get all the way in.

5 out of 5 eggsNeeded some extra cooling

Pros: The pros for me were, it's big, it's bright, it's cool and it's quiet. The fan does what it's supposed to do. I already own 2 for the top of my case that pull air out, I'm purchasing one more for the side of my case to pull air in to replace a stock NZXT fan that the bearings have gone out of.

Cons: There are no cons other than i wish they cost less, but you are getting a superior product here. And I had never even heard of these guys before i bought this fan.

Other Thoughts: Obviously if you purchase electronics there is always the chance that something will of course arrive DOA. Do not read reviews where that's what people choose to complain about. A product arriving DOA does not always mean it is cheap or poor quality,

2 out of 5 eggsAnnoying buzz

Pros: Blue LED

Cons: Annoying buzz. Added a fan controller to reduce the speed and still hear the buzz, albeit not as noticeable, at lowest speed. Just gets worse at higher fan controller settings.

Other Thoughts: Using a pair of these as the top exhaust fans on a Corsair Air540 case.
