The Good:
Light, almost entirely made of super light plastic.
Lots of blades for air movement
In my opinion, no LEDs which attracts bugs at night. Nothing more fun then finding spiders and insect bodies on the bottom of your case! (Sarcasm if you missed it)
Potential 90 CFM. For a 120 mm fan, that's awesome.
Comes with 3 pin converter to Molex (4 pin)

The Bad:
Somewhat loud, but hardly as bad as some other fans. 19 Decibels isn't bad.
Not free?

Conclusion:

Excellent buy for the price. Hard to find another 120 mm case fan that moves that much air for the same price.

I love the fan works great!!!! The only thing is on Amazon it say its a 90CFM but it's a really 69CFM Fan !!!!!!

Fan works just as advertised. Very quiet and very easy to install. Shipping was prompt and well packaged..NIB.

Just got two of these today and installed them. They are a little noiser than the masscool 120mm fans that were inside previously. I will say due to the higher air flow rate they cooled my cpu and MB temps by about 3 maybe 4 degrees. So for the money I paid they are a decent deal, it would be nicer if they came with a fan control to lower their r.p.m. to reduce some noise.

I goofed and bought this fan to mount as the second fan on my Hyper 212+ cpu cooler. Amazon lists this as a fan for that purpose but in reality this is a simple case fan. You need a PWM fan for the Hyper 212+. The fan itself is fine and works with the cooler but will not adjust speed when connected to the mobo. I have CM's PWM fan on the way now and will use this fan as an extra case fan which is what its really designed for.

Yes very cool on every level. The fans are great and have decreased my system temp by about 10 degrees C. System runs consistent at 30C now. They move a lot of air for sure, but they do make noise so if you're looking for a quiet system not the way to go. Since I am only concerned with performance it is perfect. When playing MP3s at normal levels the noise is not noticeable to me.

I'm very happy with the purchase.

Bought 3 of these for my antec 300 case, 2000rpm 24/7 and quiet
easy to mount comes with adapter for regular 4pin connector.

Fit perfectly into my MasterCooler NV690. Snapped right into place with no wiring issues. This fan moves a decent amount of air. I added it as an intake fan for my case since it lacked one and needed. Great price!!!!!

Nice, solid, well-constructed PC fan. About the same noise level as the other two 120mm fans that came in my case. I leave this thing on max rpm all the time, and its not really that loud. My only complaint about this fan: the case it came in said nothing about 90CFM. Still, this thing moves far more air than my 100mm fans.

Don't know why the previous guy was complaining. Love the fan moves enough air and is silent enough for my liking
