COUGAR CF-V12HB Vortex Hydro-Dynamic-Bearing (Fluid) 300,000 Hours 12CM Silent Cooling Fan (Black)

Pros: Quiet, plenty of airflow, what more could you ask?

Cons: N/A

Other Thoughts: I will be ordering several more of these thats how good these fans are.

Pros: Bought these to push-pull my Corsair H100i and no problems. They are very quiet and the long cable length was a plus in my Blackhawk-Ultra case.

Cons: A little pricey but worth it

Pros: They cool my Corsair iH100 Radiator in my HAF X case with 4 of them working together in push pull config.

Cons: You need to go to a big box store and buy a set of number 6 machine screws that are about one inch and 1/16 long if you wish to "Bolt" the fans to your radiator well enough.

Other Thoughts: Keeps my computer's MPower Motherboard reporting 35C while sitting on the net, so they are good fans. I like them.

Pros: Great quality
long cables
heavy duty cables
silent

Cons: none

Pros: The cfm to noise ratio is fantastic.
Replaced one intake, and one exhaust with these fans.
CPU, and system temperatures (ambient/load) dropped very significantly, all the while bringing my system to a whisper.

Cons: I would say the price...But you get what you pay for 100%

Other Thoughts: Only time will tell how they hold up, but judging by the build quality of these fans, I don't expect to be disappointed.

Included molex-3pin adapter is of good quality.

Pros: +Great Airflow
+High Quality Build
+Silent
+Includes 4pin Fan Adapter

Cons: -Color Scheme
-Price

Other Thoughts: These are very great fans and I would recommend these for everyone who want maximum airflow in their rigs.

Pros: Very quiet, no humming or whining, vibrations well controlled.

Cons: I would've enjoyed packaging that was less flashy for a better price. I'd love an OEM version.

Pros: extremely quiet, push lots of air, very good construction (this applies to the cord design as well)

Cons: little pricey

Other Thoughts: i bought these because i was looking for the quietest fans that could move enough air to cool my corsair H80i in push/pull for my audio/video workstation. these are comparable to Corsair's quiet 120mm fans (perhaps even a tad quieter) but these Cougars push MUCH more air through per dB, which gives credit to their blade and bearing design.
Keeps my Intel 3930K running at the same temps as other "loud/generic" fans (32C idle) as well as using them for case fans.
Four of these and two 80mm Vantec Stealth are the only fans in my rig and I'm VERY happy.

Pros: So far these fans are awesome. They push a tone of air and at full speed they are really quite but with a controller you don't even notice they're on.

Cons: None

Other Thoughts: I wish the ones with the blue leds weren't $20 each or I would order too of those to go in the front of my case.

Pros: Quiet operation, high airflow, solid construction and engineering.

Cons: Expensive but worth it.

Other Thoughts: This is the 3rd fan I've used with my 120mm Corsair CPU cooler and the one I'm going to keep. The Corsair fan was too noisy so I bought an Arctic Cooling F12 which was quiet but poorly constructed with thin wires and solder points. Even though this fan is much quieter my CPU temps are the same.
