COUGAR 12CM Green LED Hydraulic (Liquid) Bearing Ultra Silent Fan 1200RPM, 64.4CFM, 16.6dBA

Pros: These fans are QUIET!!! I can't stress that enough. I had been obsessed (not sure why) with the Cooler Master Sickle Flow 120mm fans for awhile and was set on buying them for my new build. I got them and I was so disappointed. They were GREAT for airflow but they were way too loud and 3 out of the 8 I got were making rattling or buzzing noises for no obvious reasons and they didn't play nice with my fan controller either. But this isn't a review for those fans. The cougars are obviously well made and look and feel sturdy. They operate, even at high speeds, near silently. The airflow and pressure, I will admit, is not quite as good as the CMSF fans but the fact that they are quality and silent easily makes up for that. The thought put into the design is easily visible. Rubber pads for cushion when mounted against the case is a nice touch. Plus the color of the led and everything is really cool and not too over the top.

Cons: The only small thing is that these fans still produce a mild buzzing sound when throttled by my fan controller. The noise is ONLY present at setting in between max an min. I am also wondering if this is due to the fact that I have so many fans I needed to put two fans to one adjustable knob. Since I am not sure the fans are the cause of the noise, I didn't seem a reason to remove an egg. especially since many people will never use a fan controller anyways.

Other Thoughts: also, the fans are noticeably quieter than the CMSF fans even with the CMSF fans at min. and cougar at max. ....thats impressive in my book and embodies the meaning of "silent" fans.

Pros: I have bought 26 of these to use in a caselabs th10. They move a ton of air and are very quiet, even at full speed the only noise you hear is air being pushed through the grates. The color is a nice rich dark green compared to others that are more yellowish green. I will definitely be buying more as I add radiators to my build.

Cons: In a perfect world, cables could have been sleeved white to match my case.

Pros: Great quiet fan & it's green. Another win for Cougar! I own 16 Cougar fans!

Cons: None

Other Thoughts: Don't purchase the Blue 140mm there is something wrong with those!

Pros: - Quiet
- Blows real nice ;)
- Super Green
- Molex Adapter included

Cons: - Doesn't come with the Rubber pins like the Vortex series fans

Other Thoughts: I got this mounted to a Xigmatek HDD rack for my 650D case, and it works wonderfully. Glows a real nice green, keeps my drives very cool, and pushes air into the computer for extra cooling. Now I'm thinking about replacing my Vortex fans with these, make everything Green!
